Introduction

Product packaging represents far more than mere aesthetics or branding opportunity. Packaging functions as a critical barrier between the food product and the external environment, serving as the primary defence against physical contamination, chemical migration, microbiological hazards, and environmental deterioration. Within the context of food manufacturing, packaging encompasses the materials and systems employed to contain, protect, preserve, and present food products throughout their journey from production to consumer use.

Food packaging encompasses multiple layers of consideration. Primary packaging refers to materials in direct contact with the food product—such as liners, bags, films, containers, and closures. The selection and management of packaging materials demands careful attention to the product characteristics, processing conditions, storage requirements, and intended use by the consumer. Packaging suitability is not a one-size-fits-all proposition; different food products present distinct hazards and require tailored packaging solutions. A packaging material suitable for ambient-stored dry goods may prove entirely inadequate for chilled or frozen products, just as materials appropriate for low-acid foods may be unsuitable for high-fat or acidic products due to the increased risk of chemical migration.

Significance and Intent

The proper selection and management of product packaging holds profound significance for food safety, product quality, and legal compliance. Packaging failures represent a substantial source of risk across the food supply chain. When packaging is inappropriate for the intended use or when materials fail through damage or deterioration, the consequences can be severe: physical contamination from packaging fragmentation, chemical contamination from substrate migration, microbiological contamination from barrier failure, or quality degradation through oxidation, moisture ingress, or light exposure.

The regulatory and compliance landscape demands that food manufacturers exercise rigorous control over packaging materials. Across the European Union, the United States, and most other jurisdictions, legislation establishes strict requirements for packaging materials in direct contact with food. These regulations specify overall migration limits—typically 60 mg/kg or 10 mg/dm² for plastics—and numerous substance-specific migration limits for particularly hazardous chemicals such as bisphenol A (BPA), phthalates, and heavy metals. Non-compliance with migration limits creates direct food safety risk and exposes manufacturers to regulatory enforcement action, product recalls, and reputational damage.

Beyond chemical safety, packaging material integrity directly affects the physical safety of food products. Packaging materials prone to tearing, fragmentation, or deterioration introduce unacceptable risks of foreign body contamination. Similarly, packaging material durability affects product quality throughout the supply chain; inappropriate or degraded materials may permit oxidation, moisture loss, moisture ingress, or gas exchange, directly compromising the quality attributes—shelf life, sensory characteristics, nutritional content—that consumers expect.

The ideal outcome of effective packaging management is the consistent delivery of food products that remain safe, authentic, and of specified quality from the point of production through to consumer consumption. This requires not only judicious material selection based on comprehensive risk assessment but also rigorous control of packaging procurement, specification verification, storage conditions, and obsolete material management. Food manufacturers should implement systematic approaches ensuring that packaging materials support rather than compromise product safety and quality.

Overview of Compliance

Food manufacturers seeking to meet requirements related to product packaging should establish a structured framework comprising interconnected documented systems and operational practices. This framework should integrate packaging considerations into the broader food safety management system, with particular emphasis on supplier management, risk assessment, and quality control.

The documented systems necessary for effective packaging management include the following:

Supplier approval and performance monitoring procedures establish the foundation for packaging control by defining how packaging suppliers are selected, evaluated, and monitored. These procedures should incorporate risk-based assessment of supplier capability and verification of compliance with applicable food safety legislation.

Raw material risk assessments and specifications translate the hazards associated with packaging materials into documented control requirements. These documents should detail the characteristics required for packaging suitability, acceptance criteria, and testing regimens.

Packaging material storage and handling procedures ensure that packaging materials remain protected from contamination and deterioration between delivery and use. These procedures should address temperature, humidity, pest management, and physical segregation requirements.

Obsolete packaging management procedures establish mechanisms to prevent accidental use of outdated or unfit packaging materials and ensure their secure disposal in a manner that protects brand integrity.

Document control systems ensure that only current, approved packaging specifications and materials are in use, with clear communication of any changes to relevant personnel.

The operational alignment of these documented systems with day-to-day manufacturing practices is essential. Procurement staff should understand and implement supplier approval procedures. Production planners should confirm that available packaging meets current product specifications before release for use. Warehouse and goods receipt personnel should verify that stored packaging materials remain in acceptable condition and that storage conditions are maintained. Quality assurance teams should oversee the monitoring of packaging supplier performance and investigate any packaging-related complaints or anomalies.

Documented Systems

Supplier Approval and Performance Monitoring for Packaging Suppliers

Packaging suppliers represent a critical link in the food safety chain. The documented procedure for packaging supplier approval should be risk-based, with the scope and rigour of evaluation proportionate to the hazards presented by the packaging material.

Food manufacturers should undertake a documented risk assessment of each primary packaging material or group of materials to identify potential risks to product safety and quality. This assessment should consider the physical and chemical properties of the proposed material, the characteristics of the food product with which it will come into contact, processing conditions (such as thermal treatment, which may increase chemical migration), and storage conditions.

The risk assessment should specifically evaluate the potential for chemical migration. High-risk scenarios include packaging for high-fat foods, acidic foods, hot-filled products, or products with extended contact time. Low-risk scenarios may include packaging for ambient-stored, low-moisture products or packaging that does not directly contact the food product. The risk assessment should also consider the potential for physical contamination from packaging material fragmentation or deterioration.

Packaging suppliers should provide evidence of compliance with applicable food safety legislation. This may be demonstrated through:

• Valid certification to a recognised packaging safety standard such as the FSSC 22000 Packaging standard or the BRC Global Standard for Packaging Materials, with scope encompassing the specific packaging materials being supplied.
• Certificates of conformity or other formal declarations confirming that the packaging material complies with applicable food safety legislation, such as EU Regulation No. 10/2011 for plastic food contact materials or equivalent legislation in the country of production and use.
• Migration testing data demonstrating that the packaging material meets applicable overall migration limits and substance-specific migration limits under the intended conditions of use. Food manufacturers should request copies of migration test reports or certificates from packaging suppliers and should verify that testing has been conducted under conditions representative of the actual use scenario (such as the appropriate temperature, contact time, and food type simulant).
• Good manufacturing practice (GMP) certification or documented evidence that the packaging supplier operates under GMP principles, including clean facilities, controlled processes, documented quality control, and batch traceability.

Where packaging is supplied by agents, brokers, or other intermediaries rather than the direct manufacturer, food manufacturers should identify the manufacturer or packer of the packaging material and obtain approval evidence from the original source.

Ongoing performance monitoring of packaging suppliers should be documented and implemented systematically. This may include monitoring of delivery schedules, specification compliance, the nature and frequency of any quality issues, and periodic verification of certification status. Where packaging suppliers are approved based on certification, this certification should be monitored for continued validity; where certification lapses, supply should not continue until current certification is re-established.

Product Packaging Specifications

Documented specifications for primary packaging materials should define the characteristics necessary for the packaging material to be suitable for the intended use. These specifications should be sufficiently detailed to enable goods receipt personnel to make objective acceptance decisions.

Packaging specifications should address:

• Material composition and type: The specific material, resin type, grade, or composition (for example, “polyethylene terephthalate [PET], food-grade, clear, with an oxygen barrier layer”).
• Physical properties: Thickness, tensile strength, tear resistance, puncture resistance, seal strength, barrier properties (such as oxygen transmission rate or water vapour transmission rate for materials where these properties are critical to product shelf-life).
• Chemical suitability: Overall migration limit and applicable substance-specific migration limits; absence of banned or restricted substances; confirmation of compliance with applicable migration legislation for the country of sale.
• Dimensional tolerances: Width, length, diameter, volume, or other dimensional specifications, with defined acceptable tolerances.
• Print quality and accuracy (for printed packaging): Colour accuracy, print density, registration, clarity of required information.
• Contamination and defect limits: Acceptable limits for physical defects such as holes, tears, contamination, discolouration, or delamination.
• Certification and approval status: Reference to relevant certificates (such as food contact certificates or certification numbers from approved standards).

Packaging specifications should be reviewed and updated periodically, at a minimum every three years, with additional reviews triggered by changes in product formulation, processing conditions, storage conditions, legislation, or supplier capability.

Packaging Material Storage and Handling Procedures

Documentation should define how packaging materials are stored between delivery and use, with the objective of preventing contamination and deterioration.

Packaging material storage procedures should address:

• Storage location and conditions: Packaging materials should be stored in designated areas separate from production areas, raw materials, and finished products. Storage areas should protect packaging from contamination and deterioration caused by dust, moisture, pests, chemical exposure, or temperature extremes. For packaging materials susceptible to moisture or humidity effects, climate control may be necessary.
• Segregation and identification: Obsolete, damaged, or part-used packaging materials should be physically segregated from approved, full-quantity materials and clearly identified (such as through labelling or physical barriers) to prevent accidental use.
• Stock rotation: Older packaging stock should be used before newer stock (first-in, first-out principle). This is particularly important where packaging materials are subject to degradation over time or where product specifications or labelling requirements change.
• Pest and contamination prevention: Storage areas should be maintained free of pest activity and potential sources of contamination. Packaging materials should be stored on shelves or racks, elevated off the floor and away from walls, rather than directly on floors or against walls where pest harbourage or water damage is more likely.
• Environmental protection: Packaging should be kept clean and protected from damage. Boxes or other protective packaging should not be opened until materials are ready for use; once opened, part-used materials should be re-sealed or covered to prevent contamination or moisture ingress.

Obsolete Packaging Management

A documented procedure should address the management of packaging materials that are no longer suitable for use due to specification changes, damage, expiry, or labelling supersession.

The obsolete packaging management procedure should include:

• Identification and isolation: Obsolete packaging should be clearly identified (such as through labelling, tagging, or physical segregation) and isolated from approved packaging to prevent accidental use.
• Mechanisms to prevent accidental use: Physical barriers, separate storage areas, or administrative controls (such as system-level segregation in inventory management systems) should prevent obsolete packaging from entering production processes.
• Secure disposal: Obsolete packaging materials, particularly those bearing printed information, brand names, or logos, should be disposed of in a manner that renders them unusable. For printed materials such as labels or branded packaging, this may include shredding, incineration, or physical defacement (such as rendering printed matter illegible through permanent marking). Documentation should record the method and date of disposal.
• Appropriate procedures for disposal of printed materials: Where packaging bears trademark or brand information, these materials are particularly sensitive from a brand protection perspective. Organisations should document procedures ensuring that printed materials are rendered unusable in a way that prevents their illicit resale or misuse.

Obsolete packaging management procedures should include documentation of disposal activities, with records retained demonstrating that packaging has been appropriately managed.

Practical Application

Supplier Management and Packaging Procurement

In practical day-to-day operations, procurement and quality assurance personnel should implement supplier approval and monitoring procedures for packaging suppliers. When new packaging suppliers are being evaluated, quality assurance teams should review supplier documentation including manufacturing certifications, migration testing certificates, and compliance declarations. For high-risk materials (such as plastic packaging for fatty or acidic foods), procurement teams should request detailed migration testing data and should verify that testing has been conducted under representative use conditions.

Existing packaging suppliers should be subject to periodic performance review. This may occur through scheduled supplier business review meetings, analysis of packaging quality data from goods receipt inspections, or monitoring of any complaints related to packaging. Where packaging suppliers maintain certifications, these should be verified for current validity—for instance, by checking certification dates or requesting current certificates annually.

Packaging Material Receiving and Acceptance

Personnel responsible for goods receipt should verify that incoming packaging materials conform to applicable specifications. Acceptance procedures should document the checks performed, such as verification of material type and grade, visual inspection for physical damage or defects, confirmation of quantity, and verification of batch traceability information.

Where packaging materials are supplied with migration testing certificates or compliance declarations, goods receipt personnel should verify that these documents are present and, where practical, confirm that the certificate information matches the material being received. Any packaging that does not meet specifications—such as material with tears, staining, dimensional non-conformity, or missing compliance documentation—should be rejected and returned to the supplier.

Storage and Handling

Day-to-day storage practices should reflect documented procedures. Packaging materials should be stored in clean, designated areas with appropriate environmental controls (such as temperature and humidity management where necessary). Warehouse staff should ensure that packaging materials are stored off the floor, protected from dust and contamination, and protected from pest access. Older packaging stock should be rotated into use before newer stock.

Where packaging materials are stored in opened boxes or partially used, these should be re-sealed or covered to prevent contamination or moisture absorption. Staff should be trained to recognise signs of packaging deterioration—such as discolouration, brittleness, or mould growth—and to report such materials for investigation and removal from service.

Communication of Packaging Specifications

Where packaging is subject to change—such as when product specifications are updated, labels are redesigned, or regulatory information changes—goods receipt and production personnel should be informed of these changes before new packaging enters use. Documentation should be updated to reflect new specifications, and procedures should ensure that only the correct version of packaging is accepted and used in production.

Particular vigilance is necessary where packaging changes are subtle or where multiple versions of the same product or packaging design exist. For example, if a product label is updated to reflect a changed ingredient or allergen statement, production teams should confirm that only the new label version is used and that older stock does not inadvertently enter production.

Recognition of Packaging Material Hazards

Factory floor personnel should understand the potential hazards associated with packaging materials and should be trained to recognise and report issues. Production line workers should know that certain packaging materials are prone to fragmentation or tearing and should understand the importance of maintaining packaging integrity to prevent contamination. Warehouse staff should understand environmental storage requirements and should report any signs of packaging degradation or contamination.

Personnel involved in product changeovers should be trained to confirm that the packaging material being introduced is appropriate for the product being produced and matches current specifications. Where product formulations or processing conditions change, production teams should understand the implications for packaging suitability; for instance, if products transition from ambient to chilled storage, packaging material barrier properties may require reassessment.

Documentation and Records

Documented records should capture purchasing and supplier approval decisions, goods receipt inspection results, storage and handling activities, and obsolete packaging disposal. These records provide evidence that packaging materials have been appropriately managed and support traceability investigations if packaging-related issues arise.

Pitfalls to Avoid

Inadequate Supplier Evaluation

A common shortfall experienced by food manufacturers is accepting packaging based on supplier assurances or price considerations without conducting adequate risk assessment or reviewing supporting documentation. Suppliers may provide vague assurances that materials are “food-safe” without substantiating this claim through appropriate testing data or certifications. Food manufacturers should resist the temptation to simplify procurement processes by accepting incomplete evidence of compliance; instead, a structured approach should require suppliers to provide relevant certificates, compliance declarations, and (where appropriate) migration testing data.

Similarly, food manufacturers sometimes fail to identify the original source of packaging materials. Where packaging is supplied through agents or brokers, manufacturers may accept the intermediary’s assurance without identifying and evaluating the actual manufacturer or packer. This creates visibility gaps and may prevent detection of changes in the original source. Best practice involves identifying the ultimate source of packaging materials and obtaining approval evidence directly from that source.

Ineffective Specification Definition

Food manufacturers sometimes define packaging specifications in vague or ambiguous terms, such as “food-grade plastic” or “suitable for the intended use,” without more precisely defining the required characteristics. This creates ambiguity during goods receipt inspection, making it difficult for receiving staff to make objective decisions about acceptance or rejection. Additionally, vague specifications may not adequately capture hazards specific to the food product or processing conditions.

Effective specifications should be precise and measurable where possible, defining required material properties, dimensions, compliance standards, and acceptance criteria. Where subjective assessment is necessary—such as assessing print quality—specifications should include reference samples or photographs providing clarity on acceptable and unacceptable conditions.

Neglect of Obsolete Packaging Management

A frequent gap in packaging control is the failure to establish effective procedures for managing obsolete packaging. Outdated labels or packaging bearing superseded product information may inadvertently enter production if not adequately segregated and controlled. In some cases, organisations have discovered that old packaging was in use months or years after product specifications or labels were updated, resulting in mislabelled products reaching consumers or creating potential food safety risks.

Effective obsolete packaging management requires both physical segregation (ensuring that old packaging is stored separately from current stock) and administrative controls (such as destruction records confirming that old packaging has been disposed of rather than remaining in inventory). Where printed packaging is concerned, particular attention should be given to rendering materials unusable in a manner preventing their misappropriation.

Inadequate Storage Conditions

Packaging materials are sometimes stored in environments that expose them to contamination or deterioration. Examples include storing packaging materials directly on production area floors, storing packaging near raw materials or production areas prone to dust generation, or storing materials in environments with high humidity or pest activity. These practices compromise the integrity of packaging materials before they are even used in production.

Best practice requires designated storage areas with appropriate environmental conditions. Packaging should be stored off the floor, protected from contamination sources, and segregated from production areas. Environmental monitoring should confirm that storage conditions remain suitable, with particular attention to temperature and humidity where packaging materials are sensitive to these factors.

Absent or Inadequate Migration Testing Data

A significant vulnerability is the absence of migration testing data for packaging materials, particularly where packaging is used for high-risk products such as fatty foods, acidic foods, or products subjected to elevated temperatures. Some food manufacturers may assume that all “food-grade” packaging automatically complies with migration limits, without verifying that appropriate testing has been conducted under representative use conditions.

In reality, the extent of chemical migration from packaging materials is highly dependent on food characteristics, temperature, contact time, and food contact surface area. A packaging material tested under one set of conditions may not be suitable for a different food product or processing scenario. Food manufacturers should ensure that migration testing has been conducted under conditions representative of actual use and should document the conditions under which suitability has been demonstrated.

Insufficient Supplier Monitoring

Food manufacturers sometimes approve packaging suppliers and subsequently fail to monitor their continued compliance with requirements. Supplier certifications may lapse, supplier manufacturing processes may change, or quality issues may emerge that go undetected. Without ongoing performance monitoring, food manufacturers may continue to accept packaging that no longer meets standards.

Effective supplier management requires periodic review of supplier performance, verification of continued certification status, and investigation of any quality issues. This monitoring may be integrated into broader supplier performance reviews or may take the form of periodic audits or certification verification.

In Summary

Product packaging represents a critical component of the food safety and quality management system, meriting systematic and rigorous control. The core elements of effective packaging management are risk assessment of packaging hazards, supplier approval based on objective evidence of compliance with applicable legislation, clear specification of required packaging characteristics, appropriate storage and handling to prevent contamination or deterioration, and secure management of obsolete materials.

Food manufacturers should treat packaging not as a peripheral concern but as an integral element of product control. The investment in comprehensive supplier approval procedures, detailed packaging specifications, and appropriate storage practices yields substantial returns in terms of reduced food safety risk, improved product quality, and simplified traceability investigations if issues arise.

The principles underlying effective packaging management are fundamentally straightforward: the packaging material must be fit for its intended use, must comply with applicable food safety legislation, must be protected from contamination and deterioration, and must be appropriately specified so that production personnel can verify conformity. By implementing these principles in structured, documented processes integrated with day-to-day operational practices, food manufacturers can be confident that their packaging systems support the consistent delivery of safe, authentic, good-quality food products to consumers.
