Introduction – Why This Testing Matters
Food products such as dairy, beverages, bakery items, snacks, ready-to-eat meals, oils, spices, and processed foods are composed of complex formulations packaged in various materials. When a product is stored, the interaction between the packaging and the food can lead to the transfer of chemical substances. This process, known as migration, can result in the contamination of the food with packaging components, compromising its safety, stability, and quality.
Migration testing helps ensure that food products remain safe and unaltered throughout their shelf life. For manufacturers and brand owners, this testing is essential to guarantee product integrity, meet safety requirements, avoid packaging-related contamination, and maintain consumer trust.
Regulatory authorities such as FSSAI, EFSA, FDA, and international regulators increasingly focus on packaging safety and its potential impact on food product quality.
What is Migration Testing?
Migration testing in food packaging is a laboratory analysis used to evaluate the transfer of substances from primary packaging materials (such as plastics, glass, metals, paper, or laminates) into the food product. The objective is to ensure that the packaging does not release harmful or reactive substances that could alter the food’s safety, composition, or quality.
This testing applies to:
- Primary packaging: pouches, trays, bottles, cans, wraps, and lids.
- All food categories: dairy, beverages, bakery, snacks, frozen foods, and ready-to-eat meals
- Packaging materials: plastics (PE, PP, PET, PVC), glass, metals, paper, board, and multilayer laminates.
- Finished products: to assess overall stability and safety in the final packaged state.
Why is This Testing Important?
Migration testing is strongly recommended and, in many cases, required to ensure consumer safety, product stability, and regulatory compliance.
Key reasons include:
- Consumer safety by preventing chemical contamination from packaging
- Regulatory compliance with food contact material and packaging safety standards
- Product stability assurance over shelf life
- Quality assurance and brand protection by avoiding unexpected formulation changes
Risks of non-compliance:
- Product degradation or unexpected taste/odor changes.
- Regulatory non-compliance and market rejection.
- Consumer complaints due to altered product quality.
- Damage to brand reputation and costly product recalls.
Regular migration testing helps manufacturers select appropriate packaging materials and maintain consistent product quality throughout the product’s lifecycle.
Applicable Standards, Guidelines & Regulations
Indian
- Food Safety and Standards Act, 2006
- FSSAI Food Safety and Standards (Packaging) Regulations, 2018
- BIS standards for food packaging materials
- Plastic Waste Management Rules
International
- EU Regulation (EC) No. 1935/2004 on food contact materials
- EU Plastics Regulation (EU) No. 10/2011

Key Test Parameters
Migration testing for food packaging materials typically includes analysis for:
- Overall migration – total non-volatile residues transferred from packaging to food or food simulants
- Specific migration – targeted analysis for individual substances such as:
- Plasticizers (e.g., phthalates)
- Heavy metals from packaging components
- Residual monomers (e.g., styrene, BPA, formaldehyde)
- Antioxidants and stabilizers
- Colorants and printing ink components
- Per- and polyfluoroalkyl substances (PFAS)
- Mineral oils (MOSH/MOAH)
- Volatile organic compounds (VOCs)
- Extractable studies – using food simulants (such as water, ethanol, acetic acid, and olive oil) based on food type, with compliance measured against specific migration limits (SMLs) or overall migration limits (OML) defined in regulations like the EU Plastics Regulation (EU) No. 10/2011 or FSSAI packaging requirements
Who Needs This Testing?
Migration testing is essential for:
- Food manufacturers developing new products or changing packaging.
- Brand owners and private-label companies ensuring supplier packaging quality.
- Importers and exporters meeting destination market requirements
- Startups launching new food brands
- Packaging suppliers providing primary containers for food products
Common Challenges Faced by Manufacturers
Manufacturers often face challenges such as:
- Incompatibility between food formulation and packaging material
- Unexpected migration from printed labels, inks, or adhesives
- Lack of supplier data on packaging composition
- Variability in packaging quality from different sources
- Regulatory uncertainty regarding packaging requirements across markets
Early-stage migration testing and supplier qualification help mitigate these risks.
How to Choose the Right Testing Laboratory
When selecting a laboratory for migration testing, consider:
- Accreditation under ISO/IEC 17025
- Expertise in food product and packaging interactions
- Capability to perform both overall and specific migration studies
- Knowledge of Indian and international food packaging regulations
- Ability to work with food simulants and complex food matrices
An experienced laboratory ensures reliable results and compliance assurance.

Conclusion
Migration testing is a critical requirement for ensuring food product safety, stability, and regulatory compliance. It verifies that packaging materials do not compromise the food’s integrity or introduce harmful substances over time.
By working with accredited laboratories and conducting regular migration studies, food manufacturers can reduce compliance risks, avoid packaging-related failures, and build consumer trust. Early consultation with testing experts ensures smooth product approvals and successful market entry.
Frequently Asked Questions
Q. Is migration testing mandatory for food packaging in India/FSSAI?
