Food manufacturers must comply with strict regulations about packaging materials for every product they make. Testing food contact materials plays a significant role that ensures products meet safety standards and regulatory requirements. A food manufacturer's responsibility goes beyond ingredient quality to guarantee the safety of materials that directly touch food products.
Detailed testing protocols verify the safety of packaging materials like glass, plastic, paper, metal and other components. Migration testing and other specialised procedures help ensure food contact materials meet EU and other nations' regulations. In this blog post, I explain more about food contact material testing and help you understand the methods, challenges, and effects on your food manufacturing processes.
Food contact materials (FCMs) include all materials and articles that directly or indirectly touch your food products throughout production, processing, storage, preparation, and serving. Understanding FCMs is important because there are thousands of chemicals in FCMs that could possibly migrate into food and drink. For example, in Europe alone it’s possible to use more than 8,000 chemicals in food packaging and other FCMs. With many of these chemicals associated with negative effects on the environment and our health, you can see why food contact materials testing is so important.
FCMs that you should think about include:
You must ensure these materials meet fundamental safety principles. The regulations state that FCMs should not release harmful levels of constituents into food or alter food's composition, taste, and odour unacceptably.
Plastic FCMs require strict adherence to specific migration limits. The overall migration limit (OML) states that total migration to food cannot go beyond 60mg/kg food, or 10 mg/dm² of the contact material. Businesses supplying food contact materials need to supply written evidence of compliance with the relevant requirements. This declaration of compliance (DoC) outlines manufacturer information, material specifications, and compliance confirmations.
It's worth mentioning that plastics and ceramics have specific EU regulations with safety limits for individual chemicals. However, materials like paper, card, inks, coatings, and adhesives don't fall under specific EU regulations. This regulatory coverage variation demands extra vigilance in material selection and testing processes, especially when you have to choose and test materials.
Food contact materials need precise analytical testing methods to meet safety standards. Your testing strategy must focus on overall migration and specific migration testing.
Overall migration testing measures the total amount of non-volatile substances that can move from packaging into food. Current regulations set an Overall Migration Limit (OML) of 10 mg/dm² for general plastic FCMs. Materials meant for infants and young children face stricter limits of 60 mg/kg food.
Your testing protocol needs these key analytical methods:
Testing requires food simulants that match real-life conditions. A combination of simulants A (10% ethanol), B (3% acetic acid), and D2 (vegetable oil) works for all food types. Your test conditions should reflect the worst-case scenario based on temperature and exposure time.
Specific migration testing analyses individual substances through targeted analytical methods. This becomes crucial especially when you have substances of concern like bisphenol A, primary aromatic amines, and phthalates. Your testing lab should have method development and validation capabilities in various technologies to deliver accurate results.
The food packaging industry faces major challenges in ensuring complete food contact material safety today.
Your testing protocols must tackle several key challenges:
The complex nature of packaging materials makes this especially difficult as they can contain up to seven different layers. Various chemicals make this even more challenging. Per- and polyfluoroalkyl substances (PFAS) and toxic heavy metals have become serious concerns.
Climate change and globalisation affect food safety testing strategies. These factors can alter how contaminants occur and persist in the environment. The lack of aligned EU regulations for certain materials creates more compliance challenges and potential trade barriers.
Quality assurance demands testing protocols that cover both known and emerging risks. New agricultural practises, industrial activities, and technological advances can all affect food safety.
Your investment in detailed FCM testing affects consumer safety directly. Recent data reveals food recalls moving toward a five-year high, and packaging defects lead to major recalls. The USDA food recalls jumped 27.9% in Q3 2023 compared to Q2 according to Sedgwick, a risk and benefit assessment firm. These numbers show why detailed testing protocols matter.
FCM testing protects your brand and ensures product safety. The market's progress reflects new trends like antimicrobial coatings and smart packaging technologies. Your testing protocols need to adapt to these innovations while meeting national and international standards.
Poor testing can hit your finances hard. A recent case showed packaging defects forced a recall of 84,000 cases of processed cheese products. Reliable FCM testing procedures do more than meet regulatory requirements – they protect your business from expensive product recalls and reputational damage.
FCM testing needs advanced technical expertise and complete analytical capabilities. Modern FCM testing protocols must handle thousands of regulated substances, complex migration patterns, and emerging risks from non-intentionally added substances. The testing strategy requires precise analytical methods, such as GC-MS, LC-MS/MS, HPLC-DAD, and ICP-MS technologies with deep regulatory knowledge.

Quality FCM testing protects against recalls that can get pricey and damage reputation, especially when you have a complex food packaging industry. Recent data shows major increases in food recalls which highlights the importance of complete testing protocols and expert analysis. Your steadfast dedication to strict FCM testing shows regulatory compliance and makes your business a leader in food safety. This builds lasting consumer trust through verified quality assurance.

Food contact materials (FCMs) encompass all materials and articles designed to come into contact with food and beverages. This includes a variety of items such as containers, packaging, kitchen tools, cutlery, and dishes, made from different materials like ceramics, plastic, metal, paper, wood, rubber, glass, silicone, Teflon, or enamelware.
Testing food products is a critical step in the food manufacturing process, despite being the final stage. It is essential to ensure that food is free from physical, chemical, and biological hazards, thereby confirming its safety for consumption.
Food contact testing involves the analysis of materials used in food packaging to ensure their safety when in contact with food. This testing is crucial for protecting human health and ensuring that products can be safely introduced to the global market.
Food contact surfaces are any surfaces that may directly interact with any product of the food industry, for example, exposed meat or poultry products. In this case, examples include conveyor belts, tabletops, saw blades, augers, and stuffers, among others
