When it comes to food packaging and containers, food-grade certification is essential to ensure the safety and quality of the products we use. Two materials commonly used in food-grade products are silicone and plastic, both of which have different certifications that make them safe for contact with food. In this article, we’ll explore the different certifications for food-grade silicone and plastic, their differences and uses.
Food grade silicone certification:
- LFGB certification: This certification is required in the European Union, indicating that silicone materials meet the requirements of food, health and safety laws and standards. Silicone products certified by LFGB are safe for direct contact with food. There are various test methods for LFGB certification, including migratory substances, heavy metals, odor and flavor transmission tests.
- FDA certification: FDA (Food and Drug Administration) is a regulatory agency in the United States that ensures the safety and effectiveness of food, drugs and medical devices. FDA-approved silicone products are considered safe for use in food contact applications. The FDA certification process evaluates silicone materials for their chemical composition, physical properties, and other factors to ensure they are compatible for food use.
- Medical Grade Silicone Certification: This certification indicates that the silicone material meets USP Class VI and ISO 10993 standards for biocompatibility. Medical grade silicone is also suitable for food contact applications as it is highly biocompatible and sterile. Medical grade silicone is often used in healthcare and medical products and therefore needs to adhere to stricter safety standards.
Food Grade Plastic Certification:
- PET and HDPE Certification: Polyethylene terephthalate (PET) and high-density polyethylene (HDPE) are the two most common types of plastic used in food packaging and containers. Both materials are FDA approved for food contact and are considered safe for use in food and beverage containers.
- PP, PVC, Polystyrene, Polyethylene, Polycarbonate and Nylon Approvals: These plastics also have FDA approval for food contact. However, they have varying degrees of safety and compatibility with food use. For example, polystyrene is not recommended for hot food or liquids due to its low heat resistance, while polyethylene is suitable for both cold and hot temperatures.
- LFGB certification: Similar to silicone, food-grade plastics can also have LFGB certification to be used in the EU. LFGB certified plastics have been tested and found safe for use in food contact applications.
The main difference between these certifications is their testing standards and requirements. For example, the FDA certification process for silicone evaluates the material’s impact on food and the potential risk of chemical migration, while certification for medical-grade silicone focuses on biocompatibility and sterilization. Likewise, the certification of plastics has different requirements depending on the level of safety and compatibility with food use.
In terms of usage, these certifications can help consumers make informed choices about the products they use in food packaging and containers. For example, PET and HDPE are commonly used in water bottles, while polycarbonate is used in baby bottles and cups for its durability and strength. LFGB certified silicones and plastics are suitable for a variety of food applications including bakery molds, cookware and food storage containers.
Overall, the certification of food-grade silicones and plastics plays a vital role in ensuring the safety and quality of the products we use in food contact applications. By understanding the differences between these certifications, consumers can make informed choices about the products they use and feel confident that they and their families are safe.
