![]() ![]() Some common products made from PEEK resin include blenders, kneaders, mixing paddles and scrapers, and valves and nozzles on coffee machines. For this reason, PEEK food handling components are used in both food packaging and food production processes. PEEK is safe for direct contact with delicate foods like raw lettuce or fresh dairy products even during the production process. As such, PEEK food handling products can withstand microwave use, dishwasher use, and intense temperatures when cooking directly on heat. Due to its high melting point and low coefficient of thermal expansion, PEEK has high dimensional stability. PEEK is a lightweight and strong semi-crystalline thermoplastic. Some food-grade plastics are better for packaging - they are strong, chemically resistant, and tough against stress. ![]() Since HDPE is resistant to most chemical solvents, it can prevent harsh chemicals from interacting with food and beverages. ![]() Also, HDPE is non-leaching, meaning a disinfectant cleans it quickly but dissolves in time for safe human interaction. For instance, HDPE’s high heat resistance makes it dishwasher safe - an excellent feature for food packaging. These limitations notwithstanding, HDPE is an excellent choice for creating FDA-approved plastic food containers. Further, it’s difficult to bond HDPE with other food-grade plastics, which can limit design and engineering capabilities. HDPE is also highly flammable, prone to stress cracking, and non-biodegradable. Also, HDPE is a nonporous polymer, which allows product teams to make long-lasting and easy-to-clean parts that don’t require additional maintenance.Īlthough HDPE does offer resistance to mildew, mold, and insects, it has poor weathering resistance compared to other materials on this list and it isn’t resistant to oxidizing acids. HDPE’s tensile strength, high impact resistance and melting points, and large strength-to-density ratio make it ideal for food and beverage packaging. HDPE is a thermoplastic often used in milk jugs, plastic water bottles, cutting boards, cereal box liners, grocery bags, and other plastic food packaging. However, ABS components are also prone to stress cracking due to ABS’s poor weathering and solvent resistance. Parts built with ABS are aesthetically pleasing and stand up well to applications that aren’t in extreme temperatures. This food-safe plastic is very flexible and can easily be welded to complex shapes, adding to its manufacturing diversity. Excellent resistance to strain and abrasion, maintained impact resistance at low temperatures, and insulating properties make ABS great for food transportation applications as well. ![]() ABS is a food-grade plastic safe for use in food processing tools like food processors and refrigerator linings. Acrylonitrile Butadiene Styrene (ABS)ĪBS is an amorphous plastic created by combining acrylonitrile, butadiene, and styrene polymers. Here’s everything you need to know about the top five FDA-approved plastics for food contact. Design teams working in the food and beverage industries should know what the best food-safe plastic materials are to ensure products remain safe for consumers. When it comes to food safety, it’s best to play it safe. This helps ensure consumer safety and protect your business from inadvertently breaking food safety laws. Plastics that come into contact with consumable products must adhere to FDA regulations and use materials guaranteed safe for use in plastic food packaging. Plastic food packaging is essential for maintaining product freshness and quality in transport, prolonging shelf life, and meeting Food and Drug Administration (FDA) regulations.
