CPET trays are generally resistant to a wide range of chemicals, which makes them suitable for various food packaging applications. Here's an overview of CPET's chemical resistance:
Food Contact: CPET is approved for food contact by regulatory agencies such as the FDA (U.S. Food and Drug Administration) and the EFSA (European Food Safety Authority). It is designed to safely store and package a variety of food items, including both acidic and non-acidic foods, without reacting with or leaching harmful substances into the food.
Acids and Bases: CPET is resistant to a broad spectrum of acids and bases, both weak and strong. This chemical resistance makes it suitable for packaging foods with a wide pH range, such as tomato-based sauces or citrus fruits.
Oils and Fats: CPET is also resistant to oils and fats, including vegetable oils, cooking oils, and fatty food items. It does not absorb or react with these substances, ensuring the integrity of the packaging and the quality of the food.
Alcohols: CPET typically has good resistance to various alcohols, including ethanol and methanol. This makes it suitable for packaging alcoholic beverages and products that may contain alcohol-based ingredients.
Aromas and Flavors: CPET's non-porous nature prevents the absorption of aromas and flavors from the packaged food. This ensures that the food's taste and aroma are not altered by the packaging material.
Cleaning Agents: CPET trays are often used in foodservice and can be cleaned with commercial dishwashing detergents and sanitizers without degrading or losing their integrity.
Dishwasher Safe: Some CPET trays are labeled as dishwasher-safe, indicating their resistance to dishwasher detergents and high-temperature water during cleaning cycles.
CPET's chemical resistance is a key factor in its suitability for food packaging applications, as it helps ensure the safety and quality of the packaged food products.
