CPET stands for polyethylene film exposure. It is similar to aluminum tray but it is better than aluminum. CPET, also known as polyethylene plastic insert, is a plastic substitute for aluminum tray. CPET trays are now the preferred choice of the ready-to-eat concept. CPET is mainly used for ready-to-eat foods.
CPET technology is the fusion of plastic sheets with foam to form a durable, reusable food packaging material with a tamper-proof, reusable lid. The technology basically uses two plastic sheets fused together by thermoforming, which makes the plastic sheets rigid and durable. The outer surface of the tray is made from polyethylene film that is coated on both sides with plasticizer, and then it is laminated. This lamination protects the laminated surface from damage and moisture penetration.
The outer surface of CPET trays is usually coated with a UV resistant material to ensure that your tray does not retain heat from the oven or moisture from packaging materials. The polyethylene film also acts as a barrier between the product and any particles that may be harmful to the health of the consumers. In addition, the UV coating will help your packaging material to last longer. Thus, you are provided a long term warranty along with the long term benefits of protecting your products.
The lids of CPET trays can have two kinds of features. The first type of lids allows users to remove the food from the tray easily using a screwdriver or other suitable utensil, whereas the second kind of lid has a built in sensor that prevents the food from being removed from the tray until it reaches low temperatures. CPET lids can withstand very low temperatures and high temperatures as well. Thus they allow you to prepare different kinds of meals without having to worry about damaging the fragile outer surface of your product.
Another benefit of using CPET lids is that they allow you to use your standard oven to prepare food items such as biscuits and cake when they are placed on the lid of the tray instead of having to cook them inside the oven. This ensures that you save energy and cooking time, which can help you save money. Additionally, they are recyclable, which helps to make your household greener.
Using CPET trays in your packaging needs to comply with local and federal regulations. These trays have been certified by the Food and Drug Administration (FDA) to be low-fat and low-heat in nature, ensuring that they are safe for packaging with your standard ovens and for use with your standard ovens and stovetops. Furthermore, because they are non-stick, they are safe to use for any type of food that will not burn easily in a normal oven or on a stovetop. Lastly, they are grease resistant, making it easier to clean out of any spill, grease or dirt that might happen over time.
