PP, PET, and CPET are all types of plastic sheets that are used in a variety of industrial and commercial applications.
PP (polypropylene) is a thermoplastic polymer that is known for its high strength, high chemical resistance, and high temperature resistance. It is widely used in packaging, automotive parts, and other industrial applications.
PET (polyethylene terephthalate) is a thermoplastic polymer that is known for its high strength, high chemical resistance, and high temperature resistance. It is widely used in packaging, particularly for food and beverages, as well as in textiles and other industrial applications.
CPET (crystallized polyethylene terephthalate) is a type of PET that has been heat-treated to form a crystalline structure. This process improves the material's strength, durability, and temperature resistance. CPET is widely used in
food packaging, particularly for products that require microwave or oven heating. It can be used for trays, containers and lids.
All three materials have food contact approval and are considered safe for use in food packaging applications. However, they have different properties that make them more suited for certain applications. PP is a good choice for packaging that requires high strength and chemical resistance, while PET and CPET are good choices for packaging that requires high temperature resistance and clarity.
It is important to note that all three materials can be recycled, but the recycling process for PET and CPET is more difficult than for PP.
