CPET (Crystallized Polyethylene Terephthalate) plastic trays are an ideal packaging solution for food packaging due to their excellent heat resistance, rigidity, and durability. They are widely used in the food industry for packaging various products, including ready-to-eat meals, frozen food, and baked goods. In this article, we will discuss the advantages and applications of CPET plastic trays.

CPET Plastic Trays: The Ideal Solution for Food Packaging

What are CPET Plastic Trays?

CPET plastic trays are made from crystallized polyethylene terephthalate, which is a type of thermoplastic polymer. CPET is a crystallized form of PET (Polyethylene Terephthalate) which gives it additional strength and rigidity. CPET trays are formed by heating and molding CPET sheets into a variety of shapes and sizes. They offer excellent heat resistance, rigidity, and durability, making them an ideal packaging solution for food packaging.

Advantages of Using CPET Plastic Trays

Using CPET plastic trays offers various advantages, including:

Excellent heat resistance: CPET plastic trays can withstand high temperatures, making them suitable for use in microwave and oven applications.
Good mechanical properties: CPET plastic trays offer excellent rigidity and durability, making them suitable for various food packaging applications.
Resistance to chemicals: CPET plastic trays are resistant to chemicals, making them suitable for packaging various food products.
Recyclable and environmentally friendly: CPET plastic trays are recyclable and environmentally friendly, making them a sustainable option for food packaging.

Applications of CPET Plastic Trays

CPET plastic trays are used in various food packaging applications, including:

Ready-to-eat meals: CPET plastic trays are widely used for packaging ready-to-eat meals due to their excellent heat resistance and rigidity. They can be used in microwave and oven applications, making them ideal for ready-to-eat meals that require heating before consumption.
Frozen food: CPET plastic trays are used for packaging various frozen food products, including vegetables, fruits, and meat products. They offer excellent rigidity and durability, making them suitable for freezing applications.
Baked goods: CPET plastic trays are used for packaging various baked goods, including cakes, pastries, and bread. They offer excellent heat resistance and rigidity, making them suitable for baking applications.

The Manufacturing Process of CPET Plastic Trays

The manufacturing process of CPET plastic trays involves the following steps:

Raw material preparation: The raw materials used in the production of CPET plastic trays include CPET resin and various additives. The raw materials are mixed and melted in an extruder.
Sheet formation: The melted material is then extruded into a flat sheet using a sheet extruder. The sheet is then cooled and solidified.
Sheet trimming and inspection: The trimmed sheets are then inspected for quality and trimmed to the required size and shape.
Tray formation: The trimmed sheets are then molded into CPET trays using a thermoforming machine.
Packaging and delivery: The final product is then packaged and delivered to the customers.
