1. Introduction of CPET:

CPET is a polyethylene terephthalate material, which is odorless, tasteless, colorless and non-toxic. It is recognized as the best food packaging material in the world today. 

Products made of CPET material can be processed directly in the oven for various foods. It will not release any harmful substances and gases during the heating process, which is called green packaging by countries such as Europe and the United States. 

The CPET material itself has good barrier properties, the oxygen permeability is only 0.03%, and the barrier property becomes stronger the more it is heated, and the function of food preservation and quality preservation is unmatched by any material. Widely used in airline meals, it is the best choice for oven lunch boxes.

2. What are CPET materials used for?

CPET is a crystalline PET made of pure PET resin and polymerized crystalline masterbatch. It can maintain its shape at high temperature, so it is suitable for applications where temperature resistance is required. And can be used in tableware, ovens and microwave ovens, products to be heated.

CPET injection molding products can be used for electronic parts, with high heat resistance, temperature resistance of 200 degrees, high gloss and insulation.

CPET is mainly used in ready-to-eat tableware. CPET retains its shape at high temperatures and is therefore suitable for use in ovens and microwaves and products to be heated. CPE has particularly good sealing performance, blocking air and helping to improve the shelf life of food. The raw material can be used in the range of -40°C and 220°C.

3. Processing conditions of CPET materials:

a.Baking temperature 100 degrees requires 6 hours

b.Injection temperature is 270-290 degrees

c.The mold requires 110 degrees (the mold temperature must be opened), and it is difficult to succeed if the mold temperature is not opened.
