What kind of material is pe coating? What is its main ingredient? What happens when you encounter high temperature. Paper cups made of pe film are harmful to health.

Polyethylene (PE) particles are generally used as coatings in China, and the melting index is required to be around 7. Domestic PE particles are generally 1C7A of Yanshan Petrochemical Company. Divided into single plastic release paper and double plastic release paper; Adhesive-free release paper mainly includes Gerasin, CCK and other specially treated release papers. It will heat up when it meets high temperature. Paper cups made of pe film are harmless.

Coated paper is a composite material in which plastic particles are coated on the paper surface by a tape casting machine. Its main feature is that this composite material can be oil-proof, waterproof (relative) and heat-sealed. ?

Different uses take different characteristics: when used to package hamburgers, take its oil-proof characteristics. McDonald's is 80 degrees edible vegetable oil 10 minutes without oil leakage. When used for coated paper packaging, take its waterproof characteristics. When it is used in automatic packaging machine, it uses its heat sealing characteristics.

Extended data

PE film has the following characteristics:

Breathability: Excellent and uniform breathability, effectively isolating moisture and discharging hot air and moisture.

Flexibility: excellent hand feeling, making the product softer and more comfortable.

Mechanical properties: excellent tensile and elongation properties.

Chemical properties: not easy to corrode, simple to print, resistant to sunlight and high temperature.

PE coated non-woven fabric: the surface is smoother, colored, waterproof and high temperature resistant. Compared with PE nonwovens, PE coated nonwovens are more durable with one more process.
