What is the difference between stretching film and protective film?

1. Same materials, different processes:

Laval film is made of P polyethylene, which is a material with good toughness. Generally, plastic crushers cannot crush it. On the other hand, the main material of protective film is made from ethylene as the base material through polymerization reaction. According to the materials used and the addition of plasticizers, the protective film can be divided into various types and can be suitable for various situations.

2. Different uses:

Stretching film is mainly used for the sales and transportation of various products such as alcohol, cans, mineral water, various beverages, fabrics, non food, pharmaceutical packaging, etc. Protective film is mainly used for microwave food heating, refrigerator food storage, fresh and home cooked food packaging, and other occasions, family life, supermarket sales, and protective film

3. The starting point for environmental protection is different:

The stretching film material PE has the advantages of reducing atmospheric environmental pollution, reducing waste treatment, recycling, and reducing packaging costs. However, PC material is widely used in the protective film part, and this plasticizer can penetrate high fat foods packaged with plastic wrap at room temperature.
