 High viscosity and high tensile film
 
What is the difference between a stretched film and a protective film:
 
1. The same material, the process is not the same:
 
Stretch film is the use of PE polyethylene, is a very good toughness of the material, not easy to use ordinary plastic crusher crushing, and the protective film is the main ingredient of ethylene as masterbatch by polymerization reaction, according to the materials used and add Different plasticizers, plastic wrap is divided into a variety of types, can be applied to different occasions.
 
2. use is not the same:

3. Environmental starting point is not the same:
 
Stretch film material pe can reduce the atmospheric environmental pollution, reduce the amount of waste disposal, recycling, reduce the overall cost of packaging and other advantages, while the protective film is some manufacturers use PVC materials, this plasticizer at room temperature from the plastic film Infiltration into the packaging of high-fat content of food, the human endocrine system caused great harm.
