What is the difference between stretch film and protective film

In the industry, stretched film has many advantages, and stretched film has also been widely used. Stretched film is generally made by adding viscous additives to PE film material, such as PIB masterbatch, after casting. There are many types of protective films. The most common is to coat a layer of glue on the surface of the blown PE film, which is similar to the transparent tape in daily life. It is mainly used to protect the solid surface and can be torn off when not in use. So what is the difference between stretch film and protective film?




What is the difference between stretch film and protective film:
1. The material is the same but the process is different:
The stretch film is made of PE polyethylene, which is a material with very good toughness. It is not easy to be crushed by ordinary plastic crushers. The main material of the protective film is made of ethylene as a masterbatch through polymerization. According to the materials used and additives Different plasticizers, there are many types of cling film, which can be applied to different occasions.

2. Different uses:
Stretch film has the characteristics of high flexibility, not easy to break, strong blast resistance, strong impact resistance, strong tear resistance, strong tensile force, and can replace box packaging. It is widely used in collective packaging and Packed on a pallet. The protective film is mainly used for microwave food heating, refrigerator food preservation, fresh and cooked food packaging and other occasions, in the food packaging field of family life, supermarket stores, hotels, restaurants and industrial production;

3. The starting point of environmental protection is different:
The material pe of the stretch film can reduce atmospheric pollution, reduce waste disposal, recycling, and reduce overall packaging costs, while some manufacturers use PVC materials for protective films. This plasticizer can be removed from the cling film at room temperature. Penetrating into packaged foods with high fat content will cause greater harm to the human endocrine system.

What is the difference between the above stretch film and the protective film is shared here. You can distinguish it when you buy the stretch film and the protective film. You can also choose your own stretch film or protective film according to your different needs.
