PE stretch film is the most commonly used in the industry, a protective film material, which can be single or tray packaging and other bundles, PE stretch film the use of needs to have good transparency, so when we are in the test, You can take transparent plastic transmittance and haze test methods.
There are several ways to identify the PE stretch film
First Measurement
- The stretchable range of PE stretch film
The stretchable range is the stretch that can be applied while various properties in the case of certain use.
the larger the stretchable range the lower the amount of film used and thus the lower the film cost.
Second Measurement
- Stretching of PE stretch film
Stretching of PE stretch film is the ability of a film to produce elastic elongation after being subjected to tension. Stretching will thin the film and shorter the width.
Third Measurement
- The toughness of PE stretch film
The ability of the film to stretch around corners of products, boxes, and pallets allows increase puncture and tear resistance. This increased puncture resistance ensures loads will remain stabilized and secure during transportation.
The tear resistance means the ability of tear resistance of the film after being subjected to tension and being punctured.
Thus the better the toughness of PE stretch film the better the quality.
fourth Measurement
- The self adhesiveness of PE stretch film
It means the adhesion between the film layers after contact, during, and after stretching and wrapping.
for a better quality of self, adhesion film is that it should be glossy film, and to use fillers that increase adhesion to make the surface of the film moist thereby improving adhesion.
