Common features of stretch film and PE stretch film

Guangdong Huaping Hygiene Material Industrial Co.,Ltd. main products include stretch film,PE stretch film,PE perforated film,Multicolor printed film,Nonwoven Laminated film,Anti-counterfeiting Holographic film etc .Although there are many types of stretch films and their uses are different, they also have their common characteristics. After all, their basic raw materials are the same, so there is no difference in use, that is, there are some other differences in performance. Then we will briefly describe what they have in common.

1.Its own adhesion: PE stretch film itself is viscous. By adding viscous additives to the surface of the stretch film, it can moisturize the surface and improve its adhesion. The adhesive thickness of the film surface is related to the dust, humidity and other conditions on the surface of the stretched film. Its viscosity is firstly related to the type and density of the material, thickness, temperature and the use of additives.

2.Elasticity of PE stretch film: Under the action of stretching force, by increasing the strength in the direction of mechanical drafting, the length of the stretched film can be extended and the thickness of the stretched film can be reduced. Some stretch winding devices are individually stretched and wrapped around the package’s own load, which allows more stretches and prevents the load from being squeezed and necked.

3.Paving: related to pinhole resistance and also related to secondary tear resistance.

4.Useful stretch (yield) is the stretch of PE stretch film: the stretch film used in useful stretch can maintain other necessary characteristics: toughness, load integrity, etc. Its effective stretch varies by application. Of course, higher effective stretch and less stretch film can reduce total packaging costs.

In the use of PE stretch film, the purpose is the same and the effect is the same, but in use, the material may be different, so when choosing a product, we can choose the appropriate use according to different situations.
