Tell you how to recognize the toughness of PVC heat shrink film

I believe we are all clear that the toughness of PVC heat shrink film is very important, then how to identify it? I'll teach you how to distinguish PVC heat shrink film.

Good PVC heat shrink film should have the following conditions:

1, transparent high gloss, can clearly show the appearance of the product, improve the effect of the exhibition, reflecting the higher grade of the goods

2, good barrier, moisture and dust performance is excellent

3, good flexibility and tensile, strong wrapping ability

4、High puncture strength

5、Strong shrinkage memory function, good retraction fastening performance.

6, the overall stability of the packaged objects, reducing the transportation process of breakage, collapse, scattered packages and other phenomena.

How to identify the toughness of PVC shrink film

Shrink film quality is mainly reflected in the toughness, with the eyes generally can not see how the quality of shrink film, looking at the same, either the color is not together only!

Identification methods:

Shrink film packaging, write the date, to be 3 ~ 4 days later, with a pen to poke a hole, if the place where the poke is just a hole, then the quality of this shrink film is good, toughness is very good.

Poor PVC heat shrink film poke up is going to burst open a very long crack, poor toughness, can not play a protective role.
