When purchasing, you need to judge whether the adhesion is good or not, you can use the stretch film to paste the item and pull it apart quickly to see the holding power, paste it several times repeatedly and then touch it with your hand until the adhesion decreases obviously, good quality stretch film adhesion will be more wear-resistant than the one with poor quality and the adhesion will be more lasting. Pay attention to judge whether the surface is self-adhesive and smooth without crystal point. Under normal circumstances, generally just produced stretch film is self-adhesive, stretch ratio can reach 5 times, on the contrary, mixed with impurities in the stretch film has a lot of irregular distribution of crystals, or the color is black. We also need to judge whether the toughness of stretch film is good or not, the better the toughness, the less possibility of brittle fracture, good quality film toughness is good, can protect the product very well.
