The Quality Of Stretch Wound Film Is Identified From Several Aspects

In recent years, stretch film is more and more widely used in product packaging, and we should pay attention to distinguish its quality when we buy products from stretch winding film manufacturers.
Tensile is the ability to stretch the winding film after tension, if good quality will be extended after stretching length, and in a certain limit, will not break, only with such tensile properties, in order to better packaging items. Toughness refers to the film's combined properties of puncture and tear resistance. The better the toughness of the stretch film, the better the quality. Self-adhesive refers to the adhesion between stretch films after contact. This property can make the package tight and not loose during the stretch winding process and after wrapping.
Among them, self-adhesive will be affected by a variety of external factors, such as humidity, stains and dust pollution, which is an important standard to test its quality.
