How To Judge The Quality Of The Stretch Winding Film Purchased?

Stretch wrap film is a comprehensive version of the wrap film, the stretch wrap film has both the viscosity of the wrap film and the tensile property of the stretch film, which also shows that the stretch wrap film is widely used. How to judge the quality of the stretch winding film purchased? The following stretch winding film Xiaobian and you tell about.
Stretch winding film manufacturer's products have the advantages of convenient use, economic benefits, and we should pay attention to identify its quality when we buy.

First, it is necessary to test its tensile property. Tensile is the ability to stretch the wound film after tensile force. If the quality is good, the length will be extended after stretching, and within a certain range, it will not break. Then we should pay attention to toughness, that is, the comprehensive performance of the film resistance to puncture and tear. The risk value of the degree of tear resistance must be transverse, that is, perpendicular to the direction of the machine operation, because tearing in this direction will make the package loose, even if the longitudinal tear, the package can remain firm, so the better the toughness of the stretched winding film is the better the quality. The third is self-adhesive, which refers to the adhesion between wound films after contact. This property can make the packaging items tight and not loose during the stretching and wrapping process and after wrapping. Among them, self-viscosity is affected by a variety of external factors, such as humidity, dust and pollutants, which is also an important indicator to test the quality of the stretched winding film.
