The STRETCH FILM plays a very important role in the packaging process, and the control of the viscosity is very important for the manufacturers of STRETCH FILM during production.

There are two main methods to obtain the viscosity of STRETCH FILM. One is to add PIB or its parent material in the polymer. The other is to mix LDPE. Among them, PIB is translucent viscous liquid, which needs a process to move out, will be affected by the temperature, the viscosity is strong when the temperature is high; Not too sticky when the temperature is low, after stretching viscosity greatly reduced. If it is mixed with LDPE, the viscosity will be slightly worse, no special requirements for the equipment, relatively stable viscosity, not subject to time control.

The viscosity control of the STRETCH FILM is crucial, as good viscosity will make the outer packaging FILM of the goods stick to each other to make the goods firm

The tensile winding film is characterized by good cushioning strength, puncture resistance and tear resistance, thin thickness, good performance and price. With high tensile strength, tear strength, transparency and good retraction force, the pretensile ratio of 500%, can be assembled, waterproof, dustproof, anti-scattering and anti-theft.

Of course, due to the different types of STRETCH films, the raw materials for production are different. Some are PR as the substrate, DOA as the plasticizer and self-adhesive to produce PVCSTRETCH FILM. PESTRETCH FILM USES EVA as self-adhesive material
