Want to achieve the desired tensile membrane [Import] "delivered"

Imported stretch film is at room temperature indoors, using mechanical means stretching the film tensile force generated by the deformation stress, will bind tightly to facilitate cargo transport, storage and packaging a way that is very popular internationally as a package form. Imported resin and advanced Spread film extrusion production process. Having tensile properties, tear resistance, penetration resistance, the transparency, and good self-adhesive retraction rate, packing tightly, not loose and so on.
Import stretched film should be stored at a temperature between 15 ℃ ~ 25 ℃, if less than 15 ℃ or above 30 ℃ may tack on a bit weak! To ensure stretched film effect, should choose to remain at 15 ℃ ~ 25 between ℃.
Viscosity control
Good adhesion stretched film imports of goods outside of the packaging film and layers stick together to make goods firm, sticky stretch film Being There are two main methods: one is to add PIB or parent material in the polymer; another is blended VLDPE. PIB is translucent viscous liquid, directly add the need for special equipment or modify the equipment, generally used PIB masterbatch. PIB process of moving out there, generally three days, also affected by temperature, the temperature is high adhesive strength; the temperature is low is not sticky, after stretching far less sticky. Therefore finished film is best stored in a certain temperature range (recommended storage temperature is between 15 ℃ ~ 25 ℃). Blended VLDPE, sticky bit weak, but no special requirements for equipment, viscosity is relatively stable, without time control, but also affected by temperature, the temperature is higher than 30 ℃, relatively sticky, less than 15 ℃, somewhat less viscous, can by adjusting the amount of adhesive layer of LLDPE to achieve the desired viscosity. Multi-layer co-extrusion using this method.
