How to control the stickiness of the stretch film?

Qingdao Yuanjian Packaging Technology Co., Ltd. is a very large stretch film and stretch film production and manufacturing enterprise in Qingdao, Shandong. How to control the viscosity of stretch film, let me introduce to you. The better the viscosity, the better the adhesion, and the stronger the package with the goods. There are two ways to obtain viscosity: one is to add pib or its masterbatch, and the other is to mix vldpe.

There is a process of moving out of the stretch film, which usually takes three days. In addition, it is also affected by temperature. The viscosity is high when the temperature is high, and the viscosity is not too high when the temperature is low, and the viscosity decreases after stretching. Therefore, store it within a certain temperature range. The above is about the introduction of the wound film and mixed with vldpe, the viscosity is slightly worse, but there is no special requirement for the equipment, the viscosity is relatively stable, not controlled by time, but also affected by temperature. When the temperature is higher than 30 °c, the viscosity is better, and when the temperature is lower than 15 °c, the viscosity is worse. Viscosity can be achieved by adjusting the amount of lldpe in the adhesive layer。
