lldpe stretch film viscosity
stretch film viscosity:
The excellent viscosity of Stretch film makes the outer packaging of goods stick to each layer to make the goods firm. There are two main methods to obtain the viscosity: 1. Add PIB or its parent material in the polymer; 2. 2. It is mixed with VLDPE. PIB is a translucent viscous liquid, which directly needs special equipment or equipment modification. Generally, Stretch film manufacturers use PIB master material.
There is a process for stretch film PIB to move out, stretch film viscosity generally takes 4 days. Others are also affected by temperature, and the stretch film viscosity is strong when the temperature is high. Not too sticky when the temperature is low, after stretching viscosity greatly reduced. Therefore, the product membrane is stored in a certain temperature scale, the storage temperature is recommended at 20℃to30℃. Mixing LDPE, stretch film viscosity is slightly poor, but there is no special requirements for the equipment, viscosity is relatively stable, not controlled by the moment, but also affected by the temperature, temperature higher than 40℃ is relatively sticky, less than 20℃ stretch film viscosity is slightly poor, you can adjust the amount of LLDPE adhesive layer, in order to reach the required viscosity. This method is often used for co-extrusion of five floors.
