What are the factors affecting the biaxial tensile strength of the stretched film?

September 24, 2019

The good packaging properties of stretched film Pallet Wrapping Ldpe Film Plastic Prices are inseparable from its excellent tensile strength, especially in the two-way tensile strength, and what are the factors affecting the tensile strength of the stretched film? Stretch film manufacturers and everyone to do a detailed analysis:

1. When the stretching temperature and the stretching speed of the stretched film are constant, the lower the glass transition temperature of the material, the greater the orientation effect.
2. When the temperature and the stretching speed are constant,Clear Pallet Stretch Wrap Cling Film the larger the stretching ratio, the larger the orientation effect.
3. When the temperature and the stretching ratio are constant, the faster the stretching speed, the greater the orientation effect.
4. Under stretching conditions, the faster the cooling rate, the larger the orientation.
