The air permeability of the stretch wrapping film is one of the important properties of the stretched film. The correct adjustment method is to adjust the amount of LLDPE to a suitable viscosity, and you can also add PIB or other master batches. It takes a period of time to move out, but it is also affected by temperature.
When the temperature is high, the viscosity is strong, when the temperature is low, the stretch and viscosity are low. The viscosity of the stretch film is greatly reduced after stretching, so a certain temperature needs to be controlled, and the air permeability of the stretch film also determines its quality Important indicators.
How to improve the breathability of stretch wrapping film?
Among them, pay attention to the pressure difference between high pressure and low pressure. The inspection process is carried out under the pressure difference condition of the low pressure chamber. To check the accuracy of the test data, how to maintain the air permeability of the stretched film must pay attention to the sealing of each system in the process instrument Sex.
