Does high temperature affect the stretch film

We all know that the stretch film is sticky to a certain extent, but many people find that after a period of storage, the viscosity of the stretch film is reduced or even non-sticky. Why?
When storing stretch film, we tend to pay more attention to the factors of drying and ventilation of the surrounding environment, but we often ignore a significant factor: temperature. The influence of temperature on the wrapping film is enormous because most of the tackifiers of the wrapping film are low molecular polyisobutylene, which is what we often call PIB. When storing the stretch film, should pay attention to the tightness of the packaging. During storage, the migration speed of PIB increases, so the viscosity of the stretch film will also increase. When the temperature decreases, the migration speed of the stretch film will decrease, so its Viscosity is also reduced.
Generally speaking, we will store the stretched film in a high-temperature environment in the early stage to increase the viscosity. The purpose is to make the PIB in the stretched film sediment quickly, and the viscosity will also increase. When the viscosity increases to the extent we need, The storage temperature can lower, and the wrapping film can be stored in a temperature environment of about 20 degrees Celsius.
As a stretch film manufacturer, we even consider the importance of temperature when the stretch film is stored. Therefore, when we store the stretch film, we must pay attention to the dry and ventilated environment and pay attention to factors such as temperature conditions.
