What factors can affect the performance of heat shrink film

1. Heating temperature: influenced by the PE material, the heating temperature will affect the strength of the heat shrinkable film, which in turn affects the quality. Generally speaking, in the actual heating process, the temperature should be controlled at about 160 degrees Celsius, and high or low will have different effects on its degree.


2. Heating time: Under the premise of ensuring temperature and pressure, the longer the time, the stronger the bond between the covers and the better the performance. However, if the time is not accurate, problems such as wrinkles and flatness differences may occur, affecting the overall beauty.


3. Pressure control: In order to ensure good strength, reasonable pressure is also needed. Generally speaking, reasonable and uniform pressure helps to reduce the generation rate of foam, improve the overall output rate and reduce the unwanted loss of the enterprise, so reasonable pressure is also an important factor affecting the strength of PE heat shrink film.
