Common problems and solutions for the use of PVC heat shrinkable film

1. Flatulence: The hot air is retained in the shrink film

Solution:

1. Increase the number of air vents to speed up the leakage of air from the shrink film.

2. Slow down the conveyor belt speed of the packaging machine, so that the hot air has a longer time to leak out of the shrink film.

3. Raising the temperature of the packaging machine will help air leak out of the PVC heat shrinkable film.

2. Atomization: The surface of the shrink film becomes blurry, like a mist

Solution:

1. Lower the temperature of the packaging machine, the temperature is too high is the cause of the atomization of the shrink film.

2. Increase the conveyor belt speed of the packaging machine to reduce the time for the shrink film to contact with heat.

In the process of shrink wrapping, PVC heat shrink film often encounters some problems, such as flatulence and atomization of shrink film. These problems can be corrected by adjusting the machine settings, most commonly adjusting the temperature of the packaging machine, the speed of the circulating air, the speed of the conveyor belt, the number of air vents and the size of the shrink film.
