13. The film has an odor

Reason 1: the smell of the resin raw material itself;

Reason 2: The extrusion temperature of the molten resin is too high, resulting in the decomposition of the resin, resulting in odor;

Cause 3: The membrane bubble is not cooled enough, and the hot air in the membrane bubble is not cleared.

solution
① Replace resin raw materials;

② Adjust the extrusion temperature;

③ Improve the cooling efficiency of the cooling wind ring, so that the membrane bubble is fully cooled.
