What is the reason for the peculiar smell of the film blown by the film blowing machine?

The film blowing machine is a machine that heats and melts the plastic particles and then blows them into a film.

The film blowing machine produces film suitable for all kinds of high-end film packaging. This kind of film can be widely used in light and heavy packaging due to its good barrier properties, freshness preservation, moisture proof, frost proof, oxygen barrier and oil resistance. Such as various fresh fruits, meat products, pickles, fresh milk, liquid beverages, medical supplies, etc.

So if the film blown by the film blowing machine has peculiar smell, what is the reason? Let me take you to check

①The resin material itself has peculiar smell;

②Extrusion temperature of molten resin is too high, causing resin to decompose, resulting in peculiar smell;

③The film bubble is insufficiently cooled, and the hot air in the film bubble is not exhausted cleanly.

Have you found the reason? Here are the solutions

Solution: ①Replace the resin material; ②Adjust the extrusion temperature; ③Improve the cooling efficiency of the cooling air ring to fully cool the film bubble.
