Film Washing Lines

On FILM WASHING LINES the matter can be different.

For film scraps coming from collection we do not suggest a pre-washing treatment of any kind because amount of dirt is generally little and granulator should handle this pretty easily.

If contamination is not this "little" but still scraps are coming from scraps collection, we do suggest a single-shaft shredder that will last very many days without problems.

If film scrap is agro-film, silage film or stuff like that, the pre-washing step should be seriously taken into consideration.

The film we just mentioned is clearly contaminated by sand, hearth, stones, you name it and any blade of any cutting machine wears out in no time therefore a pre-washing of some sort is kind of compulsory.

 Specially for film, there are many ways to carry out this depending by which material you're feeding in and what you need at the end. (pellets to blow film, pellets for pipes or profiles extrusion, blow molding, injection molding, etc.)

For agro-film, for example, a low energy consumption wet trammel will do the job and removes 95% of dirt just spraying some water in a tumbling, perforated screen; with a washer/dryer just after it, dirt will be almost completely gone and for the rest of the washing line it will be like eating a piece of cake.

In case of silage film, where contamination is not only sand but also grass, hay, leaves and other floating contamination, it will be better to use a pre-washing machine that makes friction as well to release most of this dirt.

This machine will consume more energy but it is the only way to get rid of floating contamination.
