When recycling post-consumer films, one of the biggest challenges lies in washing and drying. Labels and glue need to be removed completely, and since the LLDPE-share is relatively high, the drying process requires additional attention and know-how. Only when all of these are addressed the right way films can be given a second life.

LLDPE & LDPE FILM | POST-COMMERCIAL

In contrast to post-consumer film, post-commercial film has a relatively low contamination level. Instead of strong odours and grease, the challenge here is to remove labels and glue. In addition, Post-consumer films contain a relatively high proportion of stretch (LLDPE), are relatively thin and have a low bulk density.

THE RECYCLING SOLUTION

As a rule, the aim of reprocessing post-consumer films is to produce new film packaging from the recyclate. Labels and adhesives must therefore be thoroughly removed, especially for the downstream extrusion process - this usually requires a high friction and, optionally, a hot wash. When planning the drying processes, the high proportion of stretch film in particular must be taken into consideration.
