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.

LLDPE & LDPE FILMS
Post-commercial film refers in general to transparent plastic films with a high stretch content, which are recovered from supermarkets and other businesses. These soft films are often contaminated with organic matter and paper labels, which must be removed and separated in a complex procedure. Drying thin stretch wrap poses a special challenge and is handled efficiently by a centrifuge from LINDNER’s Loop Dryer series. The goal is to produce a granulate for subsequent extrusion that is as transparent as possible and free of contaminants, with the same market quality as new material.
