LDPE and LLDPE film comes from several distinct collection streams, each with different contamination characteristics. Post-industrial LDPE/LLDPE: trim rolls, off-specification production, stretch wrap from manufacturing facilities, and pallet wrap from logistics operations. This stream is typically clean, consistent, and can be processed with minimal washing. Post-commercial LDPE/LLDPE: collected from supermarkets, distribution centres, and retail operations — shrink film, stretch wrap, carrier bags. Contamination includes food residues, label adhesives, and some soil. Requires friction washing but typically does not need hot wash. Post-consumer LLDPE/LDPE: carrier bags, food packaging film, mixed film packaging from household collection. Highest contamination — food residues, inks, adhesives, contamination from mixed collection. Typically requires hot wash for acceptable output quality. The washing plant design must be matched to the input stream. A line designed for clean post-industrial film will be under-specified for post-consumer household film collection. Confirm the input stream specification with the machinery supplier.
