Build The Right Film Recycling Route

Typical projects include LDPE/LLDPE film, flexible and printed packaging, stretch film, PP raffia and woven bags, fibres, nonwovens and selected lightweight fractions. Suitability depends on polymer compatibility, multilayer structure, printing/coatings, contamination, moisture, odour, bulk density, feeding behaviour and target output.

No. Compatible blends may be processable, while incompatible polymers, PVC, aluminium layers, heavy coatings, adhesives or barrier structures can limit quality or require sorting, compatibilisation, downcycling or rejection. Test the actual structure and define a realistic product target.

DRD can be evaluated for suitable pre-shredded film containing loose moisture, dust, sand, soil, fines or heavy particles. It may reduce water demand, but it does not remove every adhered, oily, organic or embedded contaminant and cannot replace every wet-washing duty.

Wet cleaning may be required when contamination is adhered, oily, organic, soluble or otherwise unsuitable for dry removal, or when the output specification requires a lower residual load. Compare cleaning performance, water treatment, drying, yield and cost.

Low-bulk-density film can bridge, fluctuate or feed inconsistently. Predensification may increase bulk density and support stable extrusion feeding. It should be compared with cutter-compactor, controlled/direct feeding and other preparation routes using representative film.

Another route may fit when film form, moisture, heat sensitivity, contamination, desired residence time, existing equipment or production objective differs from the PreDensifier design case. The choice should follow a feeding/preparation trial, not the material name.

Yes. MAS can define trials for cleaning, densification/feeding, extrusion, degassing, filtration and output evaluation. Agree the representative sample, trial conditions, measurements and acceptance criteria before sending material.

Quantity depends on film form, bulk density, preparation steps, equipment, trial duration and measurements. MAS should confirm the required quantity, packaging and preparation instructions after reviewing the project scope.

Output may include regranulate, pellets, re-compounds or application-specific PCR, but quality depends on input composition, contamination, moisture, preparation, extrusion, filtration and operating conditions. Define measurable colour, odour, contamination, rheology, pellet and application-property criteria.

Throughput depends on bulk density, feeding stability, moisture, contamination, polymer behaviour, filtration load, line sequence and output target. Use representative trials and a stated operating window—not a theoretical machine maximum alone.

Such applications require project-specific material control, process validation, documentation and the applicable regulatory approvals. The responsible parties, jurisdiction, intended use and approval scope must be defined; a machine alone is not a universal approval.

Compare preparation and cleaning scope, yield, throughput, water and drying, energy, consumables, labour, maintenance, downtime, rejects, material value and product acceptance. Use the same input and output assumptions for every route, and add stages only when they deliver measurable value.
