Manufacturing operations generate plastic film waste in forms that most recycling guidance does not adequately address. Consumer plastic film guidance focuses on packaging and carrier bags; industrial manufacturing film waste is different in character, often in larger sheets or rolls, generated in high volumes at consistent polymer types, and much more suitable for high-value baling programmes than the mixed consumer film that retailers and logistics operations handle.
A packaging manufacturer, food producer, or industrial goods manufacturer generating plastic film waste as a production byproduct has a significantly better commercial recycling opportunity than most other businesses, precisely because the film is consistent in polymer type, generated at predictable volumes, and often clean enough to command premium recycling rates. This article covers the main plastic film categories generated in UK manufacturing, the equipment that makes baling viable at an industrial scale, and the market routes available for each film type.
The plastic film categories generated in manufacturing differ meaningfully from retail packaging waste. Production film trim from blown film lines and cast film operations is typically pure, single-polymer material with known grade characteristics. Reject film from quality control processes is similar in composition to production trim. Protective film used to cover the product during storage and transit is usually LDPE or LLDPE. Shrink sleeve offcuts from label application are often PVC or PETG rather than LDPE, requiring separate streams.
Why Manufacturing Film Commands Better Recycling Rates
Consumer film recycling faces an inherent contamination challenge: consumer plastic film is mixed at source, often food-contaminated, and rarely in a consistent grade. Manufacturing film waste, by contrast, is often generated at a consistent polymer grade directly from the production process. A film manufacturing operation generating LDPE trim has a known, consistent raw material that recyclers can process without costly sorting and grade analysis. This consistency commands a price premium of 20 to 50% over mixed consumer film in most UK and European film recycling markets.
Grade consistency also means that manufacturing film waste can be returned directly to film reprocessors who compound it back into film raw material. This closed-loop or near-closed-loop route produces the highest per-tonne value because it displaces the cost of virgin polymer rather than competing in the lower-value general recycling market. Manufacturers with large film waste volumes should explore direct reprocessor relationships alongside or instead of broker arrangements.
For manufacturing operations baling film waste at industrial volumes, Gradeall’s GV500 vertical baler provides the throughput capacity for continuous film baling alongside production operations. The G-Eco 500 baler handles the mid-range of manufacturing film volumes where a mill-size bale weight is appropriate for the buyer’s collection economics.
Multi-layer barrier films, used in food packaging for their oxygen and moisture barrier properties, are one of the most challenging plastic film categories for recycling. These films combine two or more incompatible polymer types in co-extruded or laminated structures: polyethene/polyamide (PE/PA), polyethene/EVOH, or polyester/PE constructions are common in food packaging manufacturing. The polymer incompatibility means these films cannot be recycled in standard mono-polymer film streams without extensive processing.
For manufacturers generating multi-layer barrier film waste, the recycling options are: specialist chemical recycling where available, energy recovery through RDF or direct fuel use, or in some cases, returning the film to the laminate manufacturer for closed-loop processing. Standard physical film recycling through a baling and film recycler route is not appropriate for multi-layer films without confirming that the specific recycler has the delamination capability for the polymer combination involved.
“Multi-layer film is the area where we most often see manufacturers invest in baling for the wrong stream,” says Conor Murphy, Director of Gradeall International. “If the film is multi-layer barrier, it needs a different route from mono-layer LDPE trim. Characterising the film waste stream before specifying equipment avoids the disappointment of a bale that no film recycler will accept.”
A manufacturing film baling programme requires a film collection system adjacent to each film generation point on the production floor, an appropriate baler sized to the daily film generation volume, and a buyer relationship established before production begins. The collection system for manufacturing film is typically a large Gaylord box or roll-off bin adjacent to each trim point, with operatives loading film directly rather than carrying it to a distant collection area.
For manufacturers also managing other recyclable streams, including cardboard from material deliveries, Gradeall’s full vertical baler range provides the flexibility to bale both film and cardboard through the same operational infrastructure, maximising the return on the equipment investment.
Some film suppliers and raw material producers operate take-back programmes for manufacturing trim and reject film generated from their polymer grades. These programmes are commercially attractive because they recover a known, clean grade of material that can be fed directly back into the supplier’s manufacturing process. Contact your primary film suppliers to ask about take-back programmes; these are not universally available but are increasingly offered as EPR obligations push producers to take responsibility for the end-of-life management of their materials.
Film granulation, passing baled film through a granulator to produce regrind pellets, produces a higher-value output than film bales because the granulated material is closer to a raw material form that compounders and film producers can use directly. However, granulation requires significant capital investment in granulation equipment, is energy-intensive, and is only economically viable at higher film volumes than baling. The typical progression is: start with baling to access the recycling market, then evaluate granulation investment when bale volumes reach the level where the premium on granulated output justifies the capital cost.
For manufacturing operations generating clean, single-polymer film, a baling programme is typically worthwhile from around 100 kg per week. At this volume, a compact vertical baler producing one to two bales per week generates meaningful bale revenue and reduces the disposal cost of film that previously went to general waste. Higher-volume operations above 500 kg per week justify larger baler specifications and direct buyer relationships that produce better per-tonne pricing.
Yes. Transporting manufacturing plastic film waste from your premises to a recycling facility or buyer requires a registered waste carrier licence if you are using your own vehicle or a third-party carrier. The carrier must be registered with the Environment Agency (in England) or the appropriate regulator in your devolved nation. If the film buyer arranges collection using their own vehicle, the buyer’s carrier registration covers the transport. Confirm carrier registration before any waste film leaves your premises with a third party.
Recycled plastic film for food contact applications is subject to additional regulatory requirements under UK food contact materials legislation. The recycled material must come from a dedicated food-contact approved recycling process and meet migration limits for substances that might transfer from the plastic to food. Standard manufacturing film recyclate from a general film recycler is typically not approved for food contact use. If your manufacturing operation is considering closing the loop on film recyclate back into food contact applications, consult with a food contact materials specialist before committing to a supply chain design.
