Agricultural Film Recycling Machinery Suppliers
Source agricultural film recycling machinery from verified B2B manufacturers on Towobo. Agricultural plastic film — mulch film, silage film, tunnel film, and greenhouse film — is one of the largest and most difficult-to-recycle plastic waste streams globally. Processing heavily soil-contaminated agricultural film into clean recycled PE pellets requires specialised machinery capable of handling high contamination loads while producing commercially viable output. This guide covers the specific processing challenges of agricultural film and what to look for in a machinery supplier.

Agricultural plastic film is primarily LDPE or LLDPE (mulch film and greenhouse film) and LDPE or LLDPE/HDPE blends (silage stretch film). The key challenges that make agricultural film more difficult to recycle than industrial or packaging film are: high soil and sand content — mulch film used in the soil can carry 30–60% contamination by weight; wet and degraded condition — outdoor-weathered film is UV-degraded and brittle, generating more fines during size reduction; tangling — film pieces are long and prone to wrapping; very low bulk density — even after shredding, agricultural film flake is extremely light and difficult to convey and process in equipment designed for rigid plastic. Agricultural film recycling lines address these challenges through: a pre-cleaning trommel or drum washer to remove loose soil before size reduction; a wet granulator or film-specific shredder for size reduction in water; multiple friction washing stages with high water volumes; a float-tank for density separation; high-capacity centrifugal dewatering; thermal drying; and a pelletising extruder with a fine melt filtration system to remove residual mineral contamination.
Line configuration and throughput for agricultural film
Agricultural film washing lines are designed around the specific contamination level and film type. A line designed for lightly contaminated greenhouse or tunnel film will be insufficient for heavily soil-contaminated field mulch film. The critical stages are: pre-washing (trommel or drum) to remove loose soil — this stage alone may remove 20–40% of the input weight as mud and debris; wet size reduction — cutting film in water to prevent tangling and dust generation; multiple friction wash stages — typically 2–3 stages for heavily contaminated input; large-volume float separation tank — to separate residual soil and mineral contamination that sinks from floating PE film; high-capacity centrifugal dryer — sized for the very low bulk density of film flake (typically 4–8x the dryer volume capacity compared to a rigid plastic line of the same throughput in kg/hour); thermal drying; and an extruder with fine screen packs and a screen changer for pelletising. Water consumption is very high for agricultural film — 15–25 m³ per tonne of plastic processed is not unusual. A closed-loop water treatment system is essential.
Frequently asked questions
What is the typical output specification for recycled agricultural film pellets?
Recycled PE pellets from agricultural film typically achieve contamination levels of 300–800 ppm, moisture below 0.5%, and variable colour (grey to black depending on soil contamination and processing). These pellets are used in refuse sacks, construction sheeting, drainage pipe coatings, and other non-food non-critical film applications. Achieving the contamination levels required for printing-grade film or food-adjacent packaging from agricultural film input is technically challenging and typically requires additional NIR sorting or sorting to clean silage or greenhouse film fractions.
Is it economically viable to recycle heavily contaminated mulch film?
Economic viability depends on local market conditions — the cost of input film (including collection and transport), the value of the recycled pellet output, operating costs (energy, water, labour, maintenance), and available gate fees or incentives for waste processing. We cannot quote specific figures. Agricultural film recycling is commercially established in parts of Europe (particularly Spain, Italy, and France where mulch film use is high and recycling infrastructure is supported by producer responsibility regulations) and is growing in China. The economic case varies significantly by region and market conditions.
Does agricultural film need to be pre-sorted before the washing line?
At minimum, metal contamination (irrigation fittings, wire, plant ties) should be removed by magnet and manual inspection before the shredder. Some operations also separate different film types (mulch film from silage film from greenhouse film) before processing, as different films have different contamination levels and the washing line may need different settings for each. The more pre-sorting is done before the washing line, the better and more consistent the output quality.
How do I evaluate an agricultural film recycling machinery supplier?
Request: a process description specifically for your agricultural film type and contamination level; a list of operating reference lines processing similar material; achievable output quality data (contamination level, moisture) from reference sites; water consumption per tonne of input; power consumption per tonne of output; a layout drawing for the full line; and a commissioning and training plan. If possible, visit a reference site or request video of the line processing material comparable to yours. A supplier who cannot provide operating references for agricultural film processing specifically should not be trusted with the significant investment a complete agricultural film line represents.
