PP/PE Film Washing Line for Clean Flakes and Stable Pelletizing
Turn dirty post-consumer and post-industrial plastic film — agricultural film, stretch and shrink packaging film, factory trim — into clean, low-moisture flakes that feed a pelletizer without surging, smoking, or screen-pack changes every hour. Staged washing, friction scrubbing, and mechanical-plus-thermal drying, configured for North American plants: 480V 3-phase power, UL 508A panel option, US spare-parts support, and on-site commissioning.
A Film Washing Line Configured for US Operating Reality
Buying recycling equipment from overseas raises the same five questions on every US project. We answer them in the proposal — not after the deposit.
480V 3-Phase Power
Motors, heaters, and controls specified for 480V/60Hz 3-phase — the US industrial standard — instead of a generic "customer voltage" footnote.
UL 508A Panel Option
Control panels available built to UL 508A industrial control panel standards for straightforward inspection and insurance sign-off.
US Spare-Parts Support
Wear-part kits (blades, screens, seals, belts) defined per line, with stateside stocking so a worn screen doesn't idle your plant for six weeks.
On-Site Commissioning
English-speaking engineers for installation supervision, commissioning, and operator training — plus remote diagnostics after handover.
Import & Duty Guidance
We walk through landed-cost planning with you — freight, Section 301 duty considerations, and documentation — before you commit.
Dual-Unit Documentation
Layouts, manuals, and spec sheets in kg/h and lbs/hr, metric and imperial dimensions — written for the crew that will actually run the line.
Designed Around Real Film Contamination
Film washing performance is decided by the dirt load, not the brochure. The line is configured for what actually arrives on the truck.
What Shows Up in the Bale
- Agricultural film — greenhouse and mulch film carrying 20–40% sand, soil, and organic matter by weight.
- Stretch & shrink film — labels, tape, and strapping mixed into distribution-center bales.
- Post-industrial trim — cleaner, but static-prone and prone to bridging in the feed hopper.
- Moisture on arrival — rain-soaked outdoor bales can enter at 15–30% moisture before washing even starts.
How the Line Handles It
- Bale opening + metered feeding smooths bulky, low-density film into a steady stream — no bridging, no surging.
- Staged float-sink tanks pull sand and heavy contamination out before it reaches the friction washer.
- High-speed friction washing scrubs soil and organics off film surfaces that tanks alone can't clean.
- Mechanical dewatering + thermal drying bring moisture down to pelletizer-ready levels regardless of incoming rain.
How a Plastic Film Washing Line Works, Stage by Stage
Film is low-density, high-surface-area material — it floats, bridges, and wraps. The line is sequenced to control each of those behaviors in order.
-
Bale Opening & Feeding
Baled film is opened and metered onto the conveyor. Controlled feed rate is the single biggest factor in stable downstream throughput — a starved crusher and a choked crusher both kill output.
-
Wet Crushing / Granulation
Film is size-reduced under water spray. Wet cutting keeps blades cooler, suppresses dust, and starts pre-washing in the same pass.
-
Float-Sink Separation Tanks
Crushed film floats; sand, soil, stones, and heavy labels sink. Staged tanks with screw conveyors move film forward while contamination drops out — this is where agricultural film loses most of its dirt load.
-
Friction Washing
High-speed rotors scrub film surfaces at 800–1,000 rpm, stripping the soil film and organic residues that float tanks leave behind. This stage decides final pellet appearance.
-
Rinsing (Optional Second Stage)
For heavily contaminated agricultural or silage film, a second rinse with clean water prevents re-deposition of fines before drying.
-
Mechanical Dewatering
Centrifugal dryers spin surface water off the flakes, typically bringing moisture from 25–30% down to 5–8% without heat.
-
Thermal Drying
Hot-air drying takes flakes below 3–5% moisture — the level a pelletizer needs for stable extrusion without steam surging or excessive degassing.
-
Silo / Buffer Storage
Dried flakes are conveyed to a storage silo that buffers the pelletizer, decoupling washing throughput from extrusion rate.
Capacity Tiers: Match the Line to Your Film Stream
Film lines are sized by washed, dried output — not raw bale weight in. Agricultural film at 30% dirt yields far less clean flake per bale than factory trim.
| Tier | Output | Typical feedstock | Best for |
|---|---|---|---|
| FWL-500 | 500 kg/h (1,100 lbs/hr) | Post-industrial trim, clean stretch film | Startups and in-house scrap recycling |
| FWL-1000 | 1,000 kg/h (2,200 lbs/hr) | Mixed packaging film, distribution bales | Regional recyclers, 1–2 shift operation |
| FWL-2000 | 2,000 kg/h (4,400 lbs/hr) | Agricultural film, heavier contamination | Ag-film specialists, multi-shift plants |
| FWL-3000 | 3,000 kg/h (6,600 lbs/hr) | High-volume mixed film streams | Large MRFs and pellet producers |
What It Costs to Run: Water, Power, Labor
Film washing is a water-and-power business. We size utilities per project, but these are the ranges US buyers should budget around.
Water Consumption
With recirculation and filtration, fresh-water makeup runs roughly 2–4 m³ per ton of clean flake for packaging film, 4–8 m³/ton for dirty agricultural film. Closed-loop filtration cuts discharge and municipal surcharges.
Power Draw
A 1,000 kg/h line typically draws 250–350 kW installed (crushers, friction washers, dryers, thermal drying). All motors and heaters specified for 480V/60Hz 3-phase.
Labor
One operator per shift for feeding oversight and QC at the dry-flake silo; automated lines add remote monitoring instead of headcount. Bale handling is the main labor variable.
Hot Wash vs. Cold Wash: Which Does Your Film Need?
The single most common pre-quote question. The honest answer depends on your contamination, not your budget.
Cold Wash Line
Best for: post-industrial trim, relatively clean stretch film, and in-house scrap where oil and organics are minimal.
Trade-offs: lower capex and energy use, but grease, oils, and heavy organics largely stay on the flake — limiting you to darker, lower-value pellet outlets.
Hot Wash Line
Best for: agricultural film, silage film, food-contaminated packaging film, and any project selling into higher-spec pellet markets.
Trade-offs: higher capex (heated tanks, steam/boiler, caustic dosing) and energy use — repaid by access to cleaner flake and better pellet pricing.
Our rule of thumb: if your film carries soil, manure contact, or food oils — quote the hot-wash configuration. We'll confirm against your actual bale photos before finalizing.
ASG vs. Conventional Film Washing Lines
A clear, practical comparison that focuses on throughput stability, cleanliness, and operating cost.
| Item | ASG Line | Conventional Line |
|---|---|---|
| Feeding | Bale opening + metered feeding designed for low-density film; no bridging | Manual or gravity feed; frequent bridging and surging |
| Cleaning performance | Staged float-sink + high-speed friction washing; hot-wash modules for ag film | Single tank wash; soil film remains on flakes |
| Moisture control | Centrifugal dewatering + thermal drying to <3–5% for stable pelletizing | Mechanical drying only; 8–12% moisture causes extruder surging |
| Water management | Recirculation with filtration; 2–8 m³ fresh water per ton of flake | Once-through water; high municipal discharge costs |
| US readiness | 480V/60Hz, UL 508A panel option, stateside spares, on-site commissioning | Generic voltage, no UL path, spares shipped from overseas |
| Delivery & service | Turnkey support: layout, installation, commissioning, training, lifecycle service | Equipment-only delivery; commissioning at extra cost |

What Customers Value Most
Typical feedback we hear from film recycling projects after commissioning.
"The line runs steadily on mixed film. After tuning the washing stages, pellet quality improved and downtime dropped."
"Installation and start-up support was efficient. The team helped us ramp up quickly and train operators."
"We like the modular design. We started with a base line and expanded capacity later without rebuilding everything."
