High-Moisture, Low-Bulk Film? See How Ag Film, Stretch Wrap & Bags Turn Into Premium Pellets

Wet, fluffy film scrap is every recycler’s nightmare. Genius Machinery’s squeeze-dry pelletizing line flips that nightmare on its head—wringing out water, densifying feed, and turning the industry’s hardest-to-handle materials into high-value pellets. To understand how Genius cracks the code, we first need to see why these films are so difficult in the first place.

High-Moisture, Low-Bulk Film? See How Ag Film, Stretch Wrap & Bags Turn Into Premium Pellets


Why These Materials Matter


Moisture and low bulk density drive up energy, labour, and reject rates—yet each film type poses its own twist:

  • Agricultural film arrives caked in soil and water—up to 50% moisture.
  • Warehouse stretch-wrap is thin, static-laden, and “air-rich,” so it bridges in hoppers.
  • Post-consumer shopping bags come baled, inconsistent, and often contaminated with organics.

Steam flashes, feeders choke, and pellets blister. Knowing the pain points, let’s see the engineering that removes them.

Adaptive Recycling Machines for Diverse Waste


Genius built one adaptive platform to conquer wildly different feedstocks:

Key Feature How It Works Why It Matters
Adjustable Squeeze Force PLC-controlled hydraulic rams tailor pressure to film thickness. Handles thin LLDPE wrap or thick silage film without change-overs.
Vacuum Double Degassing Two vent zones strip volatiles, inks, and organics. Protects melt flow and odour—critical for food-grade uses.
Variable-Pitch Screw Tapers flight depth to normalise bulk density. Prevents surging when density jumps after squeeze drying.

Technology is great, but proof on the plant floor is better—so let’s follow three converters who put it to work.


Field Story #1 – Silage Film in Northern Spain


“From Mud-Laden Rolls to High-Quality Recycled Pellets”

  • Starting Point – Co-op collected 18 t /day of LDPE silage wrap at 28 % moisture; legacy line rejected 25 % as wet fluff.
  • Intervention – Installed a 700 kg/h squeeze-dry line with a Dual-Piston Filter.
  • Outcome – Moisture ≤ 1 % on the first pass, IV preserved, qualified for blown-film extrusion; landfill diversion 4000 t / yr, energy cost per kg down 27%.


Plant Manager: “We used to pre-dry for eight hours—now we start the line at 7 a.m. and ship pellets after lunch.”


Having tamed mud-soaked ag film, let’s see how the same line tackles the opposite extreme: feather-light stretch wrap that refuses to flow.


Field Story #2 – Logistics Stretch-Wrap in Central Mexico


“Beating Bridging and Boosting Throughput”

  • Starting Point – Thin LLDPE stretch-wrap (bulk density < 0.05 g/cm³) rat-holed in the shredder feed box, forcing manual poking.
  • Intervention – Added a squeeze-dry module upstream of the plant’s existing extruder; retrofit completed in five days.
  • Outcome – Bulk density up , line speed from 450 → 650 kg/h with the same motor load, zero de-bridging labour, ROI in 11 months.

Thin wrap solved, the final test is the dirtiest: mixed shopping bags full of labels, organics, and ink.


Field Story #3 – Post-Consumer Bags in the US Midwest


“Closing the Loop for a National Retailer”

  • Starting Point – Bales of LDPE/LLDPE bags at 18 % moisture, 4 % contaminants; retailer pledged 30 % recycled content in house-brand bags.
  • Intervention – Full squeeze-dry pelletizing cell plus Metal Detector for contamination control.
  • Outcome – > 99 % density uniformity, moisture ≤ 0.8 %, film passed dart-drop & haze specs, Scope-3 CO₂e down 3,700 t / yr vs. virgin resin.

At-a-Glance Specs


With real-world wins in mind, here’s a quick look at the line’s key specs to help you gauge fit and footprint.

Parameter Value Notes
Throughput 300 – 1,000 kg/h LDPE/LLDPE film ≤ 50% moisture
Specific Energy ≈ 0.27 kWh/kg Internal test data
Line Length ≈ 14 m 40 % shorter than compactor + extruder setups
Power Supply 220-480 V, 50/60 Hz Global-ready electrical package
Control System Siemens PLC + cloud gateway with programming, data logging, and error tracking Live OEE and torque dashboard; CO₂e tracking available as an optional upgrade


These numbers give you a first sizing pass; a material test will confirm exact throughput and energy for your resin mix.

Key Takeaways from the Case Studies


From mud-soaked ag film to wispy stretch wrap and mixed post-consumer bags, one constant emerges: the squeeze-dry line adapts on the fly, delivering

  • High quality pellet
  • Higher bulk density—stable screw loading, higher throughput.
  • Double-digit energy savings—and payback in under 18 months.

If those numbers sound compelling, the next step is simple—let the data speak for your own scrap stream.
