Woven Bag Washing Line for PP Bags, FIBC Bulk Bags & Raffia: US-Ready
Woven bags and super sacks break standard film lines — they bridge in feeders, carry sand deep in the weave, and tangle everything downstream. This line is built for PP woven bags, FIBC bulk bags, raffia sacks, and mixed film: anti-bridging feeding, aggressive friction washing for sand and soil, sink-float separation, and dewatering plus an optional squeezer stage for pelletizer-ready flakes. Configured for North American plants: 480V 3-phase power, UL 508A panel option, US spare-parts support, and on-site commissioning.
A Woven Bag 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 (shredder blades, granulator knives, screens, seals) 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.
Why Woven Bags Break Standard Film Lines
Woven PP behaves nothing like flat film. Buyers who run super sacks through a standard film washer learn this the expensive way.
What Shows Up in the Bale
- FIBC bulk bags (super sacks) — 1–2 ton bags from agriculture, chemicals, and food; liners, straps, and dust bags attached.
- PP woven sacks — fertilizer, feed, and seed bags carrying sand and soil ground deep into the weave.
- Raffia & fabric offcuts — long, stringy material that wraps shafts and blinds screens.
- Mixed film + fabric — packaging streams where film, woven scraps, and nonwovens arrive together.
How the Line Handles It
- Anti-bridging feeding — bale opener plus forced feeding keeps bulky woven material moving; no operator with a stick.
- Heavy-duty shredding first — cuts whole super sacks and straps down before granulation, so nothing wraps.
- Double friction washing — scrubs sand and soil out of the weave; staged sink-float drops the heavy fraction.
- Squeezer option — mechanically presses washed flakes to low moisture and higher bulk density for the pelletizer.
Working Principle & Process Flow
Film and fabric-like plastics require stable feeding and stronger washing. This line emphasizes robust size reduction, friction washing, and efficient dewatering to support downstream pelletizing.
-
Bale Opening & Forced Feeding
Opens bales and force-feeds bulky woven material — anti-bridging design keeps super sacks and raffia flowing without manual poking.
-
Heavy-Duty Shredding
Pre-cuts whole FIBC bags, straps, and liners into manageable pieces; handles stringy raffia without wrapping.
-
Wet Granulation
Water-assisted cutting reduces friction, starts the cleaning process, and produces uniform flakes for washing.
-
Sink-Float Separation
Staged tanks drop sand, grit, and heavy contamination while PP/PE flakes float on to continued washing.
-
Double Friction Washing
Two high-speed friction washers in series scrub sand and soil out of the weave — the step standard film lines skip.
-
Dewatering + Thermal Drying
Centrifugal dewatering plus hot-air drying brings moisture down for stable pelletizer feeding.
-
Optional Squeezer Stage
For washed film-heavy streams, a screw-press squeezer further cuts moisture and densifies flakes before pelletizing.
Dedicated Woven Line vs. Standard Film Setup
An honest comparison — including where a standard film line is enough and where it isn't.
| Item | Standard Film Line | ASG Woven & FIBC Line |
|---|---|---|
| Feeding | Gravity/belt feed; woven bags bridge and stall | Bale opener + forced feeding; anti-bridging design for bulky woven material |
| Size reduction | Single shredder; straps and raffia wrap shafts | Heavy-duty shredder first, then wet granulation — stringy material handled |
| Sand/soil removal | Single wash pass; sand stays in the weave | Double friction washers + staged sink-float targeting sand in woven fabric |
| Moisture before pelletizing | Dewatering only; film-heavy streams run wet | Dewatering + thermal drying; optional squeezer stage for film-heavy streams |
| Honest fit | Running clean post-industrial film only? Our PP/PE film washing line is the leaner, cheaper answer. Woven bags, super sacks, or sand-heavy streams are where the dedicated woven line earns its price. | |
Capacity Tiers & Investment Guide
Three standard configurations cover most US woven-bag and film projects. Final pricing depends on contamination level, wash intensity, and drying configuration — send your bag spec and we’ll price your exact setup.
| Compact — 500 kg/h (1,100 lbs/hr) | Entry point for regional collectors and first-time washers. Single friction washer standard; squeezer optional. |
|---|---|
| Mid-size — 1,000 kg/h (2,200 lbs/hr) | The most quoted tier for independent US reclaimers. Double friction washing; staged sink-float; water recirculation included. |
| Commercial — 2,000 kg/h (4,400 lbs/hr) | Continuous-operation plants feeding pelletizing lines. Full wash train, thermal drying, and squeezer stage options. |
What moves the price: single vs. double friction washing, shredder duty level, sink-float stage count, drying level (dewatering only vs. thermal + squeezer), and automation. Every proposal itemizes these so you can see exactly what you’re paying for — and what you can defer.
What It Costs to Run
Buyers who ignore operating cost buy twice. These are the line items to budget before you sign.
Power
Woven lines draw more power than flat-film lines — heavy-duty shredding and double friction washing are the big loads. We provide a connected-load schedule per configuration in the proposal.
Water
Makeup water with recirculation and filtration. Sand-heavy ag bags consume more filtration media; cleaner industrial sacks consume less.
Wear Parts
Shredder blades and granulator knives wear faster on sand-heavy streams — that's exactly what the double wash train protects against. Kits priced per line, stocked in the US.
Labor
3–4 operators per shift depending on tier and presort level. Strap and liner removal at intake is the main manual task on FIBC streams.
What We Need From You for a Real Number
A "price for the line" without your feedstock is a guess. Send these five things and the proposal comes back itemized.
-
Bag photos or video
Woven sacks, super sacks, or mixed film — a 30-second phone video of typical incoming material tells us more than a spec sheet.
-
Contamination level
Sand/soil load, liners, straps, labels, chemical residue — the single biggest driver of wash-train sizing.
-
Target capacity
kg/h or lbs/hr of clean flake output — not input. We size the wash train to output.
-
End market
Pelletizing in-house or selling washed flakes? The moisture and cleanliness spec differs.
-
Site utilities
Available power (amps at 480V), water supply, and floor space with ceiling height.
