Woven Bag & BOPP Film Washing Line for Raffia and Oriented PP Packaging Recycling
Built specifically for PP woven bags (raffia) and oriented PP packaging films such as BOPP, CPP, and IPP. This turnkey washing line removes heavy ink, labels, sand, and organics—delivering clean, low‑moisture flakes ready for stable downstream pelletising.
Typical capacities range from 500–3000 kg/h. We can add optional hot‑wash, stronger friction washing, and upgraded drying to match printed/laminated feedstock—turning loose or baled raffia and packaging film into reusable material.

Core Workflow at a Glance
A streamlined 3-stage approach ensures excellent cleanliness and low moisture—ideal for woven bags (raffia) and BOPP/CPP/IPP film recycling before pelletising.
-
Shredding / Wet Granulation Reduce film to uniform pieces to prevent tangles and enable consistent washing downstream.
-
Friction Washing + Separation Intensive friction removes labels, organics and dirt; sink-float separates by density.
-
Multi-stage Drying Centrifugal and thermal drying (or screw press) lowers moisture for stable pelletising.
Typical Feedstock: Woven Bags, BOPP, CPP & IPP
Built for flexible packaging and raffia streams where printed surfaces, organics, sand, and labels can impact output quality. We configure shredding, washing intensity, and drying to match your contamination profile and pelletising target.
- PP Woven Bags (Raffia / Woven Sacks)
Handles woven bags and raffia tapes from agriculture and industrial packaging. For anti-tangling pre-cutting, pair with a dedicated single-shaft shredder for film & raffia.
- BOPP Film (Printed / Laminated)
Configured for high-ink and adhesive residues using intensive friction washing and optional hot washing—helping deliver cleaner flakes for stable melt processing.
- CPP / IPP Packaging Films
Works with cast PP films and flexible packaging waste where fines and light contamination require precise separation and reliable multi-stage drying.

Why Raffia & BOPP Need Stronger Washing
Compared with general post‑consumer film, raffia woven bags and oriented PP packaging often carry heavier printing, adhesive residues, and embedded fines. We configure higher-intensity washing and drying so pelletising runs stable and output quality stays consistent.
-
Ink & Adhesive Residues Optional hot wash and stronger friction washing help reduce ink/adhesive carryover from printed and laminated packaging.
-
Sand, Organics & Fine Particles Sink–float separation + controlled rinsing remove embedded sand/organics that can cause black specks and wear.
-
Moisture Control Before Pelletising Upgraded dewatering (centrifugal / screw press) and drying reduce moisture swings that impact extrusion stability.
-
Configured for Your Packaging Stream We match pre‑cutting, washing intensity, and drying to your contamination profile—BOPP, CPP, IPP, or raffia sacks.

Working Principle: A Step-by-Step Guide
The entire plastic film washing line is intelligently controlled via a central electric control panel and cabinet, ensuring synchronised operation. Each piece of equipment is seamlessly connected using conveyors for smooth material flow.
- 1. Plastic Shredder: The initial crucial step is to cut film, PP woven bags (raffia), and BOPP/CPP/IPP packaging into smaller, manageable pieces (1–5 inches) to prevent tangling and blockages. For raffia streams, consider a purpose-built single-shaft shredder.
- 2. Plastic Granulator (Wet): Further reduces film size to 10–20 mm. Constant water injection serves as a pre‑treatment, partially cleaning the material.
- 3. Friction Washer: A high‑speed (≈1,000 RPM) unit that uses friction to dislodge stubborn contamination and break down paper into removable fibres.
- 4. Sink‑Float Separation Tank: Uses water to separate materials. PP/PE films float, while heavier contaminants like dirt, sand, and metals sink and are removed.
- 5. Centrifugal Dewatering: The first drying stage, using centrifugal force to remove a significant amount of water and save energy costs for thermal drying.
- 6. Screw Press Dewatering (Optional): An advanced option that squeezes water out via high pressure, potentially replacing both centrifugal and thermal drying stages.
- 7. Thermal Dryer: The film travels through stainless steel tubes with hot air to thoroughly dehydrate remaining moisture, ending in a cyclone separator to cool the film and remove fines.
- 8. Product Silo: A dedicated storage tank for the clean, dry pieces of plastic film before the final stage.
- 9. Plastic Pelletising Machine: The final, crucial step. A specialised water‑ring pelletising system processes the clean film into uniform, high‑quality plastic pellets.
Tip: Choose shredders when handling bulky bales and tough contaminants; opt for wet granulators when you want pre‑washing and tighter size control upfront.
Pre‑treatment: Shredder vs. Wet Granulator
Both approaches are effective. Your choice depends on feed form, contamination level, and downstream cleanliness targets.
-
Shredders Heavy‑duty, low‑speed tearing for bales and large films. Produces irregular pieces with low dust and noise — ideal as the first stage.
-
Crushers (Wet Granulators) High‑speed cutting that achieves tighter sizes and pre‑washing. Great for improving downstream washing efficiency early.
Drying Systems: Hitting Target Moisture
The goal before pelletising is consistently low moisture. Combine mechanical and thermal methods to reach stable output.
- Centrifugal Dewatering Rapidly removes surface water with low energy, preparing material for final drying.
- Screw Press (Optional) High‑pressure squeezing can replace centrifugal + thermal stages in some film applications.
- Thermal Drying Hot‑air tubes and cyclones bring moisture down to the level required for stable pelletising.

Frequently Asked Questions
This line is designed specifically for PP woven bags (raffia) and oriented PP packaging films such as BOPP, CPP, and IPP—including printed/laminated waste. We tailor pre‑treatment, washing intensity, and drying based on your contamination level and pelletising target. For mixed PP/PE post‑consumer film projects, please use our dedicated PP/PE Film Recycling Washing Line page.
Yes. We design the front end to prevent tangling by using a suitable shredder or wet granulator and stable conveying. For woven/raffia streams, we often recommend a dedicated single-shaft shredder as the first stage.
High-speed friction washing is the core for removing surface contamination, with optional hot washing and stronger rinsing when ink/adhesive residues are heavy. We also size the drying stage (centrifugal, screw press, and/or thermal drying) to hit your moisture target before pelletising.
The final output of our complete turnkey recycling line is high-quality, uniform plastic pellets. These pellets are clean, dry, and ready to be reintroduced into manufacturing processes to create new products.
Yes, absolutely. While our standard configurations range from 500kg/h to 3000kg/h, we specialize in providing custom-designed setups. We offer a complimentary solution design service to tailor a system with the specific machinery and capacity to meet your unique operational needs.
Long pieces of plastic film can easily tangle and clog conveyors and other rotary machines. The initial shredding step is crucial to cut the film into smaller, more manageable pieces, ensuring a smooth and efficient flow of material throughout the entire washing and pelletising line.
