Waste PP Film/Bags Plastic Washing Line

Plastic bags, woven sacks and jumbo bags pile up fast in packaging plants, factories and collection yards. Most of this polypropylene waste arrives dirty. It carries sand, soil, labels, glue and product residue. If you pelletize it without proper cleaning, the pellets are weak, discolored and hard to sell.
A Waste PP Film/Bags Plastic Washing Line solves this problem. It crushes the material, washes out the dirt, removes the water and dries the flakes. The result is clean plastic pieces that are ready for storage or for the granulation process. Mooge builds this line in three standard models, from 300 kg/h to 1000 kg/h input capacity.
This guide explains how the line works, which materials it handles, how to read the technical data, and what to check before you ask suppliers for a quotation.

What Is a PP Film & Woven Bag Plastic Washing Line?

A PP film and woven bag plastic washing line is a group of connected machines that turns dirty polypropylene waste into clean, dry plastic pieces. It is built for soft, light material such as bags and films, which behaves differently from rigid plastic in a washing system.
The line performs five main jobs:

• Crushes bags and films into small, even pieces
• Removes surface dirt through high-speed friction
• Separates sand, stones and other heavy waste by flotation
• Removes water with a centrifuge
• Dries the pieces with hot air to a moisture content below 5%

Mooge designs the ME-Series line for both industrial and post-consumer plastic waste. Input capacity ranges from 300 to 1000 kg/h, depending on the model.
 

PP Film & Woven Bag Washing Line Process Flow, Step by Step

Every project is arranged around the buyer's factory area and final product needs. The standard flow follows these steps:

1. Feeding. A rubber conveyor belt carries the waste material between the machines and into the line.
2. Metal detection. A semi-auto metal detector finds ferrous and non-ferrous metal, which protects the crusher and later equipment.
3. Crushing. A crusher machine with water cuts large bags and films into uniform pieces.
4. Friction washing. A friction washer loader machine scrubs the pieces at high speed and removes soil, sand, labels and other surface dirt.
5. Sink-float washing. A sink-float washing tank separates floating plastic from heavy contaminants. Mooge suggests two tanks in series for a cleaner result.
6. Hot washing and rinsing. Optional hot washing and a clean-water rinse remove stubborn impurities and chemical residue.
7. Dewatering. A centrifuge dewatering machine removes excess water by centrifugal force.
8. Drying. A hot air dryer brings the moisture content below 5%.
9. Storage. A packing silo holds the dry pieces before packing or pelletizing.

A control panel runs and protects the whole line. A water circulator system filters and reuses the process water.

Waste PP Bags We Can Recycle: Woven Bags, Jumbo Bags, Sacks & Films

The ME-Series line processes the following waste PP plastic:

• PP woven bags and woven sacks
• PP jumbo bags
• PP films
• Other industrial and post-consumer plastic

Contamination changes from one source to another. Used woven sacks often hold sand, dust and product residue. Printed bags and labeled films add ink and adhesive. Before you choose a configuration, send your supplier clear photos or a sample of your material, and describe how dirty it is. This helps the engineers decide how many washing stages you need.
If you also recycle polyethylene, Mooge offers a separate Waste PE HDPE LDPE Film/Bags Plastic Washing Line for LDPE and HDPE film.

Hot washing is optional on all three models. The line can also be arranged to fit your factory area and final product needs, so treat these figures as a starting point. Your final layout and power data should come from the technical offer.

Key Machines in Our PP Woven Bag Recycling Washing Line

Each machine has a clear role. Knowing them helps you compare offers from different suppliers.

• Rubber Conveyor Belt: moves material between stages. It uses durable rubber, lasts long and needs little maintenance.
• Semi-auto Metal Detector: detects metal contaminants before they damage the crusher or the downstream machines.
• Crusher Machine With Water: uses high-performance blades to cut plastic into uniform pieces while saving energy.
• Friction Washer Loader Machine: conveys the pieces and cleans them at high speed.
• Sink-float Washing Tank: uses water flotation to remove sand, stones and other heavy impurities.
• Centrifuge Dewatering Machine: cuts the water content before drying, which improves drying efficiency and lowers energy use.
• Hot Air Dryer: circulates hot air to dry the pieces thoroughly.
• Packing Silo: buffers the dry material so production and packing run smoothly.
• Control Panel: combines start/stop, parameter settings and safety protection.
• Water Circulator System: lowers fresh water use and operating cost.

How Does a PP Film Washing Line Remove Sand, Soil & Labels?

 
No single machine cleans PP film and bags. The line removes dirt in stages, and each stage handles a different type of contamination.

Why a Waste PP Film/Bags Plastic Washing Line Needs Multi-Stage Cleaning

Woven bags and films trap dirt in folds and fibers. One wash would leave residue behind. A multi-stage Waste PP Film/Bags Plastic Washing Line attacks the dirt step by step, so the final pieces are cleaner.

Friction Washing

The friction washer loader machine rubs the pieces at high speed. This loosens soil, sand and labels from the surface and prepares the material for the next stage.

Sink-Float Separation

PP floats on water, while sand and stones sink. The sink-float washing tank uses this difference to split them. Two tanks in series give a more thorough result.

Hot Washing and Rinsing

For stubborn impurities and chemical residue, the optional hot washing step and a final clean-water rinse give extra cleaning power. Choose this option when your waste carries oil, glue or other sticky residue.

Material Before and After Washing: Clean PP Flakes Quality

The input is dirty PP jumbo bags and woven bags. The output is washed PP bag pieces that are clean, dry and ready for the next step. You can see the before and after photos on the product page.
When you check the quality of washed pieces, look at these points:

• Cleanliness: no visible sand, soil, labels or other heavy contaminants
• Moisture: below 5% after hot air drying
• Size: uniform pieces from the crusher, which feed the next machine evenly
• Consistency: the same quality from batch to batch

Clean, dry pieces can go to storage or directly to pelletizing. If you plan to make granules, look at Mooge's Plastic Pelletizing Line to build a complete recycling process.

How Much Does a PP Film & Woven Bag Washing Line Cost?

The price depends on the project, so a fixed number would mislead you. These factors change the cost most:

• Model and capacity (ME-300, ME-500 or ME-1000)
• Hot washing option
• Number of sink-float washing tanks
• Material type and contamination level
• Power supply and local voltage
• Factory layout and available area
• Extra equipment, such as a shredder or a pelletizing line

To get an accurate quotation, send your supplier this information: material type and photos, contamination level, target capacity, final product use, voltage, and factory space. A clear request leads to a faster and more accurate offer.

Water Consumption & Water Recycling System for PP Film Washing

Washing needs water, so water supply matters in your planning. Standard water supply is 6-8 m³/hr for the ME-300, 8-10 m³/hr for the ME-500 and 15-20 m³/hr for the ME-1000.
The water circulator system filters process water and sends it back into the washing stages. This reduces fresh water use and operating cost, and it supports cleaner production. Check your local water and wastewater rules early, because requirements differ by country and region.

PP Film Washing Line vs. PE Film Washing Line: What’s the Difference?

Both lines clean plastic film and bags, and the basic machine flow is similar. The difference lies in the material and the contamination.

• Material: PP lines handle woven bags, woven sacks, jumbo bags and PP film. PE lines handle LDPE and HDPE film and bags.
• Contamination: Woven PP bags often trap sand, dust and product residue in the weave. PE film often carries different dirt, depending on its source.
• Flotation: PP and PE both float in water. The sink-float tank separates them from sand and stones, not from each other.
• Sorting: If your waste is a PP and PE mix, tell the supplier the ratio. It affects the line design and the quality of the output.

You can review both options on Mooge's PE/PP film and bags pages and choose the line that matches your main material.

How to Choose the Right PP Bag Washing Line Capacity for Your Factory

Start with your real waste supply. Multiply the line capacity by your daily working hours. For example, a 500 kg/h line running 8 hours handles 4,000 kg of input per day. Then check these points:

• Waste supply: Can you feed the line steadily? A line that waits for material wastes money.
• Space: The ME-300 and ME-500 need about 40m×4m×5m. The ME-1000 needs about 55m×6m×6m.
• Power and water: Confirm that your site can supply the installed power and water in the table.
• Downstream equipment: Match the washing capacity to your pelletizing line.
• Growth: Think about future volume before you pick the model.

If your waste arrives as large, bulky bales, a Plastic Shredder Machine can help prepare the material before washing. Ask the engineers whether your material needs this step.
