- Available in different sizes and specifications.
- Can be manufactured with laminated or unlaminated surfaces.
- Ideal for printing product labels and brand information.
- Re-useable based on application and circumstance.
How Are PP Woven Bags Manufactured?
PP woven bags are made by a process that processes polypropylene raw material to make woven fabric and finally into the packaging bags.
This process is carried out by polymer extrusion, tape stretching, weaving, printing, cutting and stitching to obtain the specifications of the bags.
The main manufacturing stages include:
- Raw Material Selection: To determine the strength of fabric and application, the PP granules are chosen accordingly.
- Extrusion: Thin plastic sheets are produced by melting and processing the polypropylene granules.
- Tape Stretching: Narrow tapes of the sheets are stretched to improve their tensile properties.
- Weaving: To weave the PP tapes into PP woven fabric, circular weaving loom or flat weaving loom is used.
- Lamination (If Required): A coating or laminated layer can be applied to improve moisture resistance and provide additional surface protection.
- Printing: Details, logos, branding and other information is required can be printed on the fabric.
- Cutting and Stitching: Woven fabric is cut and stitched into the desired size and shape to create finished bags.
- Quality Inspection: End-products are inspected for size, stitching, fabric quality and more depending on the application.
What Are the Different Types of PP Woven Bags?
There are various constructions and configurations of PP woven bags to suit the different packaging needs.
Selection is based on the product packed, load capacity required, storage environment and transportation requirements.

What Are Woven Polypropylene Bags Used For?
Because of its woven material properties, a polypropylene woven bag is used in agriculture, food processing, construction, chemicals and all other industries where the packaged material needs to be strong enough and handled easily.
Some common applications include:
- Agriculture: Packaging of rice, wheat and grains, agricultural commodities and seeds.
- Food Processing: Packaging of flour, sugar, animal feed etc. suitable food products.
- Construction: Packaging of cement, sand and construction materials.
- Fertilizer Industry: Packing fertilizers and farm inputs.
- Chemical Industry: Packaging suitable industrial chemicals and raw materials.
- Industrial Packaging: Packaging for the storage and transport of a variety of solids.
The material of the bags, inks used for printing and manufacturing process should satisfy the applicable food-contact requirements for food-related applications.
What Is the Difference Between Laminated and Unlaminated PP Woven Bags?
Laminated PP woven bags versus unlaminated PP woven bags is that the unlaminated one does not have the “coating” or “protective” layer.
Laminated bags provide an extra moisture and external contaminant barrier while unlaminated bags are manufactured with the original woven fabric construction.
| Comparison | Laminated PP Woven Bags | Unlaminated PP Woven Bags |
|---|---|---|
| Construction | Woven fabric with an additional laminated layer | Woven polypropylene fabric |
| Moisture Protection | Better surface moisture protection | Limited moisture protection |
| Surface | Coated and smoother | Textured woven surface |
| Printing | Suitable for different printing requirements | Printing options depend on construction |
| Applications | Products requiring additional protection | General agricultural and industrial packaging |
Depending on the moisture sensitivity of the product, storage conditions and packaging specifications, the following options will be available:
Not all lamination makes all bags waterproof.
What Sizes and Capacities Are Available in PP Woven Bags?
The size and load capacity of PP woven bags depend on the products, filling machine and transportation.
Typical packaging specifications include 25 kg and 50 kg bags, the size and material of which will vary according to the use.
Important specifications to consider include:
- Bag length and width.
- Fabric GSM (grams per square metre).
- Tape denier and fabric construction.
- Required load-bearing capacity.
- Lamination requirements.
- Printing and branding requirements.
- Top and bottom stitching specifications.
- Filling and discharge requirements.
In the agricultural and industrial packaging, 25kg PP bags and 50kg PP woven bags are commonly used, for example.
The final size and strength, however, should only be confirmed by product specifications and application tests.
