What are pp woven bags?  Here is the complete guide to pp woven bags you need to know!

Pp Woven bags are quite popular products on the market with many different uses. Follow this article, let’s learn more about this new type of environmentally friendly packaging. All you want to know about pp woven bags is here!

What is pp woven bag?

PP woven bag is made from polypropylene resin. Polypropylene, which is also known as PP for a short name, is one kind of thermoplastic resin material. During our production process, it is first made into a plastic film, then drawn into flat tapes. And then the polypropylene tape will be woven in two directions (warp and weft) to create a light, but strong and heavy-duty fabric, which will be used as the main material for packaging making, hence the name woven package.

    1. Woven

Woven, or weaving is a method by many threads or tapes woven in two directions (warp and weft), to form a fabric for plastic industry needs.

In the plastic woven industry, with a plastic film is drawn into filaments, woven into fabric/sheet/cloth. It can be into a tarpaulin, woven bags, container bags, tons of bags, geotextile fabric, color of the cloth and so on.

    2. Woven polypropylene

Polypropylene, which is also known as PP for short name, is one kind of thermoplastic resin material that produced by the polymerization of propylene. Thus, woven polypropylene is polypropylene strips/threads that have been woven in two directions (warp and weft) to creat a light, but strong and heavy duty material.

What’s the types of pp woven bags?

There are different types of packaging according to different materials. Therefore, there are also different types of pp woven bags.

PP Woven Bag with Bottoms

The bag has 1 layer of PP woven fabric coated with PP bonding plastic. The two ends of the bag are covered by rectangular PP adhesive when the material is closed, it will be in the form of a block, with an inlet valve at the corner, the valve has a 1-way principle, self-closing.

What’s the production process of pp woven bags?

Tape Extrusion

Tape extrusion is the most critical process of the woven industry since the quality of the tape has a direct impact on the quality of the packaging. During the extrusion stage the mixture will be heated to a specific temperature for plasticization, and then extruded in a flat sheet and cooled in a water tank. After the initial cooling, the flat sheet will then be split into strips by high-precision cutters. After the splitting, the flat tape will then be heated, stretched, and cool multiple times to achieve the required linear tensile strength.

Circular weaving

Woven packaging is made from tubular fabric which is weaved by a circular weaving machine using PP flat tape. Shuttles in the circular weaving machine weave the tape in the weft and warp direction to form the woven fabric in a tubular structure.

Rotogravure printing

To achieve the aesthetic and advertisement property of our packaging, the woven package will be laminated with a layer of BOPP film above the woven fabric. The Biaxially Oriented Polypropylene (BOPP) film is printed using a rotogravure printing machine. And based on customer requirements, another background layer of pearl white or aluminized film can be added between BOPP film and the woven fabric.

Bag Making

Bag making mainly consists of 3 major processes: lamination, side gusset, and bag making. Lamination is one of the most critical processes for woven packaging making. BOPP film and woven fabric are laminated using a mixture of PP and LDPE. It’s melted and then laminated between two layers to form a bond. Temperature control and cooling is the key control point for a desirable bonding.

However, there are the reasons why more and more business chooses pp woven bag. The Australian government introduced a new environmental protection policy in 2018, and officially began to stipulate that all enterprises should focus on energy conservation and environmental protection. We strongly advocate the Increase use of recycled material and build demand and markets for recycled products. From July 1st, all major shopping malls and supermarkets in Australia are restricted to provide plastic bags. From then on, all businesses have begun to find solutions for environmentally friendly packaging.

So you may wondering is woven polypropylene an eco-friendly material?

- Yes, it’s an eco-friendly fabric. It can be melted down, recycled and made into other products. Besides, they last long enough and can be used many times to reduce your demand from single-use products.

When it comes to creating your very own custom reusable bags, you want something durable and eco-friendly, but when faced with your options it can be hard to make a decision. If you’ve narrowed down your options to recycled plastic, that’s a start, but you still need to make the call between woven vs. non-woven polypropylene bags.

So Whats the different between PP woven bags and Non pp woven bags?

Woven Polypropylene

Woven polypropylene is made when recycled plastic is stretched into long threads. These threads are then woven in a way similar to how cotton and other fabrics are woven. This woven construction lends the fabric lots of durability.

Non-Woven Polypropylene

Non-woven polypropylene is also made using recycled plastic stretched into threads, but those threads are bonded together. The resulting fabric is also very durable, it also has a smoother surface.

Both woven and non woven polypropylene bags are made from recycled plastic. The difference is in how they are built. To make woven polypropylene plastic threads are woven together in a more traditional manufacturing process to create a durable material. To create non woven polypropylene plastic fibers are bonded together. In both instances the fabric is durable, and when used to make reusable bags they will deliver years of dependable use.

Application of pp woven bags

  • Agricultural product packaging: PP woven bags are largely used in storing and transporting agricultural products such as aquatic products, feeds, fruits, vegetables, etc. PP woven bags used in the agricultural industry typically include feed PP woven bags, chemical PP woven bags, fertilizer PP woven bags, vegetable weaved bags, and fruit mesh bags.
  • Food packaging: PP woven bags are increasingly used to pack food. Common food woven bags include rice PP weaved bags, flour PP woven bags, maize woven bags, etc.
  • Geotechnical engineering: PP woven fabrics are extensively used in the construction of irrigation works, roads, railways, ports, mines, buildings, and more. Having the functions of filtering, draining, isolation, and anti-seepage, PP woven fabrics are one of the most popular geosynthetics.
  • Tourism and transport: Temporary tents, sunshades, and various travel bags can be made with PP woven fabrics. In addition, plastic woven fabrics can also be used as fences and screens during construction.
  • Daily necessities: PP woven bags are almost used by everyone, whether workers, farmers or cargo agents, etc. You can find plastic woven products (such as shopping bags, logistics bags, etc.) in stores, warehouses, and houses, nearly everywhere.
  • Flood control products: Woven bags play an important role in reducing or preventing the detrimental effects of floodwaters. They are widely used in the construction of dams, river banks, roads, and railways. Woven polypropylene sandbags are widely used all over the world.
  • The special woven bags: The special woven bags also are used to serve some special purposes. For example, UV-resistant woven bags have UV protection and anti-aging function, allowing them a longer lifespan in the sunlight. A woven polypropylene tube with UV protection can be used for earthbag buildings.


With the gradual strengthening of people’s awareness of environmental protection, environmentally friendly products have become a new challenge faced by various enterprises.  For packaging products of the same weight, PP woven bags can be lighter than ordinary plastic packaging, use less plastic, and meet the environmental protection trend of lightweight packaging. Thus,  pp woven bags are definitely your best partner for environmental protection.
