PP Woven Bags - The Useful Guide

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!

PP woven bag is a durable, lightweight fabric that can make packaging. The polypropylene resin it’s made from first becomes plastic on the film and then gets drawn into flat tapes before being intricately intertwined together in order to create this strong yet lightweight product!

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.

Polypropylene is a strong but light material that can be used for anything from clothing to home furniture. It’s created by polymerizing propylene gas into threads which are then woven in two directions – warp and weft (the same way fabric gets thicker near where it was stretched).

Tape Extrusion

Extruding a mix of polymers and plastics at specific temperatures is the most critical process in producing quality packaging materials. During this stage, heated tape will be stretched to achieve linear tensile strengths with high precision cutters as it awaits further processing into strips for cooling before being split up once more by efficient machinery.

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 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 the film and the woven fabric.

Bag Making

Lamination is the most critical process for woven packaging making and it’s done using PP or LDPE to create a bond between two layers. It’s important that we have good temperature control, and cooling methods like air flow circulation systems which help decrease friction on machinery during production speeds so they don’t burn out!”.

However, there are the reasons why more and more business chooses pp woven bag. The UK 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. UK tax on plastic bags in 2015, and 5p charge on disposable bags to double to 10p.From then on, all businesses have begun to find solutions for environmentally friendly packaging.

Therefore, in this article，you’ll find the answer what’s the benefit of using pp woven bag and what’s the properties of pp woven bags!

Pp woven bags can be side gusseted to accommodate bulky items easily

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.

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.

The differences between woven and non-woven polypropylene bags come down to how they’re made. To create a durable fabric, plastic threads are tightly wound together in the more traditional manufacturing process for clothes that will last years without fail; on top of this material, there’s also an additional layer that makes them water-resistant or even leakproof if needed.

• 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 people’s awareness of environmental protection gradually strengthening, environmentally friendly products have become a new challenge faced by various enterprises. For packaging that is weight-for negotiates with the trend toward lightweight packages and uses less plastic than before; PP woven bags provide an excellent solution to this problem – they can be lighter yet still offer all these benefits!

At the same time, choosing reliable pp woven bags manufacturers in China is also important!
