(Abstract: Woven bags are a commonly used plastic bag. They are mainly made of polyethylene or polypropylene as raw materials, extruded and stretched into flat filaments, and then weaved, braided and made into bags. Due to the strength of polypropylene , rigidity and transparency are better than polyethylene, so they are used more. Woven bags are also widely used. They are generally used as packaging bags and can be used for packaging industrial and agricultural products, food, etc. In addition, tourism, engineering Woven bags are also used in the field of materials and flood fighting and disaster relief. Let's take a look at the materials and uses of woven bags.）

First,  What material is the woven bag made of?

    Woven bag, also known as snakeskin bag, is a kind of plastic bag, mainly used for packaging, so what is the material of plastic woven bag? Generally speaking, there are two types of raw materials for woven bags :

  1. Polyethylene

    Also known as PE plastic, it is a thermoplastic resin made by polymerizing ethylene. Polyethylene plastic woven bags have good performance, but polyethylene is sensitive to environmental stress and has poor heat aging resistance, so it is rarely used in China.

  2.Polypropylene

    Generally, most domestic woven bags are made of polypropylene as raw material. Polypropylene is a thermoplastic resin made by polymerizing propylene. It has three configurations: isotactic, atactic and syndiotactic. Its strength, Both rigidity and transparency are better than polyethylene, and the shortcomings of poor low temperature impact resistance and easy aging can be overcome by modification and addition of antioxidants.

Second, what is the use of plastic woven bags

    Woven bags have a wide range of uses. They are mainly used to package and package various items. They are most commonly used as packaging bags, and can also be used for engineering materials and flood-fighting materials. The main functions of woven bags are:

  1. Make packaging bags

     Industrial and agricultural products are commonly packaged in woven bags, including feed woven bags, chemical woven bags, putty powder woven bags, urea woven bags, vegetable mesh bags, fruit mesh bags, etc. In addition, food packaging such as rice and flour will also use woven bags.

 2. Tourism transportation industry

    Plastic woven bags are used in temporary tents, parasols, travel bags, travel bags, etc. in the tourism industry. They are widely used as covering materials for transportation and storage. Common ones include logistics bags, logistics packaging bags, freight bags, and freight packaging bags. wait.

  3. Make engineering materials

    Mainly used as a geotextile, it has the functions of filtration, drainage, reinforcement, isolation, and anti-seepage. It can be used in the construction of water conservancy, electric power, highways, seaports, and military buildings. Plastic woven bags are also used for flood control and disaster relief, such as flood control woven bags.,Drought-proof woven bags, flood-proof woven bags, etc.

    In general, woven bags have a wide range of uses, and although woven bags are made of plastic, they are highly environmentally friendly and recyclable, making them a very useful packaging bag.
