The types and application scope of woven bags

Many customers through our website to telephone to consult the kind of woven bag and application range, that today dongle woven bag xiaobian to explain the kind of woven bag and application range.

Knitted bags are also known as snakeskin bags. It’s a plastic, mainly used for packaging. Its raw materials are generally polyethylene, polypropylene and other chemical plastic raw materials. The following is an introduction to the types and applications of woven bags.


The main raw material for foreign production is polyethylene (PE), while the main material for domestic production is polypropylene (PP), a thermoplastic resin prepared by ethylene polymerization. Industrially, copolymers of ethylene with small amounts of -olefin are also included. Odorless, non-toxic, waxy polyethylene, with excellent low temperature resistance (minimum working temperature up to -70 ~ 100℃), good chemical stability, resistance to most acid and alkali corrosion (oxidation resistant acid), insoluble in general solvents at room temperature, low water absorption, excellent electrical insulation performance; It is polyethylene (chemical and electrical insulation) for environmental stresses; Mechanical effect) very sensitive, poor resistance to heat aging. The properties of polyethylene vary from species to species, mainly depending on its molecular structure and density. Products with different densities (0.91 to 0.96 g/cm3) can be obtained by different production methods. Polyethylene can be processed by a common thermoplastic forming process (see Plastic processing). Widely used in the manufacture of film, containers, pipelines, single wire, wire and cable, daily necessities, etc. It can also be used as high frequency insulation material for TV and radar. With the development of the petrochemical industry, polyethylene production has developed rapidly, accounting for about a quarter of the total plastic production. In 1983, the world total production capacity of polyethylene was 24.65 Mt, and the capacity of plant under construction was 3.16 Mt.


Thermoplastic resin prepared by propylene polymerization. There are three configurations of total isomorphism, random and interisomorphism. The main components of industrial products are homogenous substances. Polypropylene also includes copolymers of propylene and a small amount of ethylene. It is usually a translucent colorless solid, tasteless and non-toxic. Due to its regular structure and high crystallinity, the melting point is up to 167℃. It is heat resistant and the product can be sterilized by steam. A density of 0.90 g/cm3 is the lightest universal plastic. Corrosion resistance, tensile strength 30 MPa, strength, rigidity and transparency are better than polyethylene. The disadvantages are low impact resistance and easy aging at low temperature, which can be overcome by modification and addition of antioxidants respectively.

The color of woven bags is generally white or off-white, non-toxic and tasteless, generally less harmful to the human body. Although they are made from a variety of chemical plastics, they are environmentally friendly and recyclable.

Woven bags are widely used, mainly for packaging various items, and widely used in industry.

Plastic woven bag is made of polypropylene resin, extruded and stretched into flat silk, and then woven into bags.

Composite plastic woven bags are made of plastic fabric through a stream.

Used for packing powder or granular solid materials and flexible articles. The composite plastic woven bag is divided into two in-one bag and three in-one bag according to the main material composition.

According to the sewing method, it can be divided into sewing bottom bag, sewing edge bag, inserting bag and bonding sewing bag.

Depending on the effective width of the bag, it can be divided into 450, 500, 550, 600, 650 and 700 mm. Special specifications are agreed upon by the supplier and the consumer.

Range of application

1. Packaging bags for industrial and agricultural products

With the development and application of flexible container bags, plastic woven container bags are widely used in Marine, transportation and packaging industry and agricultural products. Plastic woven bags have been widely used in the packaging of agricultural products. Plastic woven bags have been widely used in aquatic products. Packaging, poultry feed packaging, farm covering materials, crop cultivation shading, windproof, hail shelter and other materials. Common products: feed woven bag, chemical woven bag, putty powder woven bag, urea woven bag, vegetable net bag, fruit net bag, etc.

2. Food packaging

Rice, flour and other food packaging gradually use woven bags. Common woven bags are: rice woven bags, flour woven bags, corn woven bags and other woven bags.

3. Tourism transport

Temporary tents, umbrellas, travel bags and bags in the tourism industry are used for plastic woven fabrics. Tents of various kinds are widely used as shelters

Temporary tents, umbrellas, travel bags and bags in the tourism industry are used for plastic woven fabrics. Tents are widely used as covering materials for transport and storage, replacing heavy and moldy cotton tents. Fences and mesh in buildings are also widely used in plastic fabrics. Common: logistics bags, logistics packaging bags. Freight packages, freight packages, etc.

Engineering materials

Since the development of geotextile in the 1980s, the application field of plastic woven fabric has been expanding, widely used in small water conservancy, electric power, highway, railway, port, mine construction and military construction. In these projects, geosynthetics have the functions of filtration, drainage, reinforcement, isolation and seepage control. Plastic geotextiles are one of synthetic geotextiles.

Flood control material

Woven bags are essential for flood control. They are also indispensable in the construction of embankments, rivers, railways and roads. They are anti – information woven bags, anti – drought woven bags and anti – flood woven bags.


Above is small make up for everybody finishing of woven bag type and the scope of application of related consulting, through the sharing of content, type and application range of the woven bags have certain cognitive, if you want to go deeper into the bag of market information, can contact the salesman in our company, or to the east and woven bag on-the-spot investigation, mutual communication is discussed in this paper.
