Woven bags
Woven bags mainly to say: plastic woven bags are made of polypropylene as the main raw material, extruded, stretched into a flat wire, and then by weaving, compiling, bag making. Is a kind of plastic bags, used for packaging, its raw materials are generally polyethylene, polypropylene and other various chemical plastic raw materials. Weaving density refers to 100mm × 100mm woven fabric, the number of roots of the warp and weft yarns.
Product description
Woven bags are generally white or off-white in color, non-toxic and tasteless, generally less harmful to the human body, although it is made by a variety of chemical plastics, but its
environmental protection is stronger, and recycling efforts;
Woven bags have a wide range of uses, mainly used for a variety of items into the package and packaging, in the industrial aspect of a wide range of uses;
Plastic woven bags are made of polypropylene resin as the main raw material, by extrusion, stretching into flat wire, and then by weaving, bag making.
Composite plastic woven bags are made of plastic woven fabric as the base material, after the flow-delay method of composite.
Used for packaging powdery or granular solid materials and flexible items. Composite plastic woven bags according to the main material composition is divided into two-in-one bag and three-in-one bag.
According to the sewing method is divided into sewing bottom bag, sewing side bottom bag, insert bag, bonded sewing bag.
According to the effective width of the bag is divided into 450, 500, 550, 600, 650, 700mm, special specifications agreed by the supply and demand sides.

Scope of Application
Packing Bags
1. Industrial and agricultural products packaging bags
Due to product resources and price problems, China has 6 billion woven bags for cement packaging each year, accounting for more than 85% of the bulk cement packaging. With the development and application of flexible container bags, plastic woven container bags are widely used in the sea, transportation packaging of industrial and agricultural products, packaging of agricultural products, plastic woven bags have been widely used in aquatic products packaging, poultry feed packaging, farms, covering materials, crop cultivation of sunshade, windbreaks, hail-proof shed and other materials. Common products: feed woven bag, chemical woven bag, putty powder woven bag, urea woven bag, vegetable mesh bag, fruit mesh bag and so on.
2.Food Packaging Bags
Rice, flour and other food packaging gradually adopted woven bags. Common woven bags are: rice woven bags, flour woven bags, corn woven bags and other woven bags.
3. Tourism and transportation
Temporary tents in the tourism industry, umbrellas, a variety of travel bags, travel bags, have plastic woven applications, a variety of tarpaulins are widely used for transportation and storage of covering materials, instead of easy to mold and heavy cotton tarpaulin. Construction of fences, nets, etc. are also widely used in plastic woven fabrics. Commonly used: logistics bags, logistics packaging bags, freight bags, freight packaging bags, etc.
Engineering Materials
Since the development of geotextiles in the 80's, the application of plastic woven fabrics has been broadened, and they are widely used in small water conservancy, electric power, highways, railroads, seaports, mine construction, military engineering construction. In these projects, geosynthetics have the function of filtration, drainage, reinforcement, isolation, seepage control, etc. Plastic geotextile is one kind of synthetic geomaterials.
Flood relief materials
Woven bags are indispensable for flood relief. Woven bags are also used in the construction of dams, riverbanks, railroads and highways. It is flood control woven bag, drought-proof woven bag, flood control woven bag.
