,又称蛇皮袋。 Woven bag , also known as snake skin bag . It is a type of plastic bag used for packaging. Its raw materials are generally various chemical plastic materials such as polyethylene and polypropylene. Knitting density refers to the number of warp and weft yarns in a 100mm × 100mm knitted fabric.

Definition of plastic woven bags : Woven bags are mainly: plastic woven bags are made of polypropylene (English name pp) as the main raw material, extruded and stretched into flat yarns, and then woven, knitted, and bagged.

Common parameters of woven bag:

Common woven cloth density is 36 × 36 pieces / 10cm & sup2 ;, 40 × 40 pieces / 10cm & sup2 ;, 48 × 48 pieces / 10cm & sup2 ;.

1. Braid density tolerance.

Knitting density tolerance refers to more than the given standard knitting density or reducing the number of flat yarns.

2. Mass per unit area of woven cloth.

The unit area weight of the woven cloth is expressed by the weight of square meters, which is an important technical index of the woven cloth. The weight in square meters mainly depends on the density of warp and weft and the thickness of the flat yarn. The weight in square meters affects the tensile strength and load capacity of the woven fabric. The weight in square meters is a major link for manufacturing companies to control costs.

3. Woven cloth tensile load.

Tensile load is also called tensile strength, tensile strength. As for the woven cloth, it bears the tensile load in the warp and weft directions, so it is called the warp and weft tensile load.

4. Width.

The width of various woven fabrics directly affects the bag making process. For tube cloth, the width is indicated by the folded warp, which is equal to half the circumference.

The width shrinkage rate, the width of all woven fabrics after weaving and rolling, after the roll cutting, printing, and stitching, the width of the bag made is slightly smaller than the width at the time of winding. We call the width shrinking.

5. Feel.

PP flat silk knitted fabric feels thick, quite wide and thick.

HDPE flat silk braid is soft, smooth and not dense.

Adding calcium masterbatch to PP flat silk material has a wide feel, and adding less HDPE to PP will make it softer.

Flat silk is narrow, flat weaving, soft to the touch, wide flat silk, there are many folded silks when weaving cloth, and the texture is rough.

Type of woven bag:

The main raw material for foreign production is polyethylene (PE), and the main domestic production is polypropylene (PP), which is a thermoplastic resin produced by the polymerization of ethylene. Industrially, it also includes copolymers of ethylene and small amounts of α-olefins. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance (minimum use temperature can reach -70 ~ -100 ℃), good chemical stability, can withstand most acid and alkali erosion (not resistant to oxidizing properties) Acid), insoluble in general solvents at room temperature, low water absorption, and excellent electrical insulation properties; but polyethylene is very sensitive to environmental stress (chemical and mechanical effects), and has poor heat aging resistance. The properties of polyethylene vary from species to species, mainly depending on the molecular structure and density. Different production methods can be used to obtain products with different densities (0.91 to 0.96 g / cm3). Polyethylene can be processed by common thermoplastic molding methods (see Plastic Processing). It has a wide range of uses, mainly used to manufacture films, containers, pipes, monofilaments, wires and cables, daily necessities, etc., and can be used as high-frequency insulation materials such as televisions and radars. With the development of petrochemical industry, polyethylene production has developed rapidly, and the output accounts for about 1/4 of the total plastic output. In 1983, the total polyethylene production capacity in the world was 24.65Mt, and the capacity of devices under construction was 3.16Mt.

Polypropylene (PP)

A thermoplastic resin made by the polymerization of propylene. There are three configurations of isotactic, irregular and syndiotactic substances. Industrial products are based on isotactic substances. Polypropylene also includes copolymers of propylene and a small amount of ethylene. Usually a translucent colorless solid, odorless and non-toxic. Because the structure is regular and highly crystallized, the melting point is as high as 167 ° C, heat resistance, and the product can be sterilized by steam is its outstanding advantage. The density is 0.90g / cm3, which is the lightest general-purpose plastic. Corrosion resistance, tensile strength 30MPa, strength, rigidity and transparency are better than polyethylene. Disadvantages are poor low temperature impact resistance and easier ageing, but they can be overcome by modifying and adding antioxidants, respectively.

The color of the woven bag is generally white or off-white, non-toxic and tasteless, and generally less harmful to the human body. Although it is made of various chemical plastics, it is more environmentally friendly and has a stronger recycling strength;

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

The plastic woven bag is made of polypropylene resin as the main raw material, extruded and stretched into flat yarn, and then woven and bag-made.

The composite plastic woven bag is made of plastic woven cloth as a base material and is compounded by a casting method.

For packaging powdery or granular solid materials and flexible items. Composite plastic woven bags are divided into two-in-one bags and three-in-one bags according to the main material composition.

According to the sewing method, it can be divided into bottom-stitched bags, bottom-stitched bottom bags, insert pockets and adhesive sewing bags.

According to the effective width of the bag, it is divided into 450, 500, 550, 600, 650, 700mm, and special specifications are negotiated between the supply and demand sides.

Applications of woven bags:

1. Industrial and agricultural product packaging bags

Due to product resource and price issues, China has 6 billion woven bags for cement packaging each year, accounting for more than 85% of bulk cement packaging. With the development and application of flexible container bags, plastic woven container bags are widely used at sea. Transport packaging industry for agricultural products. In agricultural product packaging, plastic woven bags have been widely used in aquatic product packaging, poultry feed packaging, covering materials for farms, shades for crop cultivation, windproof, hailproof sheds and other materials. Common products: feed Woven bags, chemical woven bags , putty powder woven bags, urea woven bags, vegetable mesh bags, fruit mesh bags, etc.

2. Food packaging bag

Rice, flour and other food packaging are gradually packed in 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, parasols, various travel bags, and travel bags in the tourism industry have plastic woven fabric applications.A variety of tarpaulins are widely used as covering materials for transportation and storage, replacing cotton tarpaulins that are prone to mildew. Fences, nets, etc. in construction are also widely used in plastic woven fabrics. Common ones are: logistics bags, logistics packaging bags, freight bags, freight packaging bags, etc.

Engineering Materials

Since the development of geotextiles in the 1980s, the application fields of plastic braids have been broadened, and they are widely used in small water conservancy, electricity, highways, railways, seaports, mining constructions, and military engineering constructions. In these projects, geosynthetics have filtering , Drainage, strengthening, isolation, anti-seepage and other functions, plastic geotextile is a kind of synthetic geotechnical materials.

Anti-flood materials

Woven bags are needed for flood relief. Weaving bags are also needed in the construction of dams, river banks, railways, and highways. They are anti-communication woven bags, drought-proof woven bags, and flood-proof woven bags.
