Because the market for woven bags is very large, the price difference of woven bags is also very large. The price factors that determine woven bags are mainly materials and production methods. Therefore, when you want to buy a good woven bag, there are many factors to consider.
Woven bag, also known as snake skin bag. It is a kind of plastic bag, used for packaging, and its raw materials are generally polyethylene, polypropylene and other chemical plastic raw materials. Weaving density refers to the number of warp and weft yarn in 100mm×100mm woven fabric. When purchasing woven bags, we first look at what products are packaged in the woven bags required, because the material requirements of the woven bags required are different for different products.
When buying woven bags, we should consider these factors:
1. Braid density tolerance.
Braid density tolerance refers to more than a given standard braid density or a reduction in the number of strands of flat wire.
2. Quality of woven fabric per unit area.
The weight per unit area of braided cloth is expressed in grams of square meters, which is an important technical index of braided cloth. The gram weight of square meter mainly depends on the warp and weft density and the thickness of the flat wire. The gram weight of square meter affects the tensile strength and load capacity of the woven cloth. The gram weight of square meter is a main link in the cost control of the production enterprise.
3. Woven fabric tensile load.
Tensile load is also called tensile strength, tensile strength. For braided booker to bear the tensile load in two directions of warp and weft, it is called warp and weft tensile load.
4. Width.
Various woven widths directly affect the bag-making process. For tube cloth, the width is expressed by bending, and the bending is equal to half the circumference.
Width retraction rate, the width of all woven fabrics after weaving and rolling, after rolling cutting, printing, stitching, the width of the made bag should be slightly less than the width when rolling, we call width retraction.
5. Feel.
PP flat woven fabric feel thicker, quite wide, rough and hard.
HDPE flat woven fabrics feel soft, lubricated, not dense.
Add calcium masterbatch to PP flat wire material, feel quite wide, PP less HDPE will make it softer.
Flat wire is narrow, woven flat, soft feel, flat wire is wide, folding silk when weaving cloth, feel rough.
