How are big bags tested?
The tolerance of the weaving density of the big bag refers to the number of flat wires that are more or less than the given standard weaving density. The weight per unit area of the ton bag is represented by the number of grams per square meter, which is an important technical indicator of woven fabrics. The weight per square meter mainly depends on the warp and weft density and the thickness of the flat yarn. The number of grams per square meter affects the weaving The tensile strength, load capacity, and grammage of the cloth are a major part of the production enterprise's cost control.
The tensile load of the container bag is also called the tensile strength and the tensile strength. For the woven fabric, it bears the tensile load in both the warp and weft directions, so it is called the warp and weft tensile load.
According to professionals who specialize in ton bags, the width of various woven fabrics directly affects the bag-making process. For tube cloth, the width is represented by the folded warp, which is equal to half of the circumference. Width shrinkage, the width of all woven fabrics after weaving and winding, after unwinding, cutting, printing, and sewing, the width of the bag made is slightly smaller than the width of the winding, we call it width shrinkage.
Introduction PP flat wire braids feel thicker, wider, and thicker; HDPE flat wire braids feel softer, lubricated, and not dense. Calcium masterbatch is added to PP flat wire material, and the hand feeling is quite wide. Adding less HDPE to PP will make it softer; the flat wire is narrow, the weaving is flat, the hand feels soft, the flat wire is wide, and the folded wire is more assembled when weaving the cloth. Tongling container bag production knowledge feels rough.
Load capacity of big bags
The material of the container bag manufacturer is rainproof and impermeable, and it can also prevent moisture when it is placed outdoors after being filled. Easy to transport. There is a special lifting ring on the container bag, which is convenient for lifting equipment, loading and unloading.
Long life, can be used many times. Big bags are made of high-strength materials, durable and recyclable. Can greatly improve loading and unloading efficiency. It has large capacity, fast loading and unloading, and improves work efficiency by more than ten times compared with conventional paper bag packaging.
The valve pocket takes up less space. The empty bag is foldable, small in size, and the full bag has a large capacity, which saves space compared to small bags. According to professionals who specialize in the production of ton bags, container bags have a wide range of packaging. As long as it is powder and granular products, container bags can be packed almost.
Container bags can be widely used in the packaging of various powdery, granular and lumpy items such as chemical, cement, grain, mineral products, etc. It is an ideal product for storage, transportation and other industries.
