Sand And Stone Special Ton Bag

The container bag is polypropylene as the main raw material, adding a small amount of stability adjuvant evenly mixed, melt extrusion plastic film through the extruder, cut into silk, and then stretched, through heat shaping into high strength low elongation of PP raw silk, and then textile, film into plastic woven fabric base cloth, and other accessories stitched into tons of bags.

Design requirements of ton bag:
1, the base cloth is generally produced by flat loom or shuttle-round loom.
2, the ring, sling, knot is generally completed by the webbing machine.
3. The sewing thread can be made of nylon, polypropylene, poly vinegar and cotton.
4, the ton bag is required to have more than 5 times the safety factor, that is, its pressure resistance to accept five times the strength of the loading weight.
5, tons of bags need to moisture-proof function when necessary.
6, the sewing method of ton bag has three kinds of flat needle method, chain method and locking method.
Structural characteristics of ton bags
Ton bag full name flexible container bag, usually also known as space bag, ton bag. The bag body is made of flexible PP woven substrate. Suitable for packaging powder, flake, granular solid products, easy to transport and storage, compared with other packaging, ton bags generally do not need pallets, greatly saving the cost of packaging. After the film is coated, it is cut into cylindrical or sheet substrates of different sizes, and the ton bag is made of polyolefin resin by drawing and weaving process. Then, according to the design requirements, the base material is sewn into a round or square bag-like product. Ton bag is a kind of flexible transport packaging container, with plastic light, soft, acid and alkali corrosion resistance and moisture-proof, no leakage excellent performance; It has sufficient strength in structure, and has a firm and safe, convenient loading and unloading operation, and can be widely used in chemical industry, cement, grain, mineral products and other types of powder, granular, block items packaging.

Container bag manufacturers: How to distinguish the tons of bags produced by recycled materials?
Raw material production tons of bags used outdoors is about 8 months or more, generally speaking, the quality of tons of bags produced with recycled materials is poor, and the color of tons of bags produced with recycled materials is characterized by neither white nor transparent. The naked eye can only roughly identify it, want to be accurate still need to detect. If it can be detected, it is generally necessary to detect the appearance quality (whether there is broken wire, cleanliness, stitching quality, diameter and latitude density, length and width size, weight, etc.), tensile load (radial and latitude, seam edge and seam bottom), drop test, heat resistance, health performance, etc., we can use the hand to rub, if the surface crease is not obvious after flattening, the quality is better, and the feel is not crisp.
