bulk bags material characteristics

bulk bags is a plastic tube cloth, packaging, the raw material is polyethylene, polypropylene, and other chemical raw materials, bulk bags are polypropylene resin as the main raw material, extruded, stretched into flat yarn, and then by weaving, a bag made. Here we introduce the bulk bags tube cloth material characteristics.
bulk bags

bulk bags cartridge production is mainly polypropylene. Polypropylene is a thermoplastic resin obtained by polymerization of propylene.

Polypropylene raw material

Mainly used for all kinds of long and short polypropylene fiber production, used in the production of polypropylene bulk bags, packing bags, injection molding products for the production of electrical appliances, telecommunications, lighting, lighting equipment, and TV flame retardant parts.

Polypropylene bulk bags

Polypropylene has a lot of properties.:

1, Strong elongation

Polypropylene high strength, elongation, high initial modulus, excellent elasticity. Therefore, polypropylene wears resistance. In addition, the wet strength of polypropylene is basically equal to dry strength, so it is the ideal material for the production of fishing nets, cables.

2, hygroscopicity and staining

Light and warm good, almost no moisture absorption, but the wicking ability are very strong, the wicking effect is obvious; polypropylene hygroscopicity is very small, the moisture regains in general atmospheric conditions close to zero. But it has a wicking effect, through the capillary transfer of water vapor in the fabric, but itself can not afford any absorption. Polypropylene staining is poor, incomplete chromatography, but can be used to compensate for the lack of liquid coloring method.
