What are the materials of rice bags?

　　We will use all kinds of plastic bags in our life, so what is the material of rice bag? There are many materials used in rice bags, the most commonly used and the most commonly used in daily life are. PE, PO, PP, OPP, EVA, PVC, CPE, PPE.

　　More complex composite bags, on the other hand, use a wider range of materials.

　　Include: KOP(coated with bidirectional tensile polypropylene), MATOPP(coated with bidirectional tensile polypropylene matte film), PCO(double-sided or single-sided heat-sealed biaxial oriented polypropylene), PL(bidirectional tensile polypropylene pearlite film), polyethylene terephthalate Film, KPET(coated with polyethylene terephthalate film), Nylon (NY), Aluminum (aluminum foil), PE(polyethylene), CPP(non-stretched polypropylene), VMCPP(aluminized unstretched polypropylene), VMPET(aluminized polyester film), there are more than ten kinds of materials.

　　In this article, we will first detail some characteristics of commonly used rice bags. What is the rice bag made of?

　　Commonly used rice bag material characteristics, PE(polyethylene), PE(polyethylene) is a thermoplastic resin from ethylene polymerization.

　　Industrially, it also includes ethylene and less ethylene, a copolymer of α-olefin content. Polyethylene is odorless, non-toxic, feels like wax, and has excellent resistance to low temperatures.

　　In the field of packaging bags, PE materials are divided into low density high pressure polyethylene (LDPE) and high density low pressure polyethylene (HDPE) two categories. LDPE bags are soft, smooth, transparent and versatile.

　　They are usually suitable for clothing bags, such as plastic bags and plastic, rice bags and other commonly used bags in the clothing field.

　　Usually we turn LDPE bags into PE bags.

　　High density polyethylene (PO), which is actually still PE material, is a more colloquial name for HDPE. Bags made of PO material are hard and brittle and make a lot of noise when rubbed. Bags that use PO materials more are takeout or hotel bags, vest bags used in shopping malls and supermarkets. Of course, there are many clothing brands and tobacco and alcohol brands that use PO plastic bags made from PO materials.

　　First of all, the price is cheaper than the paper bag, secondly, the texture is not much lower than the paper bag.

　　PO packing box: PP bag is made of stretched polypropylene plastic, it is characterized by non-toxic, tasteless, smooth and transparent surface, PP is a transparent material, often used in the production of flat pockets and adhesive bags, mainly used in electronics, hardware and clothing fields. The bag made of PP material has high transparency, so that consumers can clearly see the goods packaged in the bag, and the cost is low. It is a lightweight commodity. Packing is the first choice. Oriented polypropylene (OPP). OPP is a kind of oriented tensile polypropylene material with high transparency and brittleness. The back edge of the OPP is folded in half and a self-adhesive seal is attached to the open tongue. When used, use this product to remove the protective skin on the surface of the seal, and then remove the tongue.
