What's the difference between PE plastic bag, PP plastic bag and PO plastic bag? Dongguan PE bag manufacturer

The difference between PE plastic bag, PP plastic bag and PO plastic bag;

PE

And PP are English abbreviations for raw materials. The chemical name of PE is linear polyethylene, which is divided into two types. One is high density linear polyethylene, which we usually call PO-HDPE, and the other is low density linear polyethylene, which we usually call PE-LDPE. In fact, there are two kinds of low-density linear polyethylene, LDPE and LLDPE (we will call them main materials and auxiliary materials respectively, but we should use them together when making plastic bags). The chemical name of PP is called polypropylene, and there is no more detailed distinction. There are three kinds of raw materials when signing the contract: LDPE/LLDPE/PP, and the finished products are PE plastic bags (PO plastic bags have no export names) and PP plastic bags.

The raw materials of bubble bag and bone bag are PE materials, that is, the synthetic materials of LDPE and LLDPE. The plastic bags used in general factories are also PE plastic bags, such as electronics factories, electrical appliances factories, hardware factories, plastic factories, clothing factories, shoe factories and so on.

PE plastic bags are widely used. The film used by farmers in spring ploughing is also made of PE, and the PE plastic bag looks transparent, feels smooth, has less soft sound and good toughness (this is LLDPE at work).

PP plastic bags are mostly used for gift packaging and finished clothing sales. All the new clothes we buy are packed in plastic bags, and the kind with a layer of double-sided tape is usually PO plastic bags.

PP plastic bags are very transparent and slippery to the touch, but they are hard, loud and brittle. There will be creases when folded in half, but there will be no creases when PE plastic bags are folded in half. Because of its good transparency, it looks high-grade when packaging gifts.

PP plastic bag is similar to PO plastic bag, but the transparency is not as good as PO plastic bag, so PP plastic bag has more advantages than PO plastic bag in price.
