Both are plastic, but the material is different, PE is polyethylene, OPP is polypropylene.

OPP film is oriented tensile polypropylene film. It is the polymer polypropylene melt that is first made into sheet or thick film, at a certain temperature and set speed, in the vertical two directions of stretching, and through special processing made of film.

PE film is a thermoplastic resin film prepared by ethylene polymerization. Polyethylene film is odorless, non-toxic, feels like wax, has excellent low-temperature resistance, good chemical stability, resistance to most acid and alkali erosion, low water absorption, and good electrical insulation performance.

What are the differences between pe bags, po bags and opp bags?

1. The difference between pe bag and po bag is as follows:

PE packaging bags are made of LDPE and LLDPE raw materials made by addition polymerization of low-density ethylene, which are melted and blow-molded after batching. The bag has 90% transparency, is soft, has a low melting point, has good toughness, is non-toxic, and is not easy to tear. Products are often used in industrial packaging such as clothing, electronics, toys, etc.

PO bag is made of HDPE and low-density polyethylene LLDPE made by addition polymerization of high-density ethylene, melted and blow-molded after batching. The bag has 60% transparency, is hard, has a high melting point, is non-toxic, and is easy to be brittle. Products are often used in shopping bags, handbags, shopping mall bags, and industrial packaging bags.

The common point of PE and PO plastic bags is that they are raw materials made of ethylene addition polymerization. The difference is that their density is different, and the products produced are also used for different purposes.

The difference between PE bag and OPP bag

PE bag and OPP bag are two common plastic bags in the market. Although the use of both can bring more benefits to people, there are also differences between the two. So, what is the difference between PE packaging bag and OPP bag? The following is a brief introduction to this problem.

Appearance

There is a clear difference in appearance between PE bags and OPP bags. Under normal circumstances, the former is translucent and has a good feel, while the latter is transparent and has good toughness, and it feels smooth to the touch. The two can be distinguished well by the appearance.

Purpose

There is also a difference in the use of PE bags and OPP bags. Under normal circumstances, PE bags are used to hold ordinary products, such as electrical appliances, toys, or tools. This phenomenon occurs because such products have relatively high toughness, reducing the probability of damage. OPP bags can be used as packaging for clothing products due to their good transparency.

Through the above introduction, people should know the difference between PE bags and OPP bags. In order to better meet the needs of use, they should choose the appropriate packaging bags according to the actual choices, so as to avoid unnecessary economic losses. I also hope that the above introduction can help people.
