PE packaging film has a wide range of applications in the field of chemical production raw materials, and its upstream and downstream related products are numerous. The following are some of the main upstream and downstream related products:

upstream products:

1. ethylene: ethylene is the main raw material of PE packaging film, through polymerization reaction can produce different molecular weight and molecular structure of polyethylene, and then used in the production of PE packaging film.
2. Catalyst: The production of polyethylene requires the use of catalysts, and commonly used catalysts include Ziegler-Natta catalysts and metallocene catalysts.
3. Additives: In order to improve the performance of PE packaging film, some additives need to be added in the production process, such as antioxidants, anti-ultraviolet agents, plasticizers, etc.

downstream products:

1. Food packaging: PE packaging film has excellent moisture resistance, oil resistance, transparency and mechanical strength, and can be used for food packaging, such as candy, biscuits, instant noodles and other packaging.
2. Pharmaceutical packaging: PE packaging film is non-toxic and tasteless, meets the requirements of pharmaceutical packaging, and can be used for pharmaceutical packaging, such as tablets, capsules, etc.
3. Agricultural products packaging: PE packaging film can also be used for the packaging of agricultural products, such as fruits, vegetables, etc., to improve the shelf life and appearance quality of products.
4. Industrial packaging: PE packaging film has excellent acid, alkali and chemical corrosion resistance, and can be used for packaging industrial products, such as chemical raw materials, mechanical parts, etc.

In short, the upstream and downstream related products of PE packaging film are very extensive, and its application fields involve food, medicine, agricultural products, industry and other fields, which plays an important role in promoting the development of chemical production industry.
