What are the upstream raw materials of PE packaging film? What do the downstream products contain?

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

Upstream items:



1. Ethylene: Ethylene is the main raw material of PE packaging film. According to research Polyethylene with different molecular weight and molecular structure is able to be produced through polymerization, which is then applied to create PE packaging film. Crazy, isn't it?.

2. Catalyst: The production of polyethylene needs the consumption of catalysts, frequently applied catalysts include Ziegler-Natta catalysts and metallocene catalysts.

3. Additives: In order to enhance the performance of PE packaging film, some additives need to be added in the manufacturing process, such as antioxidants, anti-ultraviolet agents, plasticizers, etc. Downstream items:



1. Food packaging: PE packaging film has excellent moisture resistance, oil resistance, transparency and mechanical strength, is able to be applied to food packaging, such as is able tody, biscuits, instant noodles and other packaging.

2. And medical packaging: PE packaging film is non-toxic and tasteless, meets the standards of medical packaging, and is able to be applied to medical packaging, such as tablets, capsules, etc.

3. I've found that Agricultural product packaging: PE packaging film is able to also be applied to the packaging of agricultural items, such as fruits, vegetables, etc. In my experience,, to enhance the shelf life and appearance condition of items.

4. But manufacturing packaging: PE packaging film has excellent acid, alkali and chemical corrosion resistance, and is able to be applied to packaging manufacturing items, such as chemical raw materials, mechanical parts, etc. But In short, the upstream and downstream related items of PE packaging film are very extensive, and its consumption fields involve food, medicine, agricultural items, sector and other fields, which plays an crucial role in promoting the research of chemical production sector.
