Low-Density Polyethylene (LDPE)

Brief Introduction:
Low-Density Polyethylene (LDPE) is a type of polyethylene produced through low-pressure polymerization of ethylene. This material is widely used in packaging and the production of plastic films due to its flexibility, softness, and chemical resistance. LDPE is especially utilized in the production of shopping bags, protective covers, and plastic containers.

Product Category:
Low-Density Polyethylene falls under polymers and packaging materials.

Applications:

1. Packaging Films:
   Used in the production of thin, flexible films for packaging food and other goods.
2. Shopping Bags:
   Utilized in the production of plastic shopping bags and trash bags.
3. Plastic Containers:
   Employed in producing disposable containers and food packaging.
4. Covers:
   Acts as a cover for various products in agriculture and construction.

Scientific Properties:

• Density: Ranges from 0.91 to 0.94 g/cm³.
