What Is Low-Density Polyethylene?
Low-density polyethylene (LDPE) is a plastic made by polymerizing ethylene. It is characterized by its flexibility, resistance to low temperatures, chemical resilience, transparency, and ease of processing.
The production of LDPE starts with the polymerization of ethylene, which creates long carbon chains of high molecular weight. This process is carefully controlled and stopped at a specific point, allowing the resulting resin to be cooled and solidified. The solid resin is then broken down into pellets, which are later melted and formed into a wide range of products.
LDPE is widely used in manufacturing packaging materials, agricultural products, industrial goods, and household items. Its key properties include being lightweight, flexible, transparent, cold-resistant, chemically resistant, easy to process, and capable of being produced on a large scale.
