LDPE (Low-Density Polyethylene) is a thermoplastic polymer belonging to the polyethylene family. LDPE is produced from ethylene monomers and is called “low-density polyethylene” because it has a low density. LDPE has several advantages and has a wide range of applications. LDPE is a type of polyethylene with a low density. This makes the material lightweight. LDPE has high flexibility and elasticity properties. This makes the material suitable for many different applications, especially in flexible packaging materials. LDPE is resistant to many chemicals. This feature increases its usability in various industrial and packaging applications.
