Low-Density Polyethylene (LDPE) is a semi-crystalline, non-polar thermoplastic resin produced through the high-pressure polymerization of ethylene monomers. Unlike HDPE, LDPE features a highly branched molecular structure, resulting in lower crystallinity (40-50%) and density (0.910-0.940 g/cm³). This unique structure provides exceptional flexibility, transparency, and processability, making it ideal for films, coatings, and soft packaging.
