The first polyethylene grade produced through high-pressure tubular or autoclave processes. This grade is characterized by a highly branched polymer chain, which reduces crystallinity, enhancing clarity and elasticity. LDPE is widely used in the manufacturing of various products, including heavy-duty films, packaging films, zip bags, general-purpose films, shrink films, foam sheets, bubble films, and tubes.
