Low-Density Polyethylene (LDPE) is a soft, tough, transparent thermoplastic material. LDPE is stable to most acids, alkalis, and salts, commonly used in the processing of packaging film, soft containers, etc; however, due to the soft texture, it is easy to be deformed in CNC processing, and is usually used only for CNC processing of simple structures or thick-walled functional parts.
