High-performance Low Density Polyethylene (LDPE) for extrusion coating with a superior balance of processability and adhesion


[cite_start]

COSMOTHENE® L420 is a specialized Low Density Polyethylene (LDPE) resin engineered primarily for extrusion coating applications[cite: 1138, 1140, 1180]. [cite_start]It is characterized by an excellent balance between neck-in performance and overall processability, ensuring efficient production across various substrates[cite: 1143]. [cite_start]L420 is specifically designed to provide strong heat seal properties and high adhesion to base films, making it a reliable choice for complex laminates[cite: 1143]. [cite_start]Formulated without additives, this grade complies with U.S. FDA Regulation 21 CFR 177.1520 (C) 2.1 for food contact, provided it is processed according to standard industry practices[cite: 1144, 1147].
