HIGHLY ADHESIVE RESIN COMPOSITION FOR EXTRUSION COATING

摘要

PURPOSE: A highly adhesive resin composition for extrusion coating is provided, to improve the adhesive power, thereby allowing extrusion coating or extrusion laminating to be carried out without an anchor coating agent. CONSTITUTION: The resin composition for extrusion coating comprises 80-98 wt% of a low density polyethylene resin, a linear low density polyethylene resin or an ethylene vinyl acetate; 2-20 wt% of an ethylene-α-olefin copolymer with a melting index of 0.5-30 g/10 min and a density of 0.80-0.90 g/cm¬3. Preferably the low density polyethylene resin has a melting index of 1-15 g/10 min and a density of 0.915-0.928 g/cm¬3; the linear low density polyethylene resin has a melting index of 5-30 g/10 min and a density of 0.928-0.940 g/cm¬3; and the ethylene vinyl acetate has a melting index of 5-40 g/10 min and contains 3-50 wt% of vinyl acetate.
