Abstract
A sealant resin composition for retort packaging film comprises a high density polyethylene as the main resin component and a linear low density polyethylene polymerized by use of the metallocene catalyst. A sealant film produced therefrom is resistant to whitening, heat fusion, heat deformation after being subjected to boiling sterilization treatment and prevent breakage of pouches produced therefrom even at low temperatures because of its high impact strength and heat sealing strength.
