Abstract
The present invention relates to a laminated member comprising a polyethylene resin composition layer having a very high adhesive strength to a substrate, and a method for manufacturing the same. The present invention is directed to a method for manufacturing the laminated member, which has a high adhesive strength to a different kind of substrate within a range from low to high temperature, and can reduce the resin temperature during the extrusion-lamination molding and inhibit any noxious influence on the working and surrounding environments, and is also superior in terms of high-speed mold ability at low temperature, and the laminated member. In the present invention, a compound having a specific structure is incorporated into a polyethylene resin composition layer. The present invention can be used to particular advantage in laminate products such as packaging material.
