Gravure-printed laminated packaging material production method and laminated packaging material produced by this method

摘要

An environment friendly method of producing gravure-printed laminated packaging materials is provided enabling a reduction in a quantity of organic solvents used in printing processes. The method includes gravure printing using aquatic gravure printing inks on a gravure-printed base film and laminating an intermediate base film and/or a heat-sealable film on the gravure-printed base film with an extrusion lamination method using a polarizing resin not requiring any anchor coating agent for the lamination. An extrusion lamination method using a polarizing resin not requiring any anchor coating agent may be used for the formation of a heat-sealable resin layer.
