Abstract
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.
Claims8
An environment friendly method of producing gravure-printed laminated packaging materials enabling reduction in a quantity of organic solvents used in printing processes, the method comprising:
- 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.
A method of producing a gravure-printed laminated packaging materials each comprising a gravure-printed base film, an intermediate layer base film laminated on the base film, and a heat-sealable resin layer formed on a surface of the base film or the intermediate layer base film, the method comprising:
- employing a gravure printing method using aquatic gravure printing inks for the gravure printing process and employing an extrusion lamination method using a polarizing resin not requiring any anchor coating agent for the lamination process, and employing an extrusion lamination method using a polarizing resin not requiring application of an anchor coating agent for formation of the heat-sealable resin layer.
A gravure-printed laminated packaging material comprising:
- a base film gravure-printed with aquatic gravure printing inks;
- and a polarizing resin layer formed by an extrusion lamination method as a resin layer for lamination between the base film and the intermediate layer base film and/or heat-sealable film laminated thereon.
A gravure-printed laminated packaging material comprising:
- a gravure-printed base film;
- an intermediate layer basic film laminated on the basic film;
- and a heat-sealable resin layer formed on a surface of the base film or the intermediate layer base film, wherein a gravure-printing method using aquatic gravure printing inks are used for the gravure printing process for forming the gravure-printed base film and a polarizing resin not requiring application of an anchor coating agent is used with the extrusion lamination method as the resin for lamination in the lamination process, and further a polarizing resin not requiring application of an anchor coating agent and formed by the extrusion lamination method is used for formation of the heat-sealable resin layer.
