Abstract
The shape-forming packaging material is a shape-forming packaging material including a heat resistant resin layer as an outer layer, a heat fusible resin layer as an inner layer, and a metal foil layer disposed between both the layers, and is configured such that a print improving resin layer is laminated on a further outer side of the heat resistant resin layer.
Claims13
A shape-forming packaging material comprising:
- a heat resistant resin layer as an outer layer;
- a heat fusible resin layer as an inner layer;
- and
- a metal foil layer disposed between the heat resistant resin layer and the heat fusible resin layer,
- wherein a print improving resin layer is laminated on an outer side of the heat resistant resin layer opposite the metal foil layer, the print improving resin layer includes a formation amount of between 0.01 g/m2 and 0.5 g/m2,
- wherein a lubricant is exuded to an outer surface of the heat fusible resin layer, the lubricant then is adhered without lamination to an outer surface of the print improving resin layer wherein an adhesion amount of the lubricant on the outer surface of the print improving resin layer is 0.1 mg/m2 to 2.5 mg/m2 and wherein the adhesion amount of lubricant on the outer surface of the printing improving resin layer is smaller than the adhesion amount of the lubricant on the outer surface of the heat-fusible resin layer, and
- wherein the print improving resin layer is a single layer that is an outermost layer of the packaging material.
