[Detailed description of the invention] <Industrial application field> The present invention relates to a heat-sealing lid material that includes a base material with a printed layer on the back side, and this heat-sealing lid material,
The present invention relates to a heat-sealing lid material that is free from the risk of peeling off from a printed layer even if the seal is opened after heat-sealing.

<Prior Art> Conventionally, heat-sealing lid materials have been heat-sealing materials in which a hot-melt adhesive layer is provided on a base material, or heat-sealing materials in which a polyethylene layer is provided between the base material and the hot-melt adhesive layer.

However, among these materials, it is common to have a printed layer on the back side of the base material. In some cases, the entire heat-sealing lid material did not peel off, but the printed layer peeled off, making it impossible to open the lid.

In order to prevent the printed layer from peeling off, the printed layer may not be provided only in the heat-sealed area, but this may limit the area where the printed layer is provided, resulting in a smaller pattern or placing restrictions on the printed pattern. I had already received it.

Further, even if the printed layer is provided with sufficient care, there is a risk that the printed layer may be misaligned during sealing, causing the printed layer to harden in the heat-sealed area.

<Problems to be solved by the invention> The invention solves the disadvantages of partially providing a printing layer by providing a printing layer on the entire lid material instead of providing a printing layer partially. Moreover, it is an object of the present invention to provide a heat-sealing lid material that is free from the risk of peeling off at the printed layer even if the lid is opened after heat-sealing.

<Means for Solving the Problems> The present invention is based on a plastic film alone or a base material made of plastic film and aluminum foil and having a printing layer on the entire back surface, and a biaxial stretched polypropylene film,
This is a heat-sealing lid material that includes an intervening layer made of a type of nylon film or polyester film, a polyethylene layer, and a hot melt layer.

<Function> The present invention has a structure in which an intervening layer made of one of biaxially oriented polypropylene film, nylon film, and polyester film is provided on the printing layer side of the base material with a printing layer on the back side. Even if the lid material is unsealed after the material is heat-sealed, the entire lid material can be unsealed because the adhesive strength between the base material and the intervening layer is greater than the heat sealing strength of the hot melt layer.

Furthermore, since the printed layer does not peel off when the package is opened, the printed layer can be provided on the entire back surface.

Furthermore, since the polyethylene layer and/or hot melt layer of the conventional structure is provided by extrusion coating, the material often curls toward the base material. However, since the material of the present invention is manufactured by laminating the base material and the intervening layer, the tension can be adjusted at the lamination stage and then extruded and laminated, resulting in a curl-free material.
