In this case, the packaging film 10 preferably has a notch 12 at the sealed end 11, and a direction perpendicular to the direction in which the end 11 extends (X in the figure, starting from the notch 12). Tearable along the direction).

  FIG. 4 is a schematic front view of a packaging material 101 according to another embodiment of the present invention, and FIG. 5 is a schematic rear view of the packaging material 101. The packaging material 101 has an opening tape 50 disposed inside the packaging film 10. The packaging film 10 is configured to be tearable along the longitudinal direction of the tear tape 50 by pulling the end of the tear tape 50. In the packaging material 101 of the illustrated example, the packaging film 10 packages the package by being folded so as to wrap the package. The packaging material 101 is typically a packaging material for packaging a substantially triangular rice ball. In the packaging film 10 of the illustrated example, the opening tape 50 is disposed so that the front surface is longitudinally cut from the upper end to the lower end, straddles the bottom, and the rear surface is longitudinally cut from the lower end to the upper end. The packaging film 10 can be cut at the front end from the upper end to the lower end by pulling the end of the tear-off tape 50 and can be cut at the rear end from the lower end to the upper end. In one embodiment, the packaging material 101 has a label 20 on the front and a label 20A on the back. The label 20 has a recess 30 at the edge that intersects with the tear of the packaging film 10 when the packaging film 10 is torn, and the label 20A also has a recess 30A. That is, typically, the label 20 has the recess 30 at the edge of the upper end, and the label 20A has the recess 30A at the edge of the lower end. Furthermore, as described with reference to FIGS. 1 and 2, the labels 20, 20A have notches 31, 31A extending in the recess direction of the packaging film 10 in the recesses 30, 30A. Thus, the packaging material 101 can be easily torn together with the packaging film 10 and the labels 20 and 20A by pulling the end of the tear-off tape 50, and can be easily opened. In the example shown in FIGS. 4 and 5, the concave portions 30, 30A are V-shaped, but may be U-shaped as shown in FIG.

B. Packaging film As described above, the packaging film is configured to package the package and to be ripped in a predetermined direction. The packaging aspect by a packaging film is not specifically limited, It is not limited to airtight packaging. As a to-be-packaged thing, foodstuffs, such as a rice ball and a confectionery, are mentioned, for example.

  In one embodiment, as shown in FIG. 1, the packaging film is formed in a bag shape. In this case, the type of the bag formed by the packaging film is not particularly limited, and examples thereof include a combination bag, a gusset bag, and a three-way bag. In this case, the packaging film is typically heat-sealed with the end portions overlapped, and preferably has a notch in the seal portion. The notched portion may be in the form of a serrated or corrugated shape formed at the end, or may be a notch such as a V-shaped or I-shaped. Thereby, the packaging film formed in a bag shape can be torn along the direction (X direction in the figure) orthogonal to the direction in which the end portion extends from the notch.

  In another embodiment, as shown in FIGS. 4 and 5, the packaging film is folded so as to wrap the package. In this case, typically, the end of the packaging film is attached with a label so that the packaging film is fixed so as not to open. In the packaging material of the present embodiment, the packaging film can be torn along the longitudinal direction of the tear tape (the direction in which the tear tape extends) by pulling the end of the tear tape.

  Any appropriate resin film is used as a material for forming the packaging film. Preferably, a transparent resin film is used. As resin which forms a resin film, a polystyrene, a polypropylene, etc. are mentioned, for example. The resin film may be a stretched film. When the resin film is a stretched film, preferably, the tearing direction of the packaging film and the stretching direction of the stretched film are parallel to each other. Thereby, the packaging film can be easily torn along the tearing direction at the time of opening. Any appropriate resin film may be used as the material of the opening tape, and may be the same as or different from the material of the packaging film. The tear tape is preferably made of a material and thickness that is stronger than the packaging film so as not to be cut at the time of tearing.

C. Label A label is typically affixed to a packaging film for the purpose of displaying information about the package, and the above information is described. Examples of the information on the package include the name of the product which is the package, the manufacturer, the name of the raw material, the date of manufacture, and the bar code. Also, in the packaging material of the embodiments shown in FIGS. 4 and 5, the label may have the function of fastening the packaging film.

  In the illustrated example, the label is substantially rectangular, and has a recess and a notch on one side that first intersects with the tear of the packaging film when the package film is torn, but the outer shape of the label and the position of the recess and the notch are the same. It is not limited to. The outer shape of the label may be triangular or circular. Furthermore, the recess and the cut may be formed on a part of one side of the label, or may be formed over the entire circumference of the label. Furthermore, in the embodiment shown in FIG. 1, it may be formed on both end sides substantially orthogonal to the X direction of the label. This allows the label to be easily torn apart, regardless of whichever of the sealed ends of the packaging film is torn from either end.

  The shape of the recess is typically V-shaped as shown in FIG. 2 or U-shaped as shown in FIG. The length (depth) of the recess is, for example, 0.1 mm to 2 mm. The width of the recess is, for example, 0.1 mm to 2 mm.

  The incisions preferably extend in a direction parallel to the direction in which the packaging film is torn. That is, as shown in FIG. 1, when the packaging film is configured to be splittable along the direction (X direction) orthogonal to the direction in which the end extends, the cuts extend in the direction parallel to the direction If the packaging film is configured to be tear-crackable along the longitudinal direction of the opening tape as shown in FIGS. 4 and 5, the cuts extend in a direction parallel to the direction.

  The length of the cut may be appropriately set depending on the size and thickness of the label. The length of the cut is, for example, 0.5 mm to 5 mm. The longer the incision, the easier the label can be torn off at the time of opening, and the shorter the incision, the wider the area for displaying information on the package can be secured.

  The label typically includes a substrate, a pressure-sensitive adhesive layer formed on the substrate, and a heat-sensitive color-forming layer disposed on the opposite side of the substrate to the pressure-sensitive adhesive layer, and the pressure-sensitive adhesive layer It is stuck on the packaging film via The substrate is paper or a resin film. Information on the package is printed on the thermosensitive coloring layer.

  The packaging material of the present invention is suitably used for packaging food and the like.
