Definitions

  • the present invention relates to a decorative laminated film in which characters and designs are formed by printing and convex portions, and more specifically, a decorative laminated film excellent in design properties in which the three-dimensional effect of characters and designs is emphasized, and
  • the present invention relates to a bag-like container having a decorative laminated film and a sealing material.
  • Characters such as product names are used for seals used as lids for pouches and cups and trays for filling semi-fluid or fluid contents such as foods, beverages and detergents.
  • characters and designs are made to stand out by making printing three-dimensional.
  • Patent Document 1 a convex portion formed in accordance with an embossed pattern is heated to a predetermined temperature, brought into contact with the surface of the soft wrapping material, and the soft wrapping material is partially shrunk to rise outside.
  • a bag-like container having an embossed pattern has been proposed.
  • an embossed pattern with a texture different from the pattern by printing is formed on the bag-shaped container, but the synergistic effect by the combination of the embossed pattern and printing has not been obtained, and the design I was still not satisfied with the sex.
  • Patent Document 2 a laminated film formed by laminating a plurality of films having different coefficients of thermal expansion, heating and pressing a mold for character or mark, and expanding the shape of the mold, Alternatively, a laminated film in which a foil is transferred to a mold shape and bulged has been proposed. In this laminated film, a character mark itself can be bulged to form a three-dimensional character or mark.
  • an object of the present invention is to provide a decorative laminated film excellent in design, in which a decoration is formed by a print design and convex portions without impairing the function as a packaging material.
  • Another object of the present invention is to provide a bag-like container and a sealing material having a decoration in which characters and designs are three-dimensionally emphasized and excellent in design.
  • the characters and / or designs are formed on the laminated film composed of at least the inner surface film and the outer surface film by the convex portions protruding on the printed and outer film side
  • the characters and / or At least a part of the design has a metallic luster, and at least one of hue, brightness, saturation, or glossiness is different from the region excluding the character and / or design, and at least a part of the character and / or design
  • a decorative laminated film is provided in which convex portions are formed along the same.
  • the metallic luster of the character and / or design is derived from a vapor deposition layer formed on the outer surface film or a printed layer constituting the character and / or design, 2.
  • the character and / or design and the area excluding this have a light / dark difference, and the convex part is formed in a relatively bright part, 3.
  • Printing that emphasizes the shadow is applied to the part that becomes a shadow when light is irradiated from one direction to the formation part of the convex part, 4).
