Definitions

  • Labels such as pouches for filling semi-fluid or fluid contents such as foods, beverages, and detergents, and seal materials used as lids for cup-shaped or tray-shaped containers are printed with letters such as product names.
  • letters such as product names.
  • characters and designs are emphasized by, for example, making the printing three-dimensional.
  • a bag-like container with an embossed pattern is formed by forming a bag-shaped container using a soft packaging material and partially heating and cooling a predetermined portion of the bag-shaped container to form an embossed pattern.
  • a molding method has been proposed.
  • Patent Literature 1 there is a problem that it takes time for heating and cooling, resulting in poor productivity.
  • the compression molding is performed by compression-molding a laminated film having at least an inner film having a large innermost surface elongation and an outer film having a small elongation on the outer surface by a molding section in the thickness direction of the laminated film.
  • the formed processed portion is made of a material capable of exhibiting a wider elastic deformation region than a widest elastic deformation region in a plane direction of a film constituting the laminated film.
  • the forming section is installed on a forming roll of a rotary processing apparatus including an opposing forming roll and an anvil roll, 2.
  • the processing width of the forming part is 6 mm or more, 3.
  • the laminated film has a metal deposition layer between the inner film and the outer film, 4.
  • the stretched outer film is a stretched film made of nylon or polyester, and the stretched inner film is a film made of polyolefin, 5.
  • the molded portion is made of a polymer compound having a tensile modulus of 2.5 GPa or less, 6.
  • the compression amount in the compression molding is 30% or more and 50% or less with respect to the thickness of the laminated film; Is preferred.
  • the hologram-like appearance is formed on the overhang. It can be formed.
  • the three-dimensional processing method of the present invention is a laminate film having at least an inner film having a large innermost surface elongation and an outer surface film having a small elongation on the outer surface side, which is compression-molded in a thickness direction of the laminated film by a molding section. After the pressure is released, in the method of performing three-dimensional processing so that the compression molded portion protrudes to the outer surface side, the formed processed portion has an elastic deformation region wider than the widest elastic deformation region in the plane direction of the film constituting the laminated film.
  • the formed portion is made of a material capable of realizing an elastic deformation region wider than the widest elastic deformation region in the plane direction of the film constituting the laminated film to be used. This makes it possible to sufficiently stretch all the films constituting the laminated film. Therefore, when the laminated film has a two-layer structure of an inner film having a large elongation and an outer film having a small elongation, the elastic deformation region of the inner film having a large elongation is the largest among the films constituting the laminated film.
  • the part is formed from a material capable of exhibiting an elastic deformation region wider than the elastic deformation region of the inner film. The specific materials of the laminated film and the forming part will be described later.
  • the press processing device uses In the anvil and the rotary processing device, it is preferable that the surface of the anvil roll is formed of a material capable of exhibiting a wider elastic deformation region than the widest elastic deformation region of the film constituting the laminated film, similarly to the forming portion. is there.
  • the stretch amount of the laminated film is very large in order to increase the processing width of the overhang portion, particularly in a rotary processing device, since the laminated film is easily affected by the conveyance of the laminated film.
  • the three-dimensional processing method of the present invention may be a cold process in which compression molding is performed without heating the laminated film, a hot process in which the laminate film is heated to near the softening point temperature of the inner surface film, or a hot and cold process. It may be performed in an intermediate temperature range (warm). For example, when the inner film is polyethylene, at least the warming of the laminated film to a temperature of 35 to 80 ° C or the heating of a laminated film to a temperature of 80 to 100 ° C may be performed.
