[The problem to be solved by the invention]

However, when a laminate having an outer resin film layer formed by an embossed film as shown in the above-mentioned Patent Document 2 is molded into a cup shape, the embossed film is stretched during the molding and the outer surface in a matt state is formed. Spots are produced, which may detract from the appearance. In addition, when an embossed film is used, there is a problem of high cost. In addition, when the laminate in which the outer resin film layer is formed by a film having a coating layer in a matte state as shown in the above-mentioned Patent Document 3 is molded into a cup shape, there is a problem that the coating layer is cracked or the coating layer is peeled off. In addition, there is also a problem of high cost when forming a coating layer in a matte state. In addition, when a laminated body in which a sheet in a matte state constitutes a surface layer as described in Patent Document 4 above is molded into a cup shape, since the compatibility of the polyethylene resin and the elastomer with the polypropylene resin is low, there is a problem in the molded body. The problem of whitening occurs on the surface.

Next, in the case of the laminate of the above-mentioned 1), as in a laminate in which the outer surface of the outer resin film layer is formed by embossing the film, it will not be stretched during molding to cause spots on the outer surface, and if Like a laminate in which the outer surface of the outer resin film layer is constituted by a film having a coating layer in a matte state, the coating layer does not have cracks or the coating layer is peeled off, so it is not cost-intensive. Therefore, by the laminated body for a molded container of the above-mentioned 1), a molded container having an outer surface in a matte state with good appearance can be obtained at low cost.

A predetermined display is displayed on the surface of the outer surface layer by forming a printed layer between the metal foil layer and the outer resin film layer, or by adding a coloring component to the outer resin film layer in the laminate for forming a container according to 2) above. or decoration, the molded container in which the laminate is molded has a better appearance.

With the layered product for forming a container of the above-mentioned 3), the above-mentioned effects can be more sufficiently ensured with respect to the layered product of the above-mentioned 1).

According to the molded container of the above 4), since it has an outer surface in a matte state with good appearance, it can be given a high-quality feeling.

According to the package of the above 5), the productivity is good, the cost can be suppressed, and whitening at the time of molding is suppressed, and the container having the outer surface in a matte state with a good appearance can be provided with a high-quality feeling.

Embodiments of the present invention will be described below with reference to the first to third figures.

The first figure shows the layer structure of the layered product for forming the container according to the embodiment of the present invention. The layered body (10) in the drawing has: a metal foil layer (11); and outer resin film layers (12), ( 12A)(12B). Moreover, the laminated body (10) of this embodiment has the inner resin layer (13) laminated|stacked on the surface which becomes the inner side of the container (2) among both surfaces of the metal foil layer (11). More specifically, in the laminate (10) shown in the first figure (a), the outer resin film layer (12) has a single-layer structure, and this layer (12) constitutes the extinction of the laminate (10). state of the outer surface layer (120). In addition, in the laminate (10) shown in the first figure (b), the outer resin film layer is composed of the first outer resin film layer (12A) that constitutes the outer surface layer (120) of the laminate (10) in a matte state. ), and a two-layer structure formed by a second outer resin film layer (12B) interposed between the first outer resin film layer (12A) and the metal foil layer (11).

The metal foil layer (11) plays a role of providing a barrier property for preventing the intrusion of oxygen or moisture to the laminated body (10) for forming the container. As the metal foil constituting the metal foil layer (11), aluminum foil, iron foil, stainless steel foil, copper foil, etc. can be used, but aluminum foil is preferably used. In the case of aluminum foil, either pure aluminum foil or aluminum alloy foil may be used, and either soft or hard may be used. For example, in the case of A8000 series ( In particular, the annealed soft material (O material) of A8079H or A8021H) is suitable for use because of its excellent formability. On one side or both sides of the metal foil layer (11), base treatment such as chemical conversion treatment is performed as required. Specifically, for example, on the surface of the degreasing metal foil, any one of the following aqueous solutions 1) to 3) is applied: 1) An aqueous solution of a mixture containing: phosphoric acid; chromic acid; and selected from fluorides At least one compound selected from the group consisting of a metal salt of a fluoride and a non-metallic salt of a fluoride. 2) An aqueous solution of a mixture comprising: phosphoric acid; at least one resin selected from the group consisting of acrylic resin, chitosan derivative resin, and phenol-based resin; and selected from chromic acid and chromium(III) At least one compound in the group consisting of salts. 3) An aqueous solution of the mixture, comprising: phosphoric acid; at least one resin selected from the group consisting of acrylic resins, chitosan derivative resins, and phenol-based resins; selected from chromic acid and chromium(III) salts at least one compound selected from the group consisting of; and at least one compound selected from the group consisting of metal salts of fluorides and non-metallic salts of fluorides. After that, by drying, chemical conversion treatment is performed to form a film. The film formed on the surface of the metal foil layer (11) by the above-mentioned chemical conversion treatment is preferably formed with a chromium adhesion amount (average single side) of 0.1 mg/m ² to 50 mg/m ² , especially 2 mg/m 2 ² ~ 20mg/m ² is better. The thickness of the metal foil layer (11) is preferably 30 to 200 μm, preferably 50 to 150 μm. By making it into the said range, sufficient barrier property and formability are acquired.

The outer resin film layers (12), (12A) and (12B) exhibit design properties for imparting a matte state to the outer surface of the molded container (1), and impart deep-draw moldability or convexity to the laminate (10) for the molded container. A formative role.

The outer resin film layer (12) or the first outer resin film layer (12A) constituting the outer surface layer (120) in the matte state is formed by a blown film, and the blown film is composed of a polyolefin resin and an olefin-based elastic film. It is formed of a resin composition whose main component is the body. Next, the glossiness (gloss value) of the outer surface (120a) of the outer surface layer (120) constituted by the above-mentioned layers (12) and (12A) is formed to be 0.5-30% (preferably 0.5-10 %). Here, "gloss" is the gloss (gloss value) measured according to JIS Z8741-1997 (specular gloss-measurement method, method 3 (incidence angle 60 degrees)). Among the above-mentioned resin compositions, the polyolefin resins include: block polypropylene resin (PP-B), homogeneous polypropylene resin (PP-H), random polypropylene resin (PP-R), high Density polyethylene resin (HDPE), linear low density polyethylene resin (LLDPE), low density polyethylene resin (LDPE), etc. Moreover, as an olefin type elastomer, an ethylene-propylene copolymer (EPR), an ethylene-butene copolymer (EBR), an ethylene-propylene-1-butene copolymer (EPBR), etc. are mentioned. About monomers other than ethylene, content is 5-40 mass %, and melting|fusing point is less than 90 degreeC. In addition, the outer surface layer (120) may contain a polyolefin component having a melting point of 135°C or higher. In addition, to the outer surface layer (120), in order to adjust the glossiness of the outer surface of the molding container (2), inorganic or organic fine particles may be added as necessary. For inorganic microparticles, the series include silicon oxide, aluminum silicate, barium sulfate, and the like. The series of organic fine particles include, for example, acrylic resin particles, polystyrene resin particles, and the like.

If the outer resin film layer is a plurality of layers (12A) (12B), the layers (12B) other than the outermost layer are made of polyolefin resins such as polypropylene resin (PP), polyethylene resin (PE), nylon 6 (PA6), Nylon 66 (PA66), MXD nylon and other polyamide resins (PA), polyethylene terephthalate resin (PET), polybutylene terephthalate resin (PBT), polyethylene terephthalate It is made of polyester resins (PEs) such as ester resins (PEN) and the like. The thickness of the outer resin film layers (12), (12A) and (12B) (if there are two or more layers, the total thickness) is preferably 5 to 100 μm, more preferably 15 to 80 μm. A lubricant may be added to the outer resin film layer (12) in order to obtain a molded container (2) having an appropriate depth. Examples of lubricants include fatty acid amides such as erucamide, stearic acid amide, and oleic acid amide, waxes such as crystal waxes and polyethylene waxes, and the like. In addition, instead of adding a lubricant, or in addition to the lubricant, a lubricant such as silicone oil or rapeseed oil may be coated on the surface of the layered body (10) during molding.

In the layered product (10) for forming a container according to the present invention, the films constituting the outer resin film layers (12), (12A) and (12B) are mainly composed of polyolefin resin and olefin-based elastomer. The resin composition of the components is a blown film formed by an inflation method. The above-mentioned blown film shows less deflection of the olefin-based elastomer in the longitudinal direction (M direction), which is the film flow direction, and in the transverse direction (T direction) perpendicular to the film flow direction. Therefore, when the laminated body (10) is molded, the interface between the polyolefin resin phase and the elastomer component is prevented from being peeled off due to stress, resulting in voids (voids), and transparency due to the difference in refractive index between the resin and the voids is prevented. deterioration, that is, whitening. Lamination of the metal foil layer (11) and the outer resin film layer (12) is performed by, for example, a dry lamination method through an adhesive layer (14). For the adhesive layer ( 14 ), for example, a two-part curing type polyester-polyurethane resin-based adhesive or a polyether-polyurethane resin-based adhesive is used. The thickness of the adhesive layer ( 14 ) is preferably set to 1 to 5 μm, and is more preferably set to 1 to 3 μm from the viewpoint of thinning and weight reduction of the layered body ( 10 ) for forming a container.

On the inner surface of the outer resin film layer (12) or the second outer resin film layer (12B), a printing layer (15) is formed entirely or partially by gravure printing or the like. By means of the printed layer (15), a predetermined display or decoration is presented on the outer surface of the shaped container (2). The printed layer (15) is not particularly limited, but in the sense of emphasizing the matte outer surface (120a) to give it a sense of luxury, it is preferable to make the base color a dark color such as black. Here, coloring components such as pigments may be added to the outer resin film layers (12), (12A) and (12B) instead of the printed layer (15).

The inner resin layer (13) constitutes the inner surface of the container (2) (including the upper surface of the flange portion (23)), and is made of, for example, a thermally fusible polypropylene resin (PP) film or polyethylene resin (PE) A general-purpose film such as a film, or a composite sheet in which these are bonded together. The thickness of the film or composite sheet constituting the inner resin layer (13) is preferably 100 to 500 μm, more preferably 200 to 400 μm. Lamination of the metal foil layer ( 11 ) and the film or composite sheet constituting the inner resin layer ( 13 ) is performed by, for example, a dry lamination method through an adhesive layer ( 16 ). For the adhesive layer ( 16 ), for example, a two-pack curing type polyester-polyurethane resin-based adhesive or a polyether-polyurethane resin-based adhesive is used. The thickness of the adhesive layer ( 16 ) is preferably set to 1 to 5 μm, and is more preferably set to 1 to 3 μm from the viewpoint of thinning and weight reduction of the layered body ( 10 ) for forming the container. In addition, the inner resin layer (13) can also be formed by a coating layer such as epoxy resin or shellac resin instead of the above-mentioned film or composite sheet.

The second figure shows, in order of steps, a package (4) of a package (4) formed by sealing the contents (C) such as food, using a molded container (2) formed from the above-mentioned laminate (10) and a lid (3). Production method.

First, the above-mentioned laminated body (10) is cut into a predetermined shape and size, and this is formed into a cup shape. The layered body (10) is formed by cold forming such as deep draw forming and extrusion forming. Thereby, a shaped container (2) as shown in the second figure (a) is obtained. The forming container (2) is provided with: a bottom wall (21); a peripheral wall (22) erected from the peripheral edge of the bottom wall (21); and a horizontal annular protrusion extending radially outward from the upper edge of the peripheral wall (22) Edge (23). In terms of the shape of the shaped container (2), there is a conical cylindrical shape that has a cross section such as a circle, an ellipse, an oval, a substantially square, and a substantially rectangular shape, and the diameter gradually increases as it goes upward, or Vertical cylindrical and so on. Moreover, the depth of the shaping|molding container (2) is normally formed in 15-50 mm. Almost no whitening was found on the outer surface of the molded container (2) formed of the above-mentioned layered body (10). This is based on the outer resin film layer (12) or the first outer resin film layer (12A) constituted by the outer surface layer (120) of the laminate (10) formed by the blown film made of the aforementioned resin composition, This effectively suppresses generation of voids (voids) due to the interface between the olefin-based resin phase and the elastomer component due to stress during molding.

Next, as shown in the second figure (b), after the forming container (2) is filled with contents (C) such as food, the bottom surface of the lid (3) is thermally welded to the top surface of the flange (23) of the forming container (2). the periphery of the. Here, for the cover (3), for example, a metal foil layer made of aluminum foil or the like is used; The heat-fusible resin film layer below the layer; and the outer resin film layer formed of polyester resin (PEs) film or polyamide resin (PA) film, etc. and laminated on the upper surface of the metal foil layer. In addition, the lid (3) is integrally formed with an unsealing tab (31) on a part of its outer peripheral edge so as to protrude outward from the flange (23) of the molding container (2) (see Figure 3). The means for thermally welding the lid (3) to the flange (23) of the shaped container (2) is not particularly limited, for example, the lower peripheral edge of the lid (3) is overlapped on the upper surface of the flange (23), and the The joining part is performed by heating for a predetermined time while applying a predetermined pressure by a hot plate heated to a predetermined temperature (for example, about 180° C.).

Next, the package (4) obtained in the above-mentioned steps is introduced into the autoclave sterilization apparatus (5), and the autoclave sterilization treatment is performed. This autoclave sterilization treatment step can also be used as a heat treatment step for eliminating whitening generated in a part of the outer surface of the molding container (2). That is, in the molding container (2) formed by molding the layered body (10) of the present invention into a cup shape, as described above, the outer surface layer (120) of the layered body (10) is constituted by the above-mentioned blown film. , thereby suppressing whitening on the outer surface, but in case of a part of the outer surface, especially in the corner of the boundary between the bottom wall and the peripheral wall where the deformation degree due to molding is large, even if the matrix of the olefin resin and the olefin When the voids (voids) generated at the interface of the elastomer are slightly whitened, the whitening can be completely eliminated by performing the heat treatment. The heating temperature of the packaging body (4) in this step is to form the outer surface layer (120) of the laminated body (10), that is, the single layer of the outer resin film layer (12) or the outer resin film layer of a plurality of layers. The temperature above the softening point of the resin of the outermost layer (in the case of the first figure (b), the first outer resin film layer (12A)). The heating temperature is more preferably a temperature that is equal to or higher than the softening point of the resin and less than the melting point. By setting the heating temperature to a temperature equal to or higher than the softening point of the resin, the deformation of the layered body (10) due to molding is alleviated, and the holes are easily filled. Moreover, by setting the heating temperature to a temperature lower than the melting point of the resin, the shape of the molding container (2) can also be maintained after heating. Specifically, it is set at about 80°C or higher, preferably about 100 to 180°C. The heating time is about 5 minutes to 3 hours. Among them, the heat treatment step may be performed by, for example, heat treatment in an oven, immersion treatment in warm water, or the like, in addition to the sterilization treatment by a sterilizer. In the case of heat treatment other than the autoclave sterilization treatment, only the molded container ( 2 ) may be subjected to heat treatment in the step before forming into the package body ( 4 ).

The third figure shows the package body (4) after sterilization in the autoclave. The package ( 4 ) of the drawing has a molded container ( 2 ) having an outer surface in a matt state with good overall appearance, with no whitening observed due to molding, and can give a sense of luxury to the user.
