AI Technical Summary

Problems solved by technology

However, retort food in bag-like containers usually needs to be transferred to plates, bowls, etc. after cooking, and is often unpopular, especially in single-person households, due to the time it takes to wash the dishes
In addition, recently, natural disasters such as earthquakes, typhoons, and floods have occurred frequently around the world, but tableware may not be available in disaster areas and evacuation areas.

manufacture example 1

[0115] Both sides of a 120 μm thick aluminum foil (A8079H-O material) were treated with a chemical conversion treatment solution containing phosphoric acid, acrylic resin, chromium (III) salt compound, water, and alcohol to prepare a treated aluminum foil with a base layer formed thereon. It should be noted that the amount of chromium attached to each side is 10mg / m 2 . Next, a PU adhesive was applied to one side of the treated aluminum foil so that the dry film thickness became 3 μm, and a film formed of HPP1 (300 μm thick, manufactured by T-die method) was bonded. Next, apply a PU adhesive on the other side of the treated aluminum foil so that the dry film thickness becomes 3 μm, and attach a total of 30 μm including a 4.5 μm thick rPP layer, a 21 μm thick bPP layer, and a 4.5 μm thick rPP layer. A thick unstretched three-layer coextruded polyolefin film from which a laminate is made. Next, this laminated body was aged at 40 degreeC for 8 days, and the aluminum laminated p...

manufacture example 2～3

[0117] In the same manner as in Production Example 1, except that a film formed of HPP2 (300 μm thick, produced by T-die method) or a film formed of HPP3 (300 μm thick, produced by T-die method) was used instead of the film formed of HPP1 Operation, making aluminum laminate packaging materials B and C.

Abstract

The present invention relates to a molded container and a package for containing fat-containing food, and provides a molded container which is not easy to be colored and tasty even if processed food containing a large amount of fat such as curry and stewed food is stored for a long period of time. The container is used in which a metal laminate packaging material (10) is molded such that a thermally fusible resin layer (10a) is formed as an inner surface, and the metal laminate packaging material (10) is obtained by laminating a thermally fusible resin layer (10a) formed from a homo-polypropylene film, a barrier layer (10c) formed from a metal foil, and a protective resin layer (10d) formed from a synthetic resin film in the stated order.

Description

technical field [0001] The present invention relates to a molded container suitable for storing fat-containing foods, and a package using the molded container. In this specification, unless otherwise specified, aluminum includes pure aluminum and aluminum alloys. Background technique [0002] Since ancient times, cans and bottles have been used for long-term preservation of processed foods. However, the bottle is heavy and easily shattered, and there is a risk of injury to the can due to the notch after opening, so there are problems in terms of portability and handling. Therefore, molded containers using light and flexible laminated packaging materials are widely used. [0003] As a laminated packaging material, a metal laminated packaging material (so-called high-barrier film) obtained by laminating both sides of a metal foil with a synthetic resin film is known. In addition, among metal laminated packaging materials, an aluminum laminated packaging material in which a ...
