Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an instant noodle package.

(Prior Art) In conventional instant noodles, dried, brittle, easy-to-eat noodles are enclosed in a plastic packaging bag in a naked state together with a flavoring agent, a dashi stock, and the like.

(Problems to be solved by the invention) Therefore, when the conventional one is packed in a box, transported, displayed, or carried by the purchase of a consumer, a part of the noodle is easily contacted by contact with other objects or pressing pressure. Only the clogs make small pieces of noodles.

Further, the noodles are deteriorated by the ultraviolet rays passing through the packaging bag, which is also a big problem from this point.

This invention eliminates the above-mentioned drawbacks, and provides an instant ramen package capable of preventing only noodles from being squeezed and preventing deterioration of noodles by ultraviolet rays.

(Means for Solving the Problems) That is, the present invention comprises a heat-shrinkable film for directly shrink-wrapping noodles and a packaging bag for enclosing the shrink-wrapped noodles. Both are instant ramen packages, characterized in that one of them is provided with a metal vapor deposition layer.

Next, the invention will be described with reference to the drawings.

FIG. 1 is a schematic view showing an example of a state in which noodles 10 are directly shrink-wrapped with a heat-shrinkable film 2. FIG. 2 is an explanatory view showing an example of a state in which shrink-wrapped noodles are enclosed in a packaging bag 30.

This invention is, so to speak, a double packaging of the interior and the exterior, and at least one of the interior and the exterior is provided with a metal vapor deposition layer, and the interior is a shrink-wrapped noodle directly. There is something.

The heat-shrinkable film 20 for directly shrink-wrapping the noodles 10 is a heat-shrinkable film made of polypropylene, vinyl chloride or the like,
To make this a metal vapor deposition layer, heat-shrinkable film is vapor-deposited with various metals such as Al and a protective layer is provided if necessary, or a metal such as Al is vapor-deposited on a plastic film such as polyester film. The metal vapor deposition film may be attached to the heat-shrinkable film. In addition, the heat-shrinkable film does not necessarily have to have the metal vapor deposition layer when the packaging bag is provided with the metal vapor deposition layer.

In order to directly shrink-wrap the noodles 10 with the heat-shrinkable film 20, the heat-shrinkable film may be formed into a tube and the noodles may be put in the shrink-wrapped film, or the whole shrink-wrapped with the heat-shrinkable film. Shrink wrapping may be performed by an appropriate method such as wrapping and shrink wrapping.

The packaging bag 30 that encloses the shrink-wrapped noodles is made of a heat-sealable film made of polyethylene or the like or a non-heat-sealable film such as polyester having a heat-sealable film or layer formed thereon.

In order to make the packaging bag 30 provided with a metal vapor deposition layer, metal vapor deposition is applied to a heat-sealing film, or a metal vapor deposition film which is metal vapor-deposited on a non-heat-sealing film such as a polyester film has a heat-sealing property. The films may be laminated or a heat-sealing layer may be formed.
If the heat-shrinkable film is provided with the metal vapor deposition layer, the packaging bag 30 does not necessarily have to be provided with the metal vapor deposition layer.

To enclose the noodles shrunk in the packaging bag 30, the shrink-wrapped noodles may be placed in the packaging bag 30 and heat-sealed to enclose the noodles.

In addition, not only the shrink-wrapped noodles are put in the packaging bag 30, but if necessary, dashi stock, flavors, etc. may be put together with the shrink-wrapped noodles. Included in the device.

(Examples and Comparative Examples) Commercially available instant noodles were used, and a drop test of the instant noodles was carried out using the packaging form as it was on the market and the instant noodle package of the present invention.

In the commercially available product, noodles molded in a rectangular parallelepiped shape were left naked, and were packaged in an outer casing of a printed plastic film together with a flavor and a sachet of dashi stock.

As the instant noodle package according to this invention,
After removing the outer bag of a commercially available product, first, the noodles that were left naked were laminated with the Al vapor-deposited 12 μm-thick polyester film and the Al vapor-deposited layer inside with the 70 μm-thick heat-shrinkable vinyl chloride film. It is made into a tube shape, which is then directly shrink-wrapped, and then this directly shrink-wrapped noodle is put together with a flavoring agent and a dashi element in a packaging bag made by extruding and laminating polyethylene on the Al vapor deposition layer surface of the Al vapor-deposited polyester film. And enclosed. The size of this packaging bag was the same as the outer bag of the plastic film which was commercially available.

The instant noodle package of the present invention thus obtained and the above commercially available product were dropped from a height of 50 cm, 1 m, and 2 m in a room where the floor was covered with vinyl tile, In each case, only the small amount of noodles was generated, but in the case of the instant noodle package of the present invention, only a very small amount of noodles was observed even in the drop test of 2 m. In the 1m and 50cm drop tests, no noodles were found at all.

(Effect of the Invention) This invention is that the noodles are directly shrink-wrapped by the heat-shrinkable film, so that the noodles are integrated and shrink-wrapped, and the noodles are partly packed in a box, transported, and displayed. , And when carried by a consumer, do not easily drop due to contact with other objects or pressure.

Moreover, since at least one of the heat-shrinkable film that directly shrink-wraps the noodles and the packaging bag that encloses the shrink-wrapped noodles has a metal vapor deposition layer, ultraviolet rays are cut by this metal vapor deposition layer, It is possible to prevent deterioration of noodles due to ultraviolet rays.
