Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an oxygen absorber packaging bag. For more information,
The present invention relates to an oxygen scavenger packaging bag used for storing foods and the like.

The oxygen scavenger bag is a package in which a composition that absorbs oxygen is packaged, and has been used for preserving foods and the like by enclosing it in a non-breathable bag with the foods and the like. Recently, it is used together with an oxygen detector to detect the presence or absence of oxygen, and used for preservation of food etc. while checking whether the inside of a non-breathable bag enclosing food etc. is anoxic. It became so. Since the oxygen detector changes its color depending on the presence or absence of oxygen, it is possible to confirm whether or not the food storage system is in an oxygen-free state. By using this oxygen detector together with the oxygen absorber, it is possible to reduce the increase in the oxygen concentration in the sealed system due to pinholes in the air-impermeable bag, inadequate sealing, or a decrease in the oxygen absorbing capacity of the oxygen absorber. You can check.

However, since the oxygen scavenger and the oxygen detector are conventionally packaged separately, enclosing the oxygen absorber bag and the oxygen detector bag in a food packaging bag is time-consuming and requires poor workability. Was. Further, even in a food packaging bag, since the oxygen detector bag is small, it is difficult to find it, and it often takes time to detect the presence or absence of oxygen.

[Problems to be solved by the invention]

The object of the present invention is to solve the above-mentioned problems of the prior art, to simplify the packaging operation in a packaged food or the like using an oxygen absorber, and to easily confirm the oxygen detector in the packaging bag of the food or the like. That is.

[Means for solving the problem]

Means to solve the above-mentioned problem is that the oxygen absorber bag
The oxygen detector packaging sheet is formed by attaching an oxygen detector sheet formed by forming a spot pattern of the oxygen detector on the base sheet. In addition, oxygen detection is performed on the oxygen-absorbing bag and on the tape-shaped base sheet. That is, an oxygen-sensing agent sheet formed by continuously forming a plurality of spot patterns of an agent is attached to form an oxygen-absorbing agent packaging bag.

In the above solution, the oxygen scavenger bag is obtained by enclosing a composition that absorbs oxygen in a breathable packaging material.
Usually, for example, a single sheet (paper, nonwoven fabric, microporous film, perforated plastic film, non-perforated plastic film, or the like alone or a laminate thereof) having at least one surface having a heat-adhesive property is bonded to the heat-adhesive surface. A three-sided seal bag in which a deoxidizer is put in while folding in two with the inside facing in and the three non-folded peripheral edges are sealed, or two sheets of the same or different materials similar to those described above are opposed to each other to remove It is in the form of a four-side seal bag or the like in which an oxygen agent is disposed and the four sides of the periphery are sealed.

Further, as the oxygen detecting agent sheet, one obtained by printing, applying, or impregnating a base sheet such as paper or nonwoven fabric with a composition that changes color depending on the presence or absence of oxygen is used.

The size of the base sheet is at least smaller than the area of the oxygen-absorbing agent packaging bag, and any shape such as a rectangle, a square, a circle, a triangle, or a tape can be used. Further, the oxygen detecting agent composition is printed, applied or impregnated as a spot pattern on a base sheet to be used, and the shape of the spot pattern is rectangular, square, round, triangular,
Any type may be used, but it is preferable to form a round or square spot pattern on the tape-shaped base sheet from the viewpoint of the aesthetic appearance and the ease of finding the oxygen detector sheet.

As an aspect of attaching the oxygen detector sheet to the oxygen absorber packaging bag, a tape-shaped or emblem-shaped oxygen detector sheet is attached to a part of the surface of the oxygen absorber packaging bag, preferably at the center. In special cases, it can be attached to the end of the oxygen scavenger packaging bag.

[Action]

 The oxygen scavenger packaging bag of the present invention operates as follows.

Since the oxygen absorber packaging bag of the present invention integrates the oxygen detector sheet and oxygen absorber packaging bag, the oxygen detector can be put into the food packaging bag at the same time as the oxygen absorber bag, which improves the work efficiency. In addition, the food packaging bag containing the oxygen scavenger packaging bag of the present invention can easily find an oxygen detector, and can easily detect an oxygen concentration abnormality in the food packaging bag.

〔Example〕

 An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic view of one embodiment of the oxygen-absorbing agent packaging bag of the present invention, in which a tape-shaped oxygen-sensing agent sheet formed by continuously forming a plurality of round spot patterns of the oxygen-sensing agent is attached. FIG. 2 is a sectional view taken along line XY of FIG. It is attached with an oxygen absorber bag 4 containing an oxygen absorber 5, an oxygen detector sheet 2, an oxygen detector part 1, and an adhesive 3.

FIG. 3 is a schematic view of another embodiment of the oxygen-absorbing agent packaging bag of the present invention, in which a square oxygen-sensing agent sheet formed by forming a round spot pattern of the oxygen-sensing agent is attached.
The figure shows a sectional view taken along the line XY in FIG. It is attached with an oxygen absorber bag 4 containing an oxygen absorber 5, an oxygen detector sheet 2, an oxygen detector part 1, and an adhesive 3.

The packaging material of the oxygen scavenger bag 4 is preferably made of at least two or more laminated materials, and the inner layer forming the sealing surface is preferably made of a material having a lower softening point than the outer layer. For example, the inner layer is preferably made of a single film such as polyethylene, polypropylene, ethylene-vinyl acetate copolymer, or ionomer, or a composite film of the above materials. The outer layer is preferably made of a single film such as polyester such as nylon or polyethylene terephthalate, polypropylene, paper, or a composite film of the above materials. These can be provided with air permeability by providing small holes as necessary, or using at least a part of a nonwoven fabric, a microporous membrane or the like. An adhesive layer having a low softening point may be provided between the inner layer and the outer layer, or an adhesive material may be laminated on the inner layer or the outer layer in advance.

The attachment of the oxygen detector sheet 2 to the oxygen absorber bag 4
This is achieved by superposing the oxygen scavenger bag 4 and the oxygen detector sheet 2 and thermally bonding them from the outside with, for example, a heat roll or a heat bar, applying an adhesive, or bonding with a double-sided adhesive tape.

[Effect of the invention]

In the present invention, the oxygen detector can be put in the food packaging bag at the same time as the oxygen scavenger bag, and the work efficiency can be improved. In addition, the food packaging bag containing the oxygen scavenger packaging bag of the present invention can easily find an oxygen detector, and thus can easily detect an oxygen concentration abnormality in the food packaging bag.
