Description

[Detailed Description of the Invention] <Technical Field> This invention relates to a packaging sheet, and more specifically, to a packaging sheet for simply and inexpensively packaging foodstuffs and other stored items.

<Background and prior art> Traditionally, in supermarkets, etc.
BACKGROUND ART Food products and the like are stored in trays made of foam sheets, and if necessary, the whole thing is wrapped and displayed.

The above-mentioned trays are used as a simple packaging method because they can be mass-produced, are relatively inexpensive, and have good cushioning properties, but there is an increasing need to reduce packaging costs. It is something that In addition, according to the above-mentioned tray, it is necessary to prepare and select various items depending on the size and shape of the stored items, which is inconvenient in terms of use and inventory management. There were also disadvantages in that blood juices, dew, etc. accumulated in one place accelerated deterioration of the quality of the stored items, and the stored items tended to be biased to one side and crushed.

Furthermore, according to the above-mentioned wrap packaging, blood and juices from the stored items are likely to leak out, so it may be necessary to further wrap the entire item in a plastic bag provided at the store, and the time and effort required for wrap packaging is also troublesome. It was something.

<Purpose> This invention was made in view of the above problems, and the purpose is to provide a packaging sheet that allows easy and suitable packaging and further reduces packaging costs. do.

<Structure> The structure of the packaging sheet of this invention to achieve the above object is that a long multilayer sheet formed by laminating a cushioning sheet and a nonwoven fabric sheet has a long layer on the surface of the nonwoven fabric sheet side. It is made by laminating transparent synthetic resin sheets in a non-laminated state.

<Example> Next, an example of this invention will be described below with reference to the drawings.

As shown in FIG. 1, the packaging sheet A of this invention is different from the multilayer sheet 1 mainly made of a long belt-shaped cushioning sheet a such as a polyethylene foam sheet, for example, a polyethylene resin sheet, a high-impact A long transparent synthetic resin sheet b (hereinafter, the term "sheet" is used to include a film) such as a polystyrene resin sheet is stacked in a non-laminated state, and the entire sheet is usually wound as shown in the figure. It is provided as a rolled sheet.

The multilayer sheet 1 is a flat cushioning sheet a laminated with a nonwoven fabric sheet c,
In the case of the figure, the nonwoven fabric sheet c is laminated on the surface side of the cushioning sheet a, and the lamination method may be either full-area lamination or partial lamination. In addition, the multilayer sheet 1 and the transparent synthetic resin sheet b
At least one side portion 12 of both side portions 11 and 12 along the longitudinal direction is joined to each other by heat fusion or the like.

According to the packaging sheet A having the above structure, fish, vegetables, or other stored items S are inserted between the transparent synthetic resin sheet b and the multilayer sheet 1 by unrolling a predetermined length from the roll at the packaging site. Then, in this state, the multilayer sheet 1 and the transparent synthetic resin sheet b, excluding the joined one side part 12, are heat-sealed in a sealed form or in a bag form with an opening, and at the same time, the unrolled side and the transparent synthetic resin sheet b are sealed. By separating, it is possible to easily package the stored item S according to its size (see Fig. 2). Also,
A tear-openable bag is formed in advance from the above-mentioned packaging sheet A, and the stored item S is inserted into the bag from the unsealed part, and if necessary, the unsealed part is heat-sealed to complete the packaging. You may do so. In either case, the stored items S can be visually viewed through the transparent synthetic resin sheet b, and the cushioning sheet a can ensure cushioning properties, shape retention properties, and heat insulation properties. Moreover, since the nonwoven fabric sheet c can absorb the blood juices of the stored items S, it is possible to avoid the inconvenience that blood juices accumulate during display etc. and the quality deterioration of the stored items S is accelerated. Furthermore, since sufficient frictional resistance can be ensured by the nonwoven fabric sheet c, it is possible to avoid the inconvenience of the stored items S moving once packaged during transportation, etc., or that multiple stored items S may be unevenly crushed. can. In addition, the nonwoven fabric sheet c can also provide a reinforcing effect for the cushioning sheet a.

Next, the embodiment shown in FIG. 3 has the same basic structure as the embodiment shown in FIG.
It is characterized by the formation of . In this embodiment, the protrusions 2 can strengthen the bending resistance in the direction perpendicular to the protrusions 2, and can also store excess blood or the like between the protrusions 2. In addition, the embodiment shown in FIG. 4 is a case where the protrusions 2 are arranged on the opposite side of the nonwoven fabric sheet c, and in this embodiment as well, the nonwoven fabric sheet c can prevent the accumulation of blood, fluids, etc. The reinforcing effect of the strips 2 can also be provided.

Furthermore, as the cushioning sheet a, it is also possible to use a foamed sheet with a corrugated cross section.
(see figure), in this case as well, as in the above embodiment, the nonwoven fabric sheet c can prevent blood juice etc. from accumulating, and excess blood juice etc. can be stored in the troughs.

On the other hand, in the embodiment shown in FIG.
is constructed from a transparent sheet in which a large number of air pockets 4 are bulged, and the air pockets 4 are arranged on the side of the nonwoven fabric sheet c. In this embodiment as well, the cushioning sheet a can ensure good cushioning and heat insulation properties, as well as a certain degree of shape retention. In addition, the nonwoven fabric sheet c can prevent blood fluids and the like from accumulating, and can also collect excess blood fluids and the like between the air pockets 4. In the above embodiment, it is of course possible to arrange the air pocket 4 on the opposite side of the nonwoven fabric sheet c (see FIG. 7).

A heat-shrinkable sheet can also be used as the transparent synthetic resin sheet b. In this case, by heat-shrinking the heat-shrinkable sheet and bringing it into close contact with the stored items S, the stored items S can be further tightened. The multilayer sheet 1 can be packaged in a reliable immovable state, and the multilayer sheet 1 can be made to follow the stored items S to some extent by the tensile action caused by heat shrinkage.

In any of the above embodiments, it is also possible to laminate the non-woven fabric sheet c on the back side of the cushioning sheet a or on both the front and back surfaces, and in this case, the frictional resistance due to the non-woven fabric sheet c, Since the slip prevention effect on the back side of the multilayer sheet 1 is obtained, it is possible to avoid the inconvenience of slipping and falling when the stored items S are stored and stacked in multiple stages.

Further, as shown in FIG. 8, by laminating a nonwoven fabric sheet c on one side of the cushioning sheet a and laminating, for example, a textured non-foamed sheet d on the other side, the reinforcing effect can be further enhanced. The textured non-foamed sheet d can also prevent slips on the back surface of the multilayer sheet 1.

Furthermore, both sides 11 and 12 along the longitudinal direction may be joined to form a tube shape, or both sides 11 and 12 may not be joined and the transparent synthetic resin sheet b and the multilayer sheet are formed. 1
In some cases, it may be carried out in a state where the two can be completely separated.

On the other hand, in addition to constructing the cushioning sheet a with a urethane foam sheet, the transparent synthetic resin sheet 2 can also be constructed with vinyl chloride, for example, by changing the combination of both materials. In addition, the transparent synthetic resin sheet b may be formed to be wider than the multilayer sheet 1, and especially in this case,
Even bulky items can be stored without any problems.

<Effects> As described above, since the packaging sheet of this invention is entirely composed of sheet material, it can be provided as a packaging material that is easy to manufacture and inexpensive.

In addition, the cushioning sheet can ensure good cushioning properties and shape retention, and the cushioning sheet can also be reinforced with a nonwoven fabric sheet. Moreover, since the items stored inside can be seen through the transparent synthetic resin sheet, it is particularly suitable as a simple packaging material for display purposes. Furthermore, since it can be cut to any size depending on the items being stored, it becomes a packaging material with a wide range of uses. No effort is required.

Moreover, the non-woven sheet prevents the accumulation of blood and juices.
It is possible to exhibit effects such as preventing movement of stored items.

Therefore, it has the unique practical effect of being able to be easily and suitably packaged and contributing to further reduction in packaging costs.
