Description

  The present invention relates to a sheet-like packaging material for packaging an absorbent article such as a sanitary napkin.

In many cases, absorbent articles such as sanitary napkins, panty liners (corimono sheets), disposable diapers, etc. are individually packaged and packaged on the market. And an absorbent article is taken out from a packaging material, is worn, and a packaging material is discarded.
By the way, before wearing of an absorbent article, wiping off the menstrual blood and excrement adhering to a wearer's skin with a wiping sheet is performed. At that time, it was necessary to prepare a separate wiping sheet, which was inconvenient.
In order to eliminate such inconvenience, a technique for bundling a wiping sheet together with an absorbent article in a packaging bag made of a packaging material is disclosed (for example, see Patent Documents 1 and 2 below).

Japanese Utility Model Publication No. 3-13130 Japanese Utility Model Publication No.2-1123

  However, in the techniques described in Patent Documents 1 and 2, before using the wiping sheet, an operation of opening the packaging bag and an operation of taking out the wiping sheet from the packaging bag are necessary, and the work efficiency is not high. . Also, when taking out and using individual products (or individual packaging forms), it is not normal to carry the entire packaging bag with you and you had to have a separate wiping sheet, so forget to take out the wiping sheet. Or hesitated to take it out and was not actually used.

  Therefore, the objective of this invention is providing the packaging material for absorbent articles excellent in the working efficiency of the wiping sheet.

  The present invention is a sheet-like packaging material for packaging an absorbent article, a part of which has a fiber shape, by providing a packaging material for absorbent articles that can be used as a wiping sheet, The above objective has been achieved.

  According to the packaging material for absorbent articles of the present invention, since the wiping operation can be performed using the wiping sheet simply by opening the packaging structure, the wiping sheet is excellent in work efficiency.

Hereinafter, the packaging material for absorbent articles of the present invention will be described with reference to the drawings based on the first embodiment which is a preferred embodiment thereof.

The packaging sheet 2 has a cutout portion 21, and the wiping sheet 3 is joined to the packaging sheet 2 so as to close the cutout portion 21.

Specifically, as shown in FIGS. 1 and 2A, the packaging sheet 2 needs to have an outer shape capable of packaging the absorbent article. In this embodiment, the absorbent article It has a rectangular shape having a length and a width that can be packaged.
The packaging sheet 2 has a rectangular cutout 21 at the center. The cut-out portion 21 has a size that is slightly smaller than the size of the wiping sheet 3, so that the wiping sheet 3 can be joined at the joining margin 22 of the peripheral portion of the cut-out portion 21 in the packaging sheet 2. It has become.
The length of the packaging sheet 2 is preferably 12 to 40 cm, and the width of the packaging sheet 2 is preferably 6 to 15 cm. The length of the cutout portion 21 is preferably 4 to 14 cm, and the width of the cutout portion 21 is preferably 3 to 9 cm.

As a material of the packaging sheet 2, a material used as a sheet for forming a packaging material for absorbent articles can be used without particular limitation. Examples thereof include polypropylene, polyester, polyethylene, polyvinyl alcohol, nonwoven fabric or paper having a thickness of 5 to 50 μm, or composite materials thereof.
The inner surface of the packaging sheet 2 is preferably subjected to a peeling treatment. The release treatment is performed by, for example, applying a release treatment agent to the entire inner surface of the packaging sheet 2, or a release member such as a release tape, release paper, release-treated nonwoven fabric, release-treated polyethylene laminated paper, or release-treated polyethylene film. This can be done by sticking.
As the release agent of the release treatment agent or release member, for example, a silicone resin type, a fluorine resin type, or an octadecyl isocyanate type is preferable. In particular, as the release treatment, a method of forming a thin film by applying a silicone resin-based release agent component and increasing the molecular weight by heat drying, ultraviolet irradiation or the like, or spraying with a spray is preferable.

The wiping sheet 3 preferably has a shape and size suitable for wiping. In this embodiment, as shown in FIG. 1 and FIG. It has a rectangular shape that is one size larger than that. The wiping sheet 3 is joined to the inner surface side (the inner surface side during packaging) of the packaging sheet 2 so as to block the cutout portion 21 at the joining margin 22 of the peripheral portion of the cutout portion 21. Therefore, a part (inward part) of the wiping sheet 3 is also exposed on the outer surface side (the outer surface side during packaging) of the packaging sheet 2. For joining the packaging sheet 2 and the wiping sheet 3, for example, a heat seal or a hot-melt adhesive is used.
From another viewpoint, the wiping sheet 3 is joined to one surface (inner surface) of the packaging sheet 2 without extending from the periphery of the packaging sheet 2.

The length of the wiping sheet 3 is preferably 5 to 15 cm, and the width of the wiping sheet 3 is preferably 4 to 10 cm.
In addition, the wiping sheet 3 may be joined to the packaging sheet 2 in a folded form, and in that case, in the folded form, the above-described preferable ranges of length and width are applied.
The ratio of the area of the wiping sheet 3 to the area of the entire inner surface of the packaging material 1 is preferably 40% or more, more preferably 50% or more, from the viewpoint of easy wiping.

Since the wiping sheet 3 is integrated with the packaging sheet 2, a dry (dry type) wiping sheet is preferably used.
The wiping sheet 3 is preferably a melt blown nonwoven fabric having a minute spatial structure or a spunlace nonwoven fabric having a minute spatial structure by a water flow or the like because of the good touch and collection properties.
In the melt blown nonwoven fabric, in order to improve the cleaning effect, a surfactant may be blended to such an extent that it does not feel sticky. From the viewpoint of flexibility, it is preferable to use polyethylene or polypropylene resin.

  As the spunlace nonwoven fabric, it is preferable to use a synthetic fiber of polypropylene or polyester from the viewpoint of improving the collection property due to its bulkiness, and from the viewpoint of collecting a liquid material, hydrophilic fibers such as pulp and rayon are blended. From the viewpoint of enhancing the wiping effect, it is preferable to use fibers such as split fibers. In particular, when fine fibers are blended in the vicinity of the surface in contact with the skin and bulky fibers and hydrophilic fibers are blended inside the layer, the wiping property and the trapping property are excellent. In addition, when a water-soluble or water-swellable material is blended (for example, one component of the split fiber is polyvinyl acetate) and the fibers are entangled, it is more preferable because water disintegration can be obtained. .

  According to the packaging material 1 of the first embodiment, for example, the sanitary napkin N is placed on one surface of the packaging material 1 and folded into a predetermined folded shape as shown in FIG. Moreover, a packaging form can be maintained using the fastening tape 4 fastened to the longitudinal direction one end part of the packaging material 1 (packaging sheet 2). Moreover, the longitudinal direction both sides 11 of the packaging material 1 are weakly sealed by heat sealing or the like and sealed.
