Although the fastener 15 having a structure for fitting and is used,
The fastener 15 having such a structure has a problem in that the resealability is poor and the cost is increased due to the following reasons. That is, the fastener 15 is usually supplied in a state in which the convex piece 16 and the concave piece 17 are fitted to each other, and is easily deformed so that the fastener 15 is transported to the bag manufacturing process in a looped state. As a result, the fastener 15 is deformed, and when attached to the bag, the engagement between the convex piece 16 and the concave piece 17 becomes poor,
Resealability deteriorates. Further, the fastener 15 is wound in a loop shape and is bulky, which is inconvenient for transportation,
Further, the fastener 15 has a winding tendency, and even if it is cut to a predetermined length, it has an arc shape, so that it is difficult to attach the fastener 15 together, which increases the cost.

However, only the end of each tape on the side where the tape is to be opened is attached to the inside of the bag body, and the other end side of each tape is arranged on the opposite side of the part where the tape is to be opened, and at least the inner surface of one tape is attached. , Self-adhesiveness is provided.

には必ずしも離型紙を貼る必要がない。As the tape, a tape having a self-adhesive resin layer laminated on one surface of a substrate is used. As the base material, the inner surface side of the packaging material forming the bag body is formed of a material having a heat-welding property, and when one end portion of the base material is heat-welded to the inner surface of the packaging material, A film having a heat-welding property with the inner surface of the packaging material, such as a film of polyethylene resin or polypropylene resin, is used. Further, when one end of the base material is adhered to the inside of the bag body, a base material to which an adhesive is applied only to one end portion of the other surface is used. As this adhesive, one having stronger adhesive ability than the self-adhesive resin layer laminated on one surface of the substrate is used. Further, for the base material, for example, in the case of a bag body having a length of 200 mm and a width of 150 mm,
A width of about 7 to 10 mm is used. The resin layer having self-adhesiveness is formed of an ethylene / vinyl acetate copolymer resin, an ethylene / vinyl acetate copolymer resin mixed with 15% by weight or less of vinyl acetate resin, a rubber-based resin as a base material. It is formed by coating. Until the bag-making process, this tape is sent in a rolled-up state with release paper attached to the self-adhesive resin layer side, but since it is a film, it fits the convex and concave pieces together. Unlike a fastener wound in a wound state, it does not have a winding habit, and even if it has a winding habit, it does not hinder the bag making process. Note that, for example, even when a tape having an adhesive applied to one end of the other surface is used as the tape, when the tape is sent to the bag manufacturing process,
Since the area to which the adhesive is applied is extremely small, it is not always necessary to attach release paper to this area.

にフリー状態に配置されている。Prior to the bag-making process of the bag body, a tape is attached to the packaging material for manufacturing the bag body, which is cut into individual sheets, in the vicinity of the planned opening portion of the inner surface of the bag body. .. This tape is cut into a length that extends over the entire length of the predetermined opening portion of the bag body, and is used as a set of two strips. Of the two tapes, at least the tape having self-adhesiveness is stretched in the vicinity of the portion to be opened with the resin layer having self-adhesiveness disposed inside, and the tape on the other surface of each tape is Only one end is attached inside the bag body. When the inner surface of the bag body and the base material of the tape are made of a material capable of being heat-welded in advance, the tape is adhered in a streak shape to one end of the other surface of the base material of the tape. When the part is coated with an adhesive, it is strongly bonded by the adhesive. The other end of the tape attached to the planned opening portion inside the bag body is arranged in a free state on the side opposite to the planned opening portion.

ても、高い再密封性を維持することが可能となる。In the present invention, in the vicinity of the planned opening portion of the bag body,
When there is a notch for opening and a part with a cut line in addition to the resealing part with a self-adhesive tape in one set of two articles, when the contents are first taken out from the bag, the notch or Cut along the cut line to open it, then open the resealing section formed by a set of two tapes and take out the contents.
After retrieving the necessary amount of contents and then resealing, a self-adhesive property applied to the inner surface is used to adhere a set of two tapes. In this resealing portion with a set of two tapes, only one end portion of the outer surface, which is the other surface of each tape, on the side of the planned opening portion is adhered to the inner surface side of the bag body, and the other end is the portion of the planned opening portion. The two tapes are arranged on the opposite side, and the two tapes are closely adhered to each other on the inner surface. As a result, the two strips of tape that are in close contact with each other act as if they were check valves, and in close contact with a wide surface contact, they exhibit high sealing performance, and the contents are repeatedly taken out. It becomes possible to maintain high re-sealing property even if the re-sealing portion of the strip tape is repeatedly used.

いので、大幅なコストダウンを図ることができる。Further, in the present invention, even if the tape used for the resealing portion is supplied to the bag making process in a looped state, there is no concern that it is bulky and difficult to transport, and the tape is a film. Because of this, there is no winding habit, and even if a winding habit is attached, the winding habit can be easily removed and affixed to the bag body, and the attaching property is good, so that a significant cost reduction can be achieved.

Each time the tape was taken out one by one, it was resealed by utilizing the self-adhesiveness of the tape 5 in two sets. As a result, there was no change in quality between the first content 10 removed and the last content 10 removed after 28 days. This is because a set of two tapes 5 for resealing are adhered to each other and are housed inside the bag body 1 in a state of being cross-linked in a substantially Y-shape, and function as if it were a check valve. In addition, since the surfaces are in close contact with each other with a wide surface contact, the resealing property is improved.

The adhesive 9 was applied to one end of the surface of the base material 6 in a stripe shape with a width of about 1 mm. Since the width of the coated surface of the adhesive 9 is as narrow as about 1 mm, it is not necessary to attach release paper to this part, and it is possible to wind it in a loop shape and supply it to the bag making process, and rewind it there before use.
