【発明の詳細な説明】 ［産業上の利用分野］ 本発明は、雄条と雌条から成る咬合部を形成した所謂ジ
ッパーテープ及びこのジッパーテープ付袋の製造方法に
関するものである。Description: TECHNICAL FIELD The present invention relates to a so-called zipper tape in which an occlusal portion including a male thread and a female thread is formed, and a method for manufacturing the bag with the zipper tape.
［従来の技術］ 従来のジッパーテープは、ポリエチレン（ＰＥ）又はポ
リプロピレン（ＰＰ）単体で、その咬合部とテープ部分
で構成されている。[Prior Art] A conventional zipper tape is made of polyethylene (PE) or polypropylene (PP) alone and is composed of an occlusal portion and a tape portion.
このためジッパーテープを袋本体フィルムの開口部位内
に取り付ける場合に、袋本体フィルムがＰＥ又はＰＰで
ある場合はそのまま直接ヒートシールが可能であるが、
袋本体フィルムがナイロンとかポリエステル或いはアル
ミ箔等の場合には、この内面にジッパーテープ側と相溶
性を有するフィルムを貼り合わせている。Therefore, when the zipper tape is attached inside the opening portion of the bag body film, if the bag body film is PE or PP, heat sealing can be directly performed as it is.
When the bag body film is nylon, polyester, aluminum foil, or the like, a film compatible with the zipper tape side is attached to the inner surface of the bag body film.

ープ１、1aのテープ部分Ａ・Ｂを袋本体フィルム３、3a
側にヒートシールしており、このヒートシールしている
間はテープとフィルムの走行は止っている。FIG. 2 shows a conventional method for manufacturing a bag with a zipper tape, in which 1 and 1a are zipper tapes, 2 is an occlusal part,
3, 3a are bag body films, 4 and 4a are bag body films 3,
Tapes A and B of the zipper tapes 1 and 1a with the separators 5 and 5a, which are the same film for fusing as the zipper tapes 1 and 1a that are attached to the inside of 3a, 5 and 5a are separators, and 6 and 6a are sealers. The tape portions A and B of the zipper tapes 1 and 1a are squeezed by the sealers 6 and 6a while preventing them from being fused to each other and the bag body films 3 and 3a.
It is heat-sealed to the side, and running of the tape and the film is stopped during this heat-sealing.
［従来技術の問題点］ このため、次のような問題がある。[Problems of Prior Art] Therefore, there are the following problems.
ａ．ラインの流れが間欠的となり、生産性が上らない。a. The flow of the line becomes intermittent and productivity does not rise.
ｂ．ジッパーテープのテープ部分Ａ・Ｂが薄いとヒート
シール時にこのテープ部分Ａ・Ｂに熱が通って溶融して
しまい、咬合部が変形したりして機能しなくなる心配が
ある。そこで、従来はＰＥで150 〜200 μ、ＰＰで120
〜180 μの厚みを確保していたが、ジッパーテープ部分
Ａ・Ｂの厚みが増すと、袋のサイドシールを行う際に、
このジッパーテープ部分Ａ・Ｂの厚み分サイドシール用
のシーラーの温度を上げなければジッパーテープ部分Ａ
・Ｂにおいてシールが不完全となり、ピンホールが発生
したりするという問題がある。一方、このようにジッパ
ーテープ部分Ａ・Ｂのためにシーラーの温度を上げる
と、他の部分においては過剰熱となり、溶融過多の問題
が発生する。b. If the tape parts A and B of the zipper tape are thin, heat may pass through the tape parts A and B during heat sealing and the melted parts may deform the occlusal part, causing a malfunction. Therefore, conventionally, PE is 150 to 200 μm and PP is 120 μm.
Although a thickness of ~ 180 μ was secured, when the thickness of the zipper tape parts A and B increased, when performing side sealing of the bag,
If the temperature of the side seal sealer is not increased by the thickness of the zipper tape parts A and B, the zipper tape part A
-In B, there is a problem that the seal becomes incomplete and a pinhole is generated. On the other hand, when the temperature of the sealer is raised due to the zipper tape portions A and B as described above, excess heat is generated in other portions, and a problem of excessive melting occurs.
ｃ．ジッパーテープは材質的にヒートシール可能なＰ
Ｅ、ＰＰ等で作られているため、耐熱性に劣り、例えば
電子レンジ等で解凍或いは調理する食品用袋には用いる
ことができない場合がある。c. Zipper tape can be heat-sealed due to its material.
Since it is made of E, PP, etc., it is inferior in heat resistance and may not be used for a food bag that is thawed or cooked in a microwave oven, for example.
ｄ．その他、ジッパーの外側に直接融着用のフィルムを
貼り合わせ、これと袋本体側のフィルムを融着するよう
にした技術（実開昭５９−１０２４０号公報及び実開平
１−１３４０３７号公報）が公知であるが、このように
ジッパーテープの外側に直接融着用のフィルムを貼り合

り薄く形成すると、ヒートシール時の熱の影響を無視で
きなくなり、ジッパー性能が低下することから、薄さに
は限界がある。しかし、強度的には薄くてもよいものも
多い。d. In addition, a technique is known in which a film for fusing is directly attached to the outside of the zipper, and the film on the bag body side is fusing with the film (Japanese Utility Model Publication No. 59-10240 and Japanese Utility Model Publication No. 134037). However, when the film for fusion is directly attached to the outside of the zipper tape in this way, if the thickness of the zipper tape parts A and B is made too thin, the effect of heat during heat sealing cannot be ignored. However, there is a limit to the thinness because the zipper performance is reduced. However, many of them may be thin in terms of strength.
