Description
〔長手方向に延びる縦シール部〕
本発明の充填包装体に備えられる筒状の包装フィルムは、長手方向に延びる縦シール部を備えるものである。上記縦シール部は、従来、充填包装体に備えられる筒状の包装フィルムに備えられる長手方向に延びる縦シール部と同様の趣旨で備えられるものである。即ち、帯状の包装フィルムを長手方向に延びる両側縁部が重なるように筒状に巻いて筒状フィルムを形成し、次いで、該筒状フィルムの前記の両側縁部を、高周波誘電加熱、超音波加熱、レーザー加熱、抵抗加熱等による溶着、接着剤による接着（ヒートシールを含む。）等の常法に従って、長手方向（縦方向）に連続してシール（接着）することにより、筒状の包装フィルムが形成されるものである。縦シール部は、筒状の包装フィルムの長手方向の全長に亘って備えられ、これにより、筒状の包装フィルムに充填されて封入される内容物を密封状態に保存することができる。筒状の包装フィルムに備えられる長手方向に延びる縦シール部の幅は、適宜定めることができる。
[Vertical seal extending in the longitudinal direction]
The cylindrical packaging film provided in the filled package of the present invention has a vertical seal portion extending in the longitudinal direction. Conventionally, the vertical seal portion is provided with the same effect as the vertical seal portion extending in the longitudinal direction provided on the cylindrical packaging film provided on the filling package. That is, the strip of packaging film wound into a cylindrical shape as the side edge portions are overlapped to form a tubular film extending in the longitudinal direction, then the above side edge portions of the cylindrical film, the high-frequency induction electric heating, ultrasonic According to a conventional method such as welding by sonic heating, laser heating, resistance heating or the like, bonding with an adhesive (including heat sealing), etc., it is continuously (sealed) in the longitudinal direction (longitudinal direction) to form a cylindrical shape. A packaging film is formed. The vertical seal portion is provided over the entire length of the cylindrical packaging film in the longitudinal direction, and thereby, the contents filled and sealed in the cylindrical packaging film can be stored in a sealed state. The width of the longitudinal sealing portion provided in the cylindrical packaging film and extending in the longitudinal direction can be determined as appropriate.
縦シールする方法は、高周波誘電加熱、超音波加熱、レーザー加熱、抵抗加熱等による溶着、接着剤による接着（ヒートシールを含む。）等の常法を採用することができる。筒状の包装フィルムは、極性を有する樹脂であるポリ塩化ビニリデン系樹脂を含むことから、縦シールの効率性や、シール強度の調整の容易さ等の観点から、高周波誘電加熱による縦シールが好ましい。具体的には、筒状フィルムの長手方向に重なって延びる両側縁部を走行させながら、高周波誘電加熱装置のシール電極とアース電極との間を通過させる。この両電極の間に高周波電力を供給することにより、筒状フィルムの重なった両側縁部に高周波溶着による連続的な縦シール部が形成される。
How to longitudinal seals, high-frequency induction electric heating, ultrasonic heating, laser heating, welding using resistance heating or the like, (including heat sealing.) Adhesive bonding can be adopted a conventional method or the like. Packaging film of the tubular, since it includes a polyvinylidene chloride-based resin is a resin having a polar, efficiency and the longitudinal seal, in view of easiness of adjustment of the sealing strength, the vertical sealing by high frequency induction electric heating preferable. Specifically, while traveling side edge portions extending overlap in the longitudinal direction of the tubular film, passing between the sealing electrode and the ground electrode of the high-frequency induction electric heating device. By supplying high-frequency power between the two electrodes, a continuous vertical seal portion is formed on both overlapping side edges of the tubular film by high-frequency welding.
