包材のヒートシール装置に関する。
（従来技術） 熱可塑性樹脂フィルム単体、或いはフィルム、紙などと
熱可塑性樹脂層の複合体からなる包材の熱接合方法とし
て、ヒートシール法は最もよく利用されている。
一般に電熱、高温蒸気などを熱源とした加熱板をヒート
シール部に接触加圧し、熱可塑性樹脂層を加熱溶融の上
、圧着せしめ、その後加圧を解除し、自然冷却して凝固
させる。場合によっては強制冷却することもある。
ここで十分な冷却前に外力が加わるとシール不良が起る
ことがある。かような外力として次のケースをあげるこ
とが出来る。
（１）　ビロータイプの包装の場合、横方向にヒートシ
ールし底を形成した直後、充填する。
被包装物の荷重がヒートシール部を押し開く方向に作用
する。
（２）容器の場合、充填し蓋板をヒートシールするが、
次工程に送られる途中ヒートシール部にコンベアその他
の機械的振動が伝わってシール面が局部的にはがれる。
（３）　ホット充填容器の場合、内部にとじ込められた
空気が高温液体（被包装物）により加熱され膨張し、蓋
板に内圧として働く。
その他包装物の移動中、各種外力が加わるケースがある
。いずれも樹脂のホットタック性によりシール不良から
まぬがれるように管理されるのであるが、樹脂の選定、
加熱温度、加圧解除の時機、ヒートシール部の樹脂量、
及び上記の各種外力に対する配慮などの制約を受ける。
又従来のヒートシール法では上記の如（ヒートシールの
信頼性に今−歩欠けるところがあり、例えばホット充填
などのように長期間保存を商品価値とする商品にとって
は、ヒートシール不良は重欠点ともなる。
