Description
(1)搬送方向に沿った第一熱シールを施されて途中から筒状にされて搬送される熱溶着可能なフィルム内に筒状にされた位置から先の位置において流体を連続的に送り込みながらこのフィルムに対し搬送方向に交叉する向きの第二熱シールをこの搬送方向に間隔を開けて順次に施してこのフィルムから隣り合う第二熱シール間に流体を封入した包装袋体を連続的に生成する装置であって、
(2)この第二熱シールが、筒状にされたフィルムを間に挟んだ状態で他方の熱ロール体の突き当たり部に回転により所定の周期で突き当てられる突き当たり部を備えた一対の熱ロール体によって施されるようにしてあると共に、
(3)この一対の熱ロール体の一方の突き当たり部の表面が複数の微細なディンプルが施されていない平滑面とされており、
(4)かつ、この一対の熱ロール体の他方の突き当たり部の表面に複数の微細なディンプルが施されている。
フィルムFとしては、一面に熱溶着可能なシーラント層を備えたものが予定される。例えば、合成樹脂製のベースフィルムFの一面にシーラント層を備えさせたものなどが予定される。ベースフィルムFとシーラント層の間には、必要に応じて一層又は二層以上の中間層が備えさせられる。
被包装物となる流体としては、醤油、ラー油、ラーメンスープ、ドレッシング、保冷剤、リンス、シャンプーなどの通常の流体や粘性流体が予定される。
包装装置による包装としては、三方シール包装、四方シール包装、ピロータイプ包装などが予定される。
(1)前記フィルムFを筒形に成形させ、かつ、縦向きに搬送させながら、
(2)このフィルムFが筒形に成形された位置より先の位置において、充填管2を通じて流体を連続的に送り込み、
(3)そして、このフィルムFが筒形に成形された位置より先の位置において、このフィルムFに対しこのフィルムFの搬送方向xに交叉する向きの第二熱シールSbを所定のピッチ毎に施すようになっている。
(4)そしてこれにより、先順位で施された第二熱シールSbと次順位の第二熱シールSbとの間に前記流体を充填させた包装袋体Hを連続的に生成するようになっている。(いわゆる液中シール)
前記一対のシーラ体4、4の他方の突き当たり部4aの表面、つまり、前記一対の熱ロール体4’、4’の他方の隆起部4bの突き出し端面4cの全体に、複数の微細なディンプル4dが施されている。

製袋速度:80袋/分
ロール圧(フィルムの挟み付け圧):500kPa
ロール温度:摂氏170度
連続して生成された包装袋体Hの10袋分をサンプリングし、一袋毎に第二熱シールSbの内縁部の厚さを包装袋体Hの左右二カ所(A点とB点)においてマイクロメータを用いて測定し(図15、図16)、A点とB点の厚さの平均値を算出すると共に、さらに10袋全体での平均値を算出したところ、下記の結果が得られた。
F フィルム
Sa 第一熱シール
Sb 第二熱シール
H 包装袋体
4 シーラ体
4a 突き当たり部
4d ディンプル
