子フィルムウェブ及び各包装の長軸に対して横向きの底ガゼットを各包装に設けることによって達成される。任意の高さを有する底ガゼット包装が容易かつ効率的に形成され得る。
サイドシーリング面間に延在する横方向シーリング面とを含む。
ング面のサイドシーリング面は、対応する横方向シーリング面から上方に、GHにTLDの2倍を足した値以上の長さ伸びる。
沿って形成された折りたたみ部と反対側の包装の側辺に示されているが、可撓性ウェブは他の方法で、例えば、図2において破線で示される背面包装パネル16に設けられた長さ方向継ぎ目18’に沿って自身に接合されてもよい。
サイドシール22は、包装10の底ガゼット20の対応する端部と重なる。
ドシーリング面52はGSSより大きい横方向寸法を有する。各スリーブ44が、ガゼット20を形成するために幅GWの横方向寸法を有する場合、各シーリング顎体50のサイドシーリング面52間の間隔は、GWからGSSの2倍を差し引いた値以下である。
に調節可能であるよう構成されてもよい。かかる構成は、図13に示されている。図13では、各シーリング顎体50は、包装/ガゼット幅及びガゼット高さを調節するための横方向に調節可能なサイドシーリング面152を含む。
サイドシール22を形成するよう構成される。これにより、包装のこの領域を好適に堅固に強化し、さらに包装にポーチ状の内部空間を与えることができる。
修正及び変更がなされ得ることが理解されよう。本明細書で説明される具体的実施形態は、いかなる限定も意図又は示唆するものではない。本開示は、添付の特許請求の範囲によって、請求項の範囲に含まれるかかる変更を全て包含するものである。
