Abstract
Un rouleau de sacs en plastique à poignée est formé à partir d'un tube continu applati. Chaque sac est délimité par deux thermosoudures espacées longidutinalement et peut être séparé du rouleau le long de lignes perforées. Les poignées (32) et la bouche (30) du sac sont formées par découpage du tube à l'emporte-pièce. On obtient une meilleure séparation des couches de film par perforation d'une petite partie de bordure de la bouche du sac située centralement entre les grandes parties de bordure lisses intérieures opposées, et déchirure du film thermoplastique de chute de la bouche du sac découpée à l'emporte-pièce, afin de produire un bord brut présentant une série de parties discontinues de bordure de film déchirées facilitant la séparation de couches de film adjacentes bloquées pendant l'ouverture de la bouche du sac.
