Title
(EN) BAG WITH REINFORCING FEATURES
(FR) SAC À ÉLÉMENTS DE RENFORT
Abstract
(EN)
A plastic bag with flexible sidewalls defining an interior volume for holding contents includes a reinforcing feature to resist puncture and/or rupture of the bag. The reinforcing feature may include reinforcing the portion of the bag proximate the bottom edge with additional or thicker thermoplastic material. In various embodiments, the reinforcing feature may be a multi-layer strip of plastic material attached along a bottom edge of the bag, either internally or externally, to provide additional material resistant to puncture. The reinforcing feature may be adhesively bonded, heat bonded, or cold bonded to the bag sidewalls. In other embodiments, the sheet material used to produce the bag may be made with varying thicknesses. In addition, methods of manufacturing a bag with such reinforcing features in a high speed automated process are disclosed.
(FR)
L'invention porte sur un sac en matière plastique présentant des parois latérales souples définissant un volume intérieur pour contenir des contenus, lequel sac comprend un élément de renfort pour résister à un perçage et/ou à une rupture du sac. L'élément de renfort peut comprendre le renforcement de la partie du sac à proximité du bord inférieur avec une matière thermoplastique additionnelle ou plus épaisse. Dans différents modes de réalisation, l'élément de renfort peut être une bande multicouche de matière plastique attachée le long d'un bord inférieur du sac, soit intérieurement soit extérieurement, de façon à produire un matériau additionnel résistant au perçage. L'élément de renfort peut être lié par adhérence, lié à la chaleur, ou lié à froid aux parois latérales du sac. Dans d'autres modes de réalisation, le matériau en feuille utilisé pour produire le sac peut être réalisé avec différentes épaisseurs. L'invention porte également sur des procédés de fabrication d'un sac avec de tels éléments de renfort dans un procédé automatique à grande vitesse.
