A plastic T-shirt bag comprises an extruded plastic tubular form having side gussets and a seal line (14) at the bottom of the bag. The junctions (24) of the inner folds of the gussets and the seal line (14) are the weakest areas of the bottom of the bag. A reinforcement tape (30) extends across both weakened areas and takes up the forces applied to them when the bag is loaded.
L'invention concerne un sac plastique comprenant une structure tubulaire en plastique extrudé et comportant des soufflets latéraux ainsi qu'une ligne (14) de joint d'étanchéité située sur la partie inférieure de ce sac. Les jonctions (24) des pliures internes des soufflets et de la ligne (14) de joint d'étanchéité sont les zones les plus fragiles de la partie inférieure de ce sac. Une bande (30) de renforcement recouvre ces zones fragilisées et absorbe les forces qui y sont appliquées lorsque le sac est chargé.
