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 weakene d areas and takes up the forces applied to them when the bag is loaded.</SDOAB > |
