ABSTRACT:
A multiwall gussetted bag of the type having pinch bottom and pinch top closures is provided with a seamless plastic liner. The liner is gussetted and one-half of each of the gussets of the liner nests inside of the corresponding gusset half of the remaining bag layers, while the other half of each of the gussets extends inwardly toward the middle of the bag and does not nest with the corresponding gusset half of the remainder of the bag. This condition is present while the bag is empty. When the bag is filled, the non-nesting liner gusset halves are expanded by internal pressure resulting from filling the bag with the product into nesting relationship with the corresponding gusset halves on the remainder of the bag.
