Abstract
Trash bags may be formed to include first and second sidewalls joined along a first side edge, an opposite second side edge, and a closed bottom edge to form an outer bag. A second inner bag may be inserted within the first bag to form a “bag-in-a-bag” type configuration in which the inner bag is bonded to the outer bag along side seals. When the outer and inner bags are formed primarily from LLDPE thermoplastic resin using a blown film process, the inventors have surprisingly found that such configurations provide increased and unexpected strength properties while using less material.
