Abstract
A thermoplastic flexible package includes a first non-shrinkable panel, an opposing second non-shrinkable panel, a first shrinkable panel and an opposing a second shrinkable panel. The panels are connected longitudinally with panel seals. The first non-shrinkable panel and the second non-shrinkable panel each forms a gusset. A first seal connects the first shrinkable panel and the second shrinkable panel in the transverse direction at or near the upper edges. A second seal that opposes the first seal connects the first and second non-shrinkable panels and the first and shrinkable panels in the transverse direction at or near the lower edges.
