发明名称 FLEXIBLE BAG CONSTRUCTION
摘要 <p>A paper bag is described comprising a pair of face panels consisting of front and back panels if different sizes. The front panel is narrower in width than the back panel. These panels are connected by gussets that include central gusset folds positioned in close proximity to one another when the bag is collapsed thereby dividing the bag into front, and rear tubes Vertically spaced apart transversely extending seals arc provided between the gussets and at least the front panel to securely hold a product in place between them. Diagonal seals are provided at the bottom of the bag, to seal portions of the gussets to adjacent parts of the front, and rear panels.</p>
