Abstract
A bag-in-box system for use in dispensing a pumpable product includes a carton, a flexible thermoplastic pouch disposed in the carton, a spout joined to the pouch, a spout closure, and a pumpable product disposed in the pouch, the flexible thermoplastic pouch including an outer wall including a coextruded film having a polyethylene layer, a tie layer, and a polyamide layer, and a discrete inner wall including an ethylene polymer or copolymer, or a composition like that of the outer wall, the outer wall sealed to the inner wall at the perimeter of the pouch. Optionally, a discrete intermediate wall can be disposed between the outer wall and inner discrete wall of the pouch. The system can further include a pump operatively connected to the pouch and carton to dispense the pumpable product from the pouch.
