Bag-in-box system for use in dispensing a pumpable product |
| 摘要 |
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. |

1. A bag-in-box system for use in dispensing a pumpable product comprising:
a) a carton; b) a flexible thermoplastic pouch disposed in the carton; c) a spout joined to the pouch; d) a spout closure, and e) a pumpable product disposed in the pouch;wherein the flexible thermoplastic pouch comprises
i) an outer wall comprising a coextruded film comprising
(a) an outer heat-sealable layer comprising an ethylene polymer or copolymer;(b) a first tie layer disposed between the heat-sealable layer and a first intermediate layer, the tie layer comprising a chemically modified polyolefinic adhesive;(c) a first intermediate layer comprising a polyamide;(d) a core layer bonded to said first intermediate layer comprising a chemically modified polyolefinic adhesive;(e) a second intermediate layer bonded to said core layer, and comprising a polyamide; and(f) a second tie layer bonded to the second intermediate layer comprising a self-weldable chemically modified polyolefinic adhesive; wherein the film is a collapsed lay-flat tubular film; and ii) a discrete inner wall comprising ethylene polymer or copolymer;the outer wall sealed to the discrete inner wall at the perimeter of the pouch. |
