Methods for preparing oriented polymer tubes, such as biodegradable polymer tubes suitable for in vivo use, are provided herein. The disclosed methods provide alternatives to the typical extrusion/expansion methods by which oriented polymeric tubes for such uses are commonly produced. Advantageously, the disclosed methods can provide more homogeneous molecular orientation of crystallizable polymers within the tube walls, which can endow such polymeric tubes with enhanced strength (e.g., resistance to compression) and toughness.

Polymeric tubes with controlled orientation

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.
