Abstract

A recloseable multibag freezer bag including an inner liner bag and an outer support bag. The inner liner bag is a thermoplastic with a thickness of less than 2 mil and a specified secant modulus, has a mouth through which the interior of the inner liner bag is accessible, and is joined by a mouth seal to the throat of the support bag along the entire length of the mouth of the liner bag substantially enclosing an air space between facing walls of the inner liner bag and outer support bag. The outer support bag is a thermoplastic, and has a mouth and a throat. A recloseable mouth seal is affixed to its mouth to provide recloseable access to the interior of the liner bag through the outer bag while maintaining the enclosed air space between the inner and outer bags.
