Abstract
This is a method for assembling a dual inner flexible insulated pouch. A flat sheet of heat-sealable film is folded in such a manner as to form a dual inner pouch with two pocket openings at a bottom side and a pouch opening at a top side. The film is sealed by heat to form a permanent dual inner pouch structure containing two pockets each having an opening at the bottom side. One panel of flexible insulation material is inserted into each of the openings of the two pockets of the dual inner pouch at the bottom side. The bottom side of the pouch is placed into a bag formed of film so that the open ends of the pockets at the bottom side of the pouch are at a bottom closed end of the bag formed of film. The bag formed of film is heated so that it is sealed to the dual inner pouch.
