Abstract
Container or bags for sealing food or other objects are made from a composite material. The material has an outer oxygen-impermeable layer and an inner heat-sealable layer. The two layers are joined by an intermediate adhesive layer that is stiffer than either the inner or outer layer. Other embodiments may be made of a single layer of heat-sealable material that resists the flow or air or oxygen inside the container. Channels on the sides of the container or bag form an interconnecting network and allow a flow of air and oxygen for evacuation of the bag. The material may be laminated in a continuous fashion as a tube wherein bags are made by cutting and sealing the material at desired intervals.
