The drawings and description disclose a heat sealable container for edible oils and other types of oils, and a blank for constructing same, having a laminated wall construction of suitable oil resistant barriers or layers which are compatible with one another insofar as bonding and sealing are concerned. Such wall construction includes central layers of aluminum foil and fluorochemically treated paperboard secured to one another by a suitable adhesive, an ionomer layer, such as Surlyn, formed on each outer paperboard and foil surface, and a layer of thermoplastic material, such as polyethylene, formed on each outer Surlyn surface.
