Abstract: A collapsible dispensing container for packaging preparations containing hard-to-hold ingredients such as acetic acid. The container comprises a deformable tubular body and a thermoplastic head fused thereto. The wall of the tubular body is made of a plurality of laminations, including a sealant core film which prevents product migration and delamination. The wall of the tubular body comprises, from the inside of the tubular body toward the outside thereof, overlying layers of ethylene-acrylic acid copolymer, the sealant core film and an outer thermoplastic (e.g., polyethylene) layer bonded to the outer layer of the sealant core film by another layer of ethylene-acrylic acid copolymer. The sealant core film comprises a metallic foil (e.g.
