Abstract
A low cost barrier package that can be manufactured on presently available equipment having a formed-in-place, controlled release coating integral with the inner surface of the package and substantially free from air entrapment. Total evacuation of the product to be dispensed is effected by controlled deformation of the barrier formed. Permeability is controlled and high speed, high pressure filling processes can be used.
