Abstract
A package having two or more compartments, adjacent compartments being seperated by a peel seal tape. A peel seal is formed by joining peel seal material coated on one surface of a substrate to one package wall, the other surface being coated with sealant material for hard sealing the substrate to the package wall. The substrate and coatings are formed by extrusion. The adjacent compartments of the package are filled with different materials. When one compartment is squeezed with sufficient pressure, that pressure breaks open the peel seal, allowing the respective contents of the two compartments to be mixed without removing the contents from the still externally sealed package.
