Abstract
A multi-compartment flexible package is provided for filling with products which are to be stored separately from each other. A multi-compartment package made from flexible thermoplastic material heat sealed at the peripheral edges is provided. The compartments are formed by rupturable partition strips heat sealed in place between the sheets of thermoplastic material forming the package. The partition strips are comprised of at least one layer of heat sealable material which is different from the thermoplastic material and which can be ruptured under pressure allowing the products in the compartments to mix.
