Abstract
Abstract A multiple-compartment package wherein a suitable web or webs having barrier properties for active chemicals is utilized to form a pouch-like multiple-compartment container. The container has the compartments thereof separated by rupturable barrier seals. However, the seals between adjacent compartments do not have the barrier properties of the webs per se from which the package is formed. In order to restrict mixing of migrating chemicals, one or more empty compartments are disposed between those compartments containing the products which are to be mixed.
