ABSTRACT:
A dual compartment package for containing reactive substances in separate compartments which is suitable for being produced continuously from a single web of film material, and a method for making same. The web of film is formed into a tubular member having a first compartment which assures a generally circular cross section when filled, and a second compartment formed inside the first compartment. The second compartment is attached to the sidewall of the first compartment such that a single sealing formation through three plies of the film material closes both compartments longitudinally. The method provides for a simplified formation of a series of said packages wherein only a single seal forming apparatus is utilized.
