Plural compartment package

A plural compartment package (20') for housing and storing two different materials, such as, for example, an epoxy resin material (24') and a polyamine material (22'), which are to be mixed together so as to form an adhesive compound. First (26') and second (28') sheets of film material are secured together by means a peripheral heat-sealed region, and a third sheet (30') of film material is interposed between the first and second sheets of film material so as to form, together with the first and second sheets of film material, separated compartments (32', 34') within the package. The third sheet (30') of film material extends the entire length of the package, although it is preferably heat-sealed to the first sheet (26') of film material at a mid-point portion thereof, and in this manner, all peripheral heat-sealed regions (50') of the package (20') comprise three-layer laminates having the same thickness dimensions dimensional characteristics. The portion of the third sheet (30') of film material partially defining the second compartment (32') is provided with easily rupturable perforations (82'). A frangible cap (90') normally covers the perforations (82') so as to prevent premature leakage of the material.
