Based in Sparta WI Century Foods is a contract packager of powdered protein beverages in HDPE jars sold at retail in a variety of sizes up to 5-lb. Before the induction sealers were installed the firm’s tamper-evident feature consisted of pressure-sensitive foam liners pressed down onto containers during capping. But powder residue on the land of the container occasionally jeopardized seal integrity of these liners.
Since the Pillar Foiler induction cap sealers were installed tamper evidence is assured. Foil liners are already inside the injection-molded polypropylene caps that are bought by Century Foods from several suppliers. Shortly after caps are applied and torqued down—at speeds to 60 jars/min—the containers run through the 4-kW Pillar machines so that the foil can be induction-sealed to the neck finishes of the containers.
According to Century’s Rick Halvorsen national director of sales it’s largely about putting customers at ease. “When consumers open these jars and see that inner seal intact they can have full confidence in the quality and integrity of the product” says Halvorsen. He acknowledges that induction sealing did add to the overall cost of the package. But the upcharge is far outweighed he adds by the benefit gained. (PR)
