Indianapolis-based Alcoa Closure Systems International thinks it has found the proper balance between leak-resistance and closure affordability with Seal-Max, a 38 mm screw on/screw off cap that recently debuted on Moomentum 14 oz. high density polyethylene (HDPE) milk containers from Marva Maid Dairy in Newport Beach, Va. The HDPE application requires a liner to compensate for the imperfections of HDPE bottles, but the standardized cap is more economical than the Extra Lock 38 mm cap Alcoa developed for Gatorade's hot-fill needs. Baraboo, Wis.-based Foremost Farms also is converting to the cap for its Grip It, Sip It single serves.
"For those processors who feel leak resistance and appearance are critical, this is a step up from the snap-on caps that account for 80 percent of the dairy closure market," suggests Alcoa's Larry Gibson. "We didn't want to have a Cadillac closure with a Yugo appearance."
