Ocean Spray firmly grasps handled PET

Ocean Spray Cranberries, Inc., broke new ground in mid-April by introducing a 1-gal, clear, heat-set polyethylene terephthalate bottle that incorporates a preformed polypropylene side handle.

The new package will replace the standard bail handle added to 1-gal containers for various cranberry juice cocktails and drinks sold by the Lakeville-Middleboro, MA, agricultural cooperative.

Ocean Spray believes the handled bottle's chief benefit is in consumer handling. "The bails are convenient for carrying," says Ray Bourque, director, product and packaging R&D. "But you don't have the pouring control that you have with this package." Bourque says the new pack does allow single-handed pouring even with a full container. However, some consumers may still find a full gallon too heavy to lift easily with one hand.

The bottle is supplied by Ocean Spray's long-time injection/stretch blow molding vendor Yoshino America (University Park, IL), which has multiple patents surrounding the technology.

What's unique is that the PET preform is actually blow-molded around the preformed PP handle. "It's quite a technical feat," says Bourque, "and working with Yoshino it's taken us years to perfect." He adds that Yoshino has also patented the handle design to ensure that it remains locked to the bottle during packaging, distribution and end-use, while separating easily for recyclers.

At Yoshino, on a modified injection/stretch blow-molding machine whose supplier the molder will not identify, the handles are unscrambled, oriented and positioned into the blow molding machine at the precise time that the mold halves close. Both Yoshino and Ocean Spray were reluctant to share manufacturing details.
