Apple-shaped bottles get plastic version
Watsonville, CA-based apple juice processing company S. Martinelli & Co. has partnered with Graham Packaging Co. L.P. (www.grahampackaging.com) to launch a PET plastic version of its 10-oz apple-shaped glass juice bottle.
Plastic closures are supplied by O-I (www.o-i.com).
Martinelli wanted a hot-fillable panel-less label-free container with barrier properties. The challenge for plastic container supplier Graham was to maintain the shape of the bottle when the hot-filled juice cooled inside the container. The challenge was met by using liquid-nitrogen dosing into the filled container head space.
The liquid nitrogen converts to a gaseous state inside the bottles and serves to resist bottle deformation by exerting pressure against the internal container sidewalls. Liquid-nitrogen injection also extends shelf life by flushing out oxygen. The equipment for this process is manufactured by Cryotech International/ VBS (www.cryotechinternational.com).
Introduced in December 2005/January 2006 the new PET bottles are making their way from West Coast markets to distribution areas in the Midwest and East Coast. S. John Martinelli VP and GM of Martinelli’s says “The clear apple-shaped bottle tells the consumer that this is a 100-percent natural product. The package visually reinforces the fact that Martinelli’s award-winning apple juices are made from fresh apples only with no additives of any kind.”
