The Zip#n Store pouch was co-developed by Pyramid Flexible Packaging and by Presto Products, maker of the polypropylene Fresh-Lock zipper for retort applications. The package is now being introduced in six varieties in the United States by Blue Star Food Products, Miami. Unlike tuna packers, Blue Star has developed its own pasteurizing process that uses lower temperatures and less time in the retort to create a much fresher-tasting product, says Steve Harmell, vp of marketing and sales for Blue Star.
