Pet-product provider Hartz® Mountain Corp. has groomed its 2- and 5-lb bags of Bonanza™, Vita-Vittles® and Classic™ petfoods to ensure product freshness and convenience. Working with Zip-Pak® (www.zippak) and Hayssen Packaging Technologies (www.hayssen.com), Hartz has introduced what Zip-Pak says is the first commercial quad-seal pouch to feature slider-zipper technology.

Produced with Hayssen's new Ultima SV vf/f/s machine, the pouch features a transverse direction (TD) Slider™ zipper from Zip-Pak. Because it is applied at the top, rather than on the side or front panel of the flat-bottomed, quad-seal package in the transverse, or cross-web direction, the TD Slider makes it possible to incorporate slider zippers on standup packaging, Zip-Pak explains. The enhanced platform for graphics and marketing messages also helps increase shelf impact, the co. adds.
