Similar to the pull-open feature on baby and home care wipes, Kraft’s Chips Ahoy! packages offer a ‘Snack ’n Seal’ resealable top that’s unique among cookie products. The package won a Gold Award in this year’s DuPont competition.

“Snack ’n Seal is a patented product packaging system that, through the use of technology and consumer insights, delivers a true innovation to the marketplace,” says Laurie Guzzinati, senior manager, corporate and government affairs at Kraft’s facility in East Hanover, NJ.

The Snack ’n Seal package allows consumers to open and reseal the cookie pack from its top panel, rather than from the end of the pack, which is more traditional. The film consists of .7-mil metallized oriented polypropylene that gets extrusion-laminated to an extrusion lamination of 48-ga polyester and 14# white opaque low-density polyethylene. Graphics are delivered via eight-color reverse-gravure printing on the 48-ga polyester.

Kraft refers to the resealable top as a label. It consists of a 2-mil OPP facestock with a Food and Drug Administration-approved adhesive for direct food contact. According to Kraft, “labels are created by rotary die-cut, partially deadened (to create a tab) and then printed with two colors to indicate ‘lift here.’ The labels are then applied to the printed rollstock, and precision die-cut from underneath.”
