Freezer bags feature Grip n’ Seal technology. Triple system seal features an extended tab, easy-grip texture and double zipper. The extended tab and easy-grip seal make it easier to open and close the bag while the airtight zipper ensures that each plastic freezer bag blocks out air, providing unbeatable protection from freezer burn. That means less wasted food and more money saved. Stand Up Stay Open technology with a patented stand-up bottom and fold-over top makes filling a breeze.
