Introducing Hefty Press to Close Freezer Bags, our first-ever press to close design for portioning foods for freezer storage or marinating cuts of chicken or beef! The stand-and-fill expandable bottom makes it easy to load food, craft supplies, or other household items into these freezer bags. The easy grip, double zipper closure creates a secure seal that snaps closed with just a press. These bags are microwave safe for even more convenience, so you can go straight from meal prep to meal time. When you’re done, you can recycle Hefty brand food bags when clean and dry at participating retailers in the United States. And don’t forget: all Hefty products come with a 100% satisfaction guarantee.
