Flat Heat Seal Bags meet FDA specifications for direct food contact. Usable space on the bag is less due to the flow seal (crimp) at the bottom. The bags can be sealed closed at the top with a crimp sealer, a poly heat sealer, or by attaching a header card.
Metallized Zipper Pouch Bags have improved barrier properties. Ideal for non-refrigerated items, these bags have a durable zipper, are heat sealable and available in 5 different colors.
