Product Description: Ideal to use for packing cookies, sandwiches, nuts, potato chips and other oily stuff, the IYC Sandwich Bags are made with grease-resistant paper. Made with unbleached and chlorine-free paper, these bags are safe to use. With the greaseproof paper, this bag acts a natural barrier to prevent oil and grease from penetrating. They are uncoated and no petroleum-based paraffin wax is used to them. Also, this bag keeps the bread soft for up to 6 hours.
