Just one roll of Fill-Air Flow Bags will produce a fill volume equivalent to more than three-and-a-half 14-cubic-foot bags of packing peanuts to save nearly 50 cubic feet of valuable space in crowded back rooms and fulfillment operations, as well as material savings in the amount of loose fill needed to have on hand. Two fill choices allow you to produce either 11 high-fill or 20 low-fill inflated plastic bags per minute. Its reusable design can be reinflated by blowing air over the valve opening for cost-efficient operation and increased sustainability. Flow bags are perfect for retail shipping service centers, retail stores, e-tailers, light industry, company mail rooms, printers, marketing agencies and more. Ready-to-fill, perforated bags are designed for use with the Sealed Air Fill-Air Flow Inflatable Packaging Machine (sold separately).
