Sliding Zipper Bags deliver both convenience and durability. Our 3SZ1618 bag measures 16" x 18" and work great for packaging clothing, textiles, kits, and more. Secures and holds items like dress shirts, T-shirts, and fabric in place. These bags also provide a great solution for kits or multi-piece products. Made from 3 mil polyethylene material, these bags are an affordable packaging option when crystal clear clarity is not as important. A white tab sliding mechanism provides an airtight closure and allows easy access to your product. Food safe and acid-free.
