Poly bags, sealers, and dispensers help protect and organize products for shipping or storage. Bags are used to transport and store hardware, clothing, and food. Open-ended poly bags are open on one end for filling but can be closed with a heat seal, staple, or tape. Poly bag and tubing sealers use pressure and heat to provide an airtight seal. Poly bag dispensers help organize bags and are used in restaurants and grocery stores.
