Packaging and shipping supplies store, identify, and protect goods during shipment. Boxes, mailers, and bags protect items and keep them organized during storage or transit. Protective packaging materials prevent damage to package contents during transit. Packaging tape, tape dispensers, case sealer machines, and carton staplers seal boxes and other containers for shipping. Strapping, stretch wrap, and heat-activated shrink wrap bind items together and protect them from dust or contaminants. Package marking and identification products label packages, containers, and other items with information about contents or handling.
