Where Do Random Case Sealers Work Best?

Random case or carton sealers are ideal for production lines or facilities where cartons of different dimensions are processed in random order such as ecommerce fulfillment, 3rd-party logistics and food & beverage. Manufacturers also benefit from the ability to seal components and finished goods in different-sized cartons for shipment. Random case sealers come in semi-automatic models where an operator is required or fully automatic where no operator is required.
