A box sealer is a machine used in packaging to securely close boxes or cartons. It applies adhesive tape or glue to the seams of the box, ensuring that the contents are protected during storage and transportation. Box sealers are commonly found in warehouses and manufacturing facilities, where they help streamline the packing process. There are different types of box sealers, including manual, semi-automatic, and fully automatic models. Each type varies in complexity and speed, catering to different production needs. Using a box sealer can improve efficiency and reduce labor costs in packaging operations, making it an essential tool in the logistics industry.
