The use of adhesive tape for sealing is currently the most widely used method for sealing boxes. Fold the sealed folding sheet or the cardboard box that has already been sealed with adhesive, use a reel type pressure-sensitive tape to stick it across the folding seam of the sealing folding sheet, and apply a certain amount of pressure to seal the box tightly. The bonding length between each end of the cardboard box and the adhesive tape should generally be greater than 50 millimeters.

Sealing and packaging machinery refers to the machinery that seals the container after placing the product inside it. Container sealing can effectively protect products, prevent damage and deterioration during the shelf life due to packaging operations, and is also beneficial for the storage, transportation, and sales of packaged products. The quality of packaging largely depends on the sealing quality, and selecting a suitable sealing machine to achieve mechanical and automated operation of the sealing process is an important guarantee for improving the sealing quality.
