Due to the high glue density and smooth surface of some cartons, it is easy for the transparent sealing tape to be difficult to adhere to, so that when the goods are loaded into the box, the sealing tape is prone to popping off or not being firmly adhered. As a result, effective sealing cannot be performed. Usually for the cardboard used as sealing paper, we should conduct a tape adhesion test. The specific method is: take a transparent tape with moderate viscosity, stick it on the cardboard paper, and then tear the tape to separate it from the cardboard paper. If you can tear off the surface layer of the cardboard paper together, It is enough to show that this sealing tape is suitable for sealing the carton. If it can be separated easily and the surface of the cardboard is not damaged after tearing, it means that the cardboard is not suitable for tape sealing.
