In the process of adhering packaging products such as gift boxes, the following problems are always prone to occur: too much glue will cause glue to overflow after lamination, which not only affects the beauty of the product, but also easily occurs between the packaging boxes.

If there is no compression or the pressure is too small, the bonded product will automatically spring open. This situation is mainly for products with high stiffness, so it must be pressed for at least half an hour, because many adhesives are contact adhesives. Therefore, the two adhered surfaces must be effectively pressed together. In a unit time, if the initial tack force is less than the product elasticity, the product will spring open, so the average product requires a 0.5 hour squeeze time.

The paper packing box will appear degummed in the cold winter season. This is mainly due to the low temperature resistance of some adhesives. Below 5 ° C, the surface of the adhesive will lose its activity, causing the adhesive force to decrease or disappear. And in the hot summer, the sticky packaging box will also come out in the warehouse or the transport car, and it will pop open and debond. This is mainly because the high temperature resistance of this kind of adhesive is not good. At a temperature of 50 ° C to 60 ° C, the adhesive layer softens and the strength becomes small, which results in degumming of the packaging box.
