1. The packing box degummed in the cold winter. Mainly because some glue low temperature resistance performance is not good, under 5℃ glue surface loss of activity resulting in adhesive decline or disappearance.

2, in the hot summer glued packaging box in the warehouse or transport car popping degumming. The main reason is that the high temperature resistance of the glue is not good. At the temperature of 50-60 ℃, the glue layer becomes soft and the strength becomes small, which leads to the degumming of the packaging box.

3. The adhesive effect of the packaging box is very good at the initial stage of adhesive (within half a month), and the deadhesive phenomenon of the packaging box appears with the extension of time. It is mainly because of the poor bonding durability of the glue itself, most of the glue is added with some plasticizer, with the extension of time, the plasticizer migrates to the paper base, resulting in the rubber layer hardening, brittle and degumming products. On the other hand, it is because the glue contains a large number of unsaturated bonds, resulting in poor aging resistance of the product.

4, the warehouse is very wet for a long time stored in which not only the humidity of the product exceeds the standard and the product degumming. The main reason is that the product absorbs water, and the water resistance of the glue itself is not good, which leads to the soft layer and delamination. And we produce a series of sealing glue because of a certain water resistance, so the overflow glue should be wiped with solvent, and the container cleaning to water and solvent is this reason.
