Plastic packaging box glue bonding process
PP materials due to good acid and alkali resistance effect, the application scope is increasingly wide, such as: disposable cups, crisper, plastic packaging boxes, PP electromagnetic boxes, drinking cups, etc.
PP is a material with insensitive surface and relatively large inertia. The adhesive effect of plastic packaging box can only be achieved by using PP primer together.
Sl-320ab is recommended for normal temperature curing, high speed, high bonding strength, strength can lead to material damage, aging resistance, no whitening, no trace of glue after viscidity, suitable for small area bonding.
Glue bonding process for plastic packaging boxes:
1. Surface treatment: the PP surface that needs to be bonded is first treated with agent A.
2. Gelatinize: After half a minute or one minute volatilization, apply agent B to any surface of the adhesive for bonding. The whole process is 1-minute internal curing.
3. Curing: It can dry within one minute at room temperature and completely dry within 24 hours, achieving very good results.
