CH-31806 Water based blister packing varnish
Rougher paper should be getting better adhesion than smooth paper .
This material is also one branch of overprinting varnish. For practice, The varnish oil had coated on the printed paper and storage waiting for packing products. The desired product will put on the coated paper and cover with certain plastic shell for mounting by heating pressure machine to get the blister sealing package .. Evaluation of its merits is the sealing speed, the broken state when the plastic shell was pulled out. The gloss property also be the point. Different mounting plastic shell , (PET, PVC) had to be suitable using this same blister oil. Generally speaking, water base blister oil had longer time for mounting processing than that of solvent based blister oil at the beginning. But after that, they are all the same mounting situation whatever solvent or water borne base oil.
Suggest processing :
(1) Instant heating temperature in200~300℃
(2)Heating time in 1.5sec~2.5sec，cooling time in 2sec
(3)Pressure 4-6kg/m 。
(4)Generally the temperature will not show，we will use electric current to
adjust。Generally in principle the PVC film will not scorch，the PET film will not Whitening。
