What is the effect of aluminum foil bag for heat sealing strength? Some print down adhesion together, or ink layer separation adhering to print on the back of another layer, this is the adhesion, reason may be that only when dry ink layer surface false stem, and solvent residual, happened in the environment of high temperature and wet ink layer to dissolve. We want to solve this problem, one way is to add oleic acid amide and wax powder to anti aging; Another is to use a dedicated fast dry solvents to solvent to dilute ink, reduce the occurrence of false dry ink membrane; Either change the resin to improve the printing ink solvent release and dry.
