Printing control operation before composite biodegradable drug packaging film: 
When printing solvent-free composite biodegradable drug packaging films, the amount of ink and curing agent used should be appropriate, and the ink manufacturer will provide a reference ratio when providing ink. 
Before the production and use of biodegradable drug packaging films, a small trial should be conducted. If the amount of curing agent is too small, the degree of crosslinking between the curing agent and the resin will be low, and the adhesion strength, heat resistance, and hydrolysis resistance of the ink layer will be reduced. 
If there are too many curing agents for biodegradable drug packaging films, excessive cross-linking will occur, affecting the crystallization and microscopic phase separation between polymers, increasing the cohesion of the adhesive layer, causing excessive shrinkage of the ink layer, and causing delamination.
