A Study of Polybutylene adipate terephthalate Printability with Flexography ink

Today the economic consumption of biodegradable polymers is of capital importance in many applications. One of the most commonly used biopolymers is Polybutylene adipate terephthalate (PBAT). The printability of biodegradable film has not been fully investigated. This work tested the printability of modified BAT(CE-PBAT) films and compared the print qualities to common packaging films like corona-treated low-density polyethylene (LDPE). Solvent-based flexo ink was applied to test the printability of films. Some properties of printing inks and films were tried out and demonstrated. Likewise, the contact angle of films was studied. The densitometry of printed samples was evaluated. Ink adhesion to the substrate as other essential parameters that influence the quality of printed samples was also examined. It has been found that the CE-PBAT, can be successfully printed with flexographic solvent inks and could achieve similar quality compared to common packaging films.
