PERBAIKAN SIFAT ADHESI TINTA ORGANIK PADA PLASTIK BIODEGRADABLE DENGAN PERLAKUAN PERMUKAAN MENGGUNAKAN SINAR ULTRAVIOLET

Abstract

This research is about improving the adhesion properties of biodegradable plastics on organic inks which will then analyze the changes that occur in terms of physical, chemical, and wettability properties. The method used is a surface treatment method using ultraviolet light which is then subjected to surface characterization. This is a change in physical properties, chemical properties, and wettability properties that affect the adhesion properties of biodegradable plastics. As well as the optimal duration of surface treatment using ultraviolet light is 90 minutes. The adhesion properties of biodegradable plastics increase after surface treatment with ultraviolet light. this indicates the success of improving the adhesion properties of biodegradable plastic surfaces.
