摘要: Abstract Effect of surface printing on the biodegradability plastic films was studied. Biodegradable (polybutylene-succinate (PBS)) printed with four kinds gravure inks were placed in soil for 1 year. The consisted carbon black-pigment resins: poly-(e-caprolactone) (PCL), nitrocellulose-polyamide blended resin (NT), polyvinyl chloride-vinyl acetate copolymer (V), and nitrocellulose (NC). Degradation film specimens one side both sides as well control without monitored every 3 months by collecting sample measurement weight loss. No appreciable degradation observed until 6 after placement 9 specimens. And PCL- NC-printed one-side V-printed both-side significantly slower than that 9-month at p...
