Application of para rubber latex mixed with organic dyes as printing ink for biodegradable plastic film
Abstractcontent of 35.9% and 41.2%, which had the viscosity of 9.52 seconds and drying time of around 5 minutes. The viscosity of Para rubber latex with solid content of 59.0% and 61.4% was very high; thus, resulted in coagulation. Then modified rubber latex CNR with solid content of 16.5%, 19.2%, 26.8% and 28.2%, which had the viscosity around 8.30 seconds and drying time of around 5 minutes. Dye solution was prepared by adding 1 part of dye to 1 part of water (w/w). The formulation of ink that yielded the highest optical density of 1.43 was 8.4 g dye solution in 84 g Para rubber latex. The additive substances were added to the mixture to make up the weight of 100 g. The result showed that printing ink made from natural Para rubber latex with solid content of 35.9% and 41.2% and modified rubber latex CNR with solid content of 16.5%, 19.2%, 26.8% and 28.2% can be printed on the biodegradable film without surface treatment and ink layer color was brilliant. The modified rubber latex with solid content of 16.5%, 19.2%, 26.8% and 28.2% showed better print quality and smoother ink layer than the natural Para rubber latex. However, the adhesion resistance and rub resistance of this ink were inferior to traditional ink using acrylic binder.
