Plastics Color Corp. has begun marketing a blue tint masterbatch for polylactic acid applications.
The Calumet City, Ill., company originally developed the product for NatureWorks LLC, a Blair, Neb., producer of Ingeo PLA resins. Plastic Color Corp. now markets SoluPLAs TN920259 directly as a new grade within its SoluPLAs line.
The blue tint is one of a range of PLA enhancements offered by Plastic Color Corp. that extend the biopolymer's uses through options for control and adjustment of PLA clarity, UV resistance and noise reduction.
Other sustainable polymers made by Plastics Color Corp. include SoluPET colorants and other resins made partially from post-consumer regrind, and the SoluPur series of biodegradable polymers.
