Plastic Suppliers Inc. in Columbus, Ohio, last spring began producing the first cast and tentered TDO shrink film made of corn-based PLA (polylactic acid) from NatureWorks LLC, Minnetonka, Minn. The tricky part of the development was limiting MD stretch, notes Plastic Suppliers, which has a patent pending on PLA shrink film. Its Earthfirst TDO shrink film is 50 to 60 microns thick and up to 100 in. wide. It is used commercially for tamper-evident sleeves and bands.
