New twist in candy wrap.
Film-grade polylactic acid (PLA) resins from Cargill Dow LLC, Minnetonka, Minn., are being used for the first time to make candy twist wrap. NatureWorks PLA grades 4032 and 4042 are part of the biodegradable resin family derived from bacterially fermented cornstarch. They are being used to make biaxially oriented films for JoEl Inc. in Elizabeth-town, Pa., a producer of organic candy. PLA produces a clear film with twist retention equal to that of cellophane. In addition, PLA has low heat-seal initiation temperature (180 F) and high seal strength (2 lb/in.). JoEl reports that PLA film works well in its high-speed (1300 pieces/min) wrapping and bagging equipment. Cargill Dow says PLA film also has potential in pillow packs, over-wrap, and non-twist (e.g., lollipop) wrap. Tel: (952) 742-0400, www.natureworkspla.com
