Cargill Dow: Degradable resin finds use in packaging films
NatureWorks PLA, a degradable starch-based polymer made by Cargill Dow LLC, is being used commercially in a packaging film application for the first time. The proprietary polylactide polymer is being used as the exterior film wrapping on golf ball sleeves sold in Japan by Dunlop Japan Ltd. The biodegradable film is manufactured by Mitsubishi Plastics. The film’s performance is said to be equal to or better than that of traditional packaging materials. In addition, it shows high clarity, high gloss, uv stability, and good dead- fold properties. Furthermore, the product is fully degradable in a municipal compost. Nature Works PLA is made from the lactic acid fermented from corn starch.
