About Sigma Stretch film manufacturing.... © Sigma Stretch Film 2016 Sigma Stretch Film® began producing film in 1993 with the intention of becoming the easiest company to do business with in the industrial packaging market segment.  Since those humble beginnings, with one small factory in Lyndhurst, N.J., Sigma has grown to become the largest industrial stretch film producer in the world.  Over this time the company has added four manufacturing sites in Kentucky, Oklahoma, California and Canada in order to be geographically located to support our distribution partners and clients. Every production site is guided by the same standards of production, formulations and quality control to ensure consistent, top of class quality products throughout North America.  Each facility has its own Customer Care Representatives to quickly and accurately respond to the needs of all stakeholders.
