In fall 2003, Hilex Poly re-entered the plastic bag and film products business with the purchase of the high-density film products division of Sonoco. Now, just one of the company's bag machines can produce over three times as many bags as the entire original plant's initial capability. Focusing primarily on high-density polyethylene film products and related services, Hilex Poly products range from bagging systems to agricultural films. The company's patented QuikMate EZ-open feature is a standard for self-opening plastic bags. Other key innovations and patents include specialized bag features and dispensing hardware. Hilex Poly is a United States-based company with headquarters in Hartsville, S.C., and six domestic manufacturing facilities located across the country, including Farmers Branch, Texas.
