News | April 24, 2019 | By:

Raven Industries announced that its Engineered Films division has completed the installation and qualification of an advanced seven-layer barrier extrusion line, referred to as Line 15. This new production line is located in Raven’s state-of-the-art manufacturing facility in Sioux Falls, S.D.

Raven Engineered Films partnered with multiple industry equipment experts and worked extensively over the past year to design and install the new line. With advanced capabilities, the line was specifically designed to produce complex barrier structures for secure liquid containment and for the prevention of intrusive odors, gases and hazardous volatile organic compounds (VOCs). Raven is currently the leading manufacturer of barrier technology geomembranes used in the geosynthetics industry and produces seamless barrier containment films for the industrial packaging sector.

The new multi-layer barrier line produces blown film and sheeting up to 28 feet in circumference, with a thickness range of 4 mil to 80 mils and with optional surface texturing. It houses an impressive 66-inch diameter, seven-layer die that was engineered to provide maximum versatility, utilizing individual extruders for production of barrier structures. With expanded gauge definition, the new line produces both light and heavy gauge wide-width film and sheeting. In addition, its enhanced auto-wind capabilities allow for optimal output of folded sheeting up to 14 feet wide and single-wound sheeting up to 23 feet wide.

“Our new multi-layer line will directly increase available capacity for barrier film, tubing and sheeting while utilizing the latest equipment advancements for strategic growth in complex barrier designs,” stated Anthony Schmidt, vice president and general manager of Raven Engineered Films.
