SIOUX FALLS, S.D. (Dec. 27, 10:55 a.m. ET) — Raven Industries Inc. has installed a seven-layer blown sheet line to its Technology Solutions Center. The company claims the system is the world's largest for making seven-layer barrier sheeting.
Sioux Falls-based Raven worked with equipment supplier Davis Standard LLC to plan, design and develop the line, which is capable of making wide and thick barrier structures using EVOH and nylon resins. The line can make films up to 32 feet in circumference and sheeting up to 80 mils thick.
The line features Davis-Standard's new ProCone die technology. The dies are engineered in a stackable mandrel arrangement, which enables vertical and angular movement within the stack.
“Our investment in this cutting-edge technology aligns with our commitment to product research and development and inspires barrier membrane advancements by providing exceptional performance and value to the industries we serve,” stated Jim Groninger, vice president and general manager for the Raven Engineered Films division, in a news release.
