Seven-Layer Barrier Sheet Line Installed
January 18, 2012
Raven Industries Engineered Films Division has installed and started up its newest blown sheet line, reportedly the world's largest seven-layer barrier system.
The Sioux Falls, S.D.-based company worked extensively for 18 months with industry experts Davis Standard LLC, Pawcatuck, Conn., to plan, design and develop the highly complex engineered equipment.
According to the company, Raven's new line is capable of processing the widest and thickest (EVOH, nylon) barrier structures available. It can produce films up to 32' in circumference and sheeting up to 80 mils thick with optional surface texturing available. This machine houses a 60" diameter, seven-layer Centrex die manufactured with the latest extrusion technology and engineered to provide maximum versatility utilizing seven individual extruders for the production of barrier sheeting.
