Nova Installs Nine-Layer Blown Film Line to Enhance Customer Collaboration
It's said to be a first for PE resin producers in North America.
The cornerstone of a broad program of upgrades at the Calgary R&D facility’s Center for Performance Applications of Nova Chemical Corp. (U.S. office in Moon Township, Pa.) is a new Brampton Engineering nine-layer blown film coextrusion line. Aimed at enhancing customer collaboration and product and application development capabilities, the new semi-commercial-scale line enables in-house production of complex multilayer films to optimize coextruded film structures and determine which polyethylene and other materials perform best.
Sarah Marshall, technical services manager, says Nova Chemicals is the first PE resin producer in North America to have a nine-layer line. Dow Chemical Co.’s Film Application Development Center (FADC) in Freeport, Tex. is equipped with a seven-layer Alpine blown film line.
And as with all sciences, there are fundamentals that must be considered to do color right. Here’s a helpful start.
Die buildup, also called die drool, die bleed, or plate-out, can plague any extrusion process.
Newer specialty slip masterbatches go beyond traditional capabilities to provide greater thermal stability, reliability, and ability to hold COF steady during laminating.
