EDI® MA-CARR Adjustable Geometry Coextrusion Feedblocks

Nordson's MA-CARR feedblock design offers processors innovative features to help increase production speed with rotating restrictor bars, while optimizing layer thickness with removable inserts.


  • Combine polymers in a parallel path manner to gain optimal layer ratio stability throughout the structure
  • Easily adjust production speed with rotating restrictor bars located at layer combining point



  • Designed to allow entrance locations to be customized, creating flexibility in the line design and layout 
  • Selector spool or cassette features allow layer sequence arrangements to be preset upstream of the combining point in the feedblock without removing the block from the line
  • Compatible with EDI Layer Multiplication Technology (LMT), which offers the largest operating window with the smallest physical space requirement in the marketplace
  • Removable inserts allow for layer thickness optimization
  • Designs are available for up to 11 layers and can accommodate as many as 8 extruders
  • 30% layer ratio adjustability (without downtime)
  • Ideal for Barrier Film, Barrier Sheet, and Extrusion Coating & Laminating applications
