In recent years, advances in coextrusion
technology have led to the development of micro- to nano- layered polymeric structures via layer multiplication extrusion [1-3].
Contract notice for Supply and installation of complete lines with coextrusion
systems from Macro Engineering & Technology, Mississauga, Ont.
Another recent development is the AB coextrusion
die which gives a 4:1 blow-up/stretch ratio and D-S says requires fewer blowing agents to achieve a high-density product.
The accompanying figures below show the interface shape (shown in blue color), velocity, and pressure distributions in a complex profile die predicted by the polyXtrue coextrusion
die design module.
TPE monoprofile and coextrusion
lines are also described, along with a rubber-TPE hybrid extrusion system.
The outer-layer forms a material in a coextrusion
method and forms at least one of the outer layers from the outer-layer forming material.

NYSE: GRA) today announced the start up of the A/O Grace Kaustik joint venture's first coextrusion
line at its packaging plant in Volgograd, Russia.
In general, owning the advantage of combining separate features of different individual polymers together in a facile way, technology of coextrusion
has been widely used to fabricate multilayered composite sheets or films for various applications ranging from food packaging products to optical reflective films .
has been pursuing monolayer barrier containers of nylon 6 as a more durable and economical solution than multilayer coextrusion
blow molding or fluorination of monolayer HDPE.
The company says, "The key to the improvements is special tooling developed by EDI to implement a coextrusion
process designed and patented by The Dow Chemical Company.
