Producing biaxially oriented film for flexible and consumer packaging is one of the most demanding flat Die extrusion applications. Good layer-to-layer distribution and overall gauge caliper consistency is a must and critical in the orienting process.

Through our intimate understanding of this production process, we are able to help our customers continually increase production rates over an evolving range of polymers and structures. We offer the Industry’s most extensive combination of Feedblocks, and Single and Multi-Manifold Dies, giving processors the greatest flexibility in film configuration to meet their customers’ needs.

Our innovations drive nonstop acceleration in production rates while maintaining excellent layer-to-layer gauge uniformity and precise thickness control.

Our specialized technologies for biaxially oriented films include:

• Multi-Manifold Dies for the most uniform layer-to-layer gauge control and the ability to individually control layer width via our Fixed Length Deckle System.
• Feedblock designs that handle conventional two and three layer films or the complexity and sophistication of hundreds of nano-layers.
• AutoGauge™ lip adjustment system for precise, computer-managed web thickness profile control.
• Removable prelands that allow the Die flow channel geometry to be changed easily to accommodate new polymer processing requirements driven by changing market demands.
• Strong Back™ Die designs that permit extrusion of high viscosity polymers with minimal mechanical deflection or distortion of the Die.

Cloeren supplies Dies for processing a broad range of polymers, including biaxially oriented polyamide, polyethylene terephthalate, polystyrene and polypropylene.
