Co-extrusion co-extrusion die EPC™

for extrusionfor laminatingfor coating

Overview
Processors face challenges ensuring uniform coating or laminating material distribution across the web width while avoiding flooded or starved edges. EDI® EPC™ die systems are custom designed to control edge profile, reduce edge bead and trim, maintain consistent polymer distribution and improve process stability and material yield.

Key benefits

• Reduce trim and material waste by minimizing edge bead and enabling precise edge flow control.
• Improve process stability through uniform polymer distribution across the substrate width.
• Faster servicing and easier cleaning with deckle and die-body designs that limit fastener removal and provide rapid access.
• Adaptable integration to new or existing production lines to meet specific production parameters.

Features at a glance
Coextrusion & Gauge Control
Coextrusion Capabilities: Die mates with Ultraflow™ V-T adjustable or Ultraflow™ I fixed-geometry feedblocks and integrates with EDI® Layer Multiplication Technology (LMT).
Gauge Control: Prodigi™ motorized lip actuator, Autoflex™ automatic or manual lip adjustment systems available.

Designed to Suit Your Process
Deckling Capabilities: EPC™ dual deckle system (internal with external back-up) for enhanced sealing and fine flow control to die ends.
Finishing Options: Multiple surface finishes available, including chrome plating or alternative coatings depending on application.
Production Line Integration: Adaptable interfaces for new or existing lines.
Additional Features: Optional motorized deckle drive available for the EPC™ system.

How EPC™ Benefits Production

• Minimize Trim Width — Internal deckle blade system allows quick product-width adjustment and precise flow control at die ends to reduce edge beads to minimal amounts.
• Increase Extruder Uptime — Limited fasteners for deckle access minimize downtime; retractable deckle assemblies permit insertion of custom brass scrapers for efficient lip cleaning.
• Operational Simplicity — Designs consider operation and maintenance to deliver robust, easy-to-operate equipment with superior edge-profile control.

Application Areas

• Extrusion coating and laminating lines for flexible packaging and technical films.
• Processes requiring coextrusion (multi-layer structures) and precise gauge control.
• Operations seeking to reduce trim, scrap and material costs while improving uniformity.

Associated Technologies / Options

• Ultraflow™ V-T adjustable and Ultraflow™ I fixed geometry feedblocks.
• EDI® Layer Multiplication Technology (LMT) for multilayer constructions.
