Huatao Group Stripping Roll

The transition zone where the hot, semi-solid polymer melt leaves the main chill roll is highly sensitive to tension fluctuations. Our Stripping Roll is engineered to deliver a uniform, micro-calculated release force across the entire face width, eliminating optical distortions and physical distortions on delicate packaging and functional film webs.

Key Features

Advanced Low-Surface-Energy Coatings: Available with tailored non-stick treatments (including high-release chrome plating, specialized thermal spray ceramics, or cross-linked PTFE jackets) that prevent additives and wax from sticking to the roller shell.

Precise Speed Synchronization & Core Integrity: Machined from high-rigidity steel or inertia-reducing aluminum alloys, the roll minimizes rotational resistance, allowing it to sync perfectly with line speeds up to 600 m/min to eliminate micro-slip scratches.

Sub-Micron Geometric Profiling: Coaxiality, cylindricity, and straightness are tightly restricted to within ≤0.01mm. This absolute precision prevents local tension spikes and web flutter, which can trap air bubbles or cause film edge tearing.

Effective Thermal Stabilization: Optimized structural design resists localized heat transfer from the freshly cast web, ensuring that the geometric profile remains completely unwarped during continuous 24/7 industrial production.

Target Applications & Industry Scenarios

This high-performance Stripping Roll is engineered for seamless integration with global premier film extrusion lines, optimized for:

BOPP & BOPET High-Speed Lines: Facilitating stable, distortion-free thick sheet peeling at the casting station before orientation.

CPP & CPE Cast Film Production: Preventing low-molecular-weight polymers from sticking during high-temperature cast extrusion.

Lithium Battery Separators (Wet/Dry Process): Securing clean separation of oil-rich or gelled sheets without disrupting pore-forming structures.

Coating & Lamination Machinery: Serving as the release/take-off roller for high-tack adhesive and co-extruded barrier films
