4.5μm High-Performance BOPET TTR Base Film

I. Product Overview

Our Ultra-Thin BOPET Series serves as the premium foundational carrier for high-quality Thermal Transfer Ribbons (TTR) and Hot Stamping Foils. It is engineered to act as a high-heat resistant skeleton for Wax, Resin, and Metallic layers, ensuring high-fidelity transfers in luxury packaging and industrial labeling.

II. Core Technical Advantages

• Exceptional Thermal Integrity: Engineered to withstand intense print-head heat with a low shrinkage rate ( at °C). This prevents warping and ensures precise registration for multi-color and holographic transfers.
• Superior Mechanical Tensile Strength: High (Machine Direction) tensile strength allows for gauges as thin as 3.5μm–4.5μm without snapping, even on high-speed slitting and coating equipment.
• Joint-Free Manufacturing: We provide continuous rolls up to 55,000–65,000 meters without a single joint. This maximizes "Up-Time" for coaters by eliminating machine stops and potential blade damage.
• Surface Consistency & Adhesion: Controlled surface tension (High Dyne level) provides an ideal substrate for both back-coatings (protecting the print head) and the ink-release layer.

III. Specifications & Logistics

IV. Advanced Application Suitability

1. Near-Edge Printing: Optimized for rapid-release at high speeds, critical for modern TTO (Thermal Transfer Overprinting) in food packaging.
2. Resin-Based Ribbons: The high glass transition temperature () of our PET supports the high energy levels needed for pure resin ink melting.
3. Hot Stamping & Anti-Counterfeiting: A reliable carrier for the complex multi-layer structures of holographic foils used in luxury tobacco, liquor, and pharmaceutical packaging.
