Decoding the Vacuum Forming, Deep Draw Ratios, and Fold Stability of High-Performance Polyester Film
Product Overview
Traditional BOPET film is known for its rigidity and strength, but ask it to stretch into a complex 3D shape, and it usually fails. Lumirror F865 PET Film changes the game entirely. As a biaxially oriented polyester film specifically engineered for in-molding, it combines the optical and mechanical benefits of PET with the flexibility required for deep drawing and vacuum forming. Whether you are creating complex packaging or precision paper crafts, F865 provides unmatched dimensional stability after folding, breaking the boundaries of traditional film conversion.
The Core Specs: Engineering for 3D Forming
What makes Lumirror F865 a marvel in material science? The data sheet highlights a highly specialized performance profile:
- Exceptional In-Mold & Deep Draw Performance: F865 features a deep drawing ratio of up to 1:1 during vacuum molding. This means it can be heated and stretched into deep, complex 3D shapes without tearing or thinning out unevenly.
- Ultimate Fold Stability: Unlike standard films that spring back, F865 maintains its shape when folded. It is so dimensionally stable after creasing that it is ideal for high-end paper crafts and rigid packaging.
- Optimized Surface Treatment (Corona Treated): One side is corona treated to guarantee excellent adhesion for printing inks, adhesives, and laminations.
- Tailored Friction Coefficients: With specifically controlled inside and outside friction coefficients, it ensures smooth handling and prevents blocking during automated processing.
Key Applications Across Industries
The unique moldable properties of Lumirror F865 make it indispensable for:
- Vacuum Form Packaging: Used for lamination (inside and outside) to create protective, thermoformed packaging for industrial and consumer goods.
- Paper Crafts & Luxury Packaging: Perfect for intricate folding, die-cutting, and high-end decorative wrapping.
- Specialty Laminates: Where a thermoformable polyester base is required to support complex shapes.
Important Sourcing Note
Please note that according to the specifications, this film is not guaranteed by the FDA for direct food contact. It should not be used in direct contact with foods.
Sourcing a Reliable Alternative
While Lumirror F865 is the gold standard for thermoformable PET, global buyers often seek a Lumirror F865 Alternative to optimize costs. A successful replacement requires a manufacturer that can precisely replicate the specific thermoforming behavior (1:1 deep draw) and the fold stability, without sacrificing surface quality.
