CastFolie

CastFolie is a family of polymer films designed for casting and molding applications in art, design, and manufacturing. Developed by CastFolie Ltd., the films are intended to be cast against a mold or substrate and then released to form flexible, durable components. The product line includes variants for clear, colored, and metalized finishes.

The composition relies on a flexible copolymer base with surface treatments that provide release properties and compatibility with common resins and adhesives. Variants include CastFolie Standard, CastFolie Ultra (higher tear resistance), CastFolie Clear (optically clear), and CastFolie Metalized (thin metallic foil layer). Some versions feature UV-curable coatings for faster processing.

Produced through roll-to-roll extrusion and lamination, CastFolie films typically range from 0.05 to 0.5 millimeters in thickness. They are generally flexible, exhibit good dimensional stability, and offer chemical resistance. The clear variant emphasizes optical clarity, while other grades emphasize toughness or surface appearance. The films are suitable for thermoforming or thermo-compression and can be integrated with a variety of mold geometries.

Applications span sculpture and prop making, set design, rapid prototyping, lightweight interior components, protective or decorative laminates, and select packaging or electronics shielding. They require compatible release agents and curing or bonding methods tailored to the chosen resin or adhesive system.

Safety and disposal considerations follow standard practices for polymer films. Finished CastFolie products are typically non-toxic, though processing may emit fumes under certain conditions. Recycling options depend on local facilities and the specific film variant. Limitations include processing costs relative to simpler foils and compatibility constraints with some resins or manufacturing workflows.
