Processing Information
Release Properties
Our PET Hot Stamping Base Film is engineered with carefully controlled surface chemistry to provide optimal release properties for various foil types. The release properties can be customized to achieve different levels of adhesion, allowing for clean separation of the carrier film after the hot stamping process.
Hot Stamping Process
The film performs optimally at stamping temperatures between 100-200°C, depending on the specific foil type and substrate material. For best results, stamping parameters (temperature, pressure, and dwell time) should be optimized for each specific application. Our technical team can provide guidance on process optimization for different decorative effects.
Storage and Handling
Store in a cool, dry place away from direct sunlight. Recommended storage conditions: temperature 15-25°C, relative humidity 40-60%. The shelf life is 12 months when stored correctly. For optimal performance, acclimatize the film to the processing environment for 24-48 hours before use.
