PET Metallized Base Film is a high-performance polyester film specially engineered for vacuum metallization applications. It features exceptional surface smoothness, excellent flatness, and optimal adhesion properties to ensure superior metallization effects. Our specialized film undergoes controlled surface treatment and precise thickness profiling, making it an ideal substrate for aluminum vapor deposition.
Our PET Metallized Base Film provides outstanding optical properties with consistent transparency and low haze values. The film's excellent dimensional stability during the metallization process ensures consistent quality of the final metallized product. Additionally, our film features exceptional mechanical strength with high tensile properties in both machine and transverse directions.
We offer this film in thicknesses ranging from 12μm to 36μm with widths up to 8.7 meters. The film can be produced with corona treatment on one or both sides to enhance ink adhesion for printing applications. Our PET Metallized Base Film is ideal for creating high-quality metallized films for flexible packaging, decorative applications, and various industrial uses requiring superior barrier properties.

Processing Information
Metallization Performance
Our PET Metallized Base Film is optimized for vacuum metallization processes. The film's smooth surface and excellent flatness ensure even metal deposition and superior metal adhesion. The film can achieve optical density (OD) values of 2.2-3.0 after metallization, providing excellent barrier and aesthetic properties.
Printing and Converting
After metallization, the film can be easily printed using various printing methods including flexographic, gravure, and offset printing. The treated surface provides excellent ink adhesion for high-quality printing results. The film can also be laminated with various substrates to enhance barrier properties and mechanical performance.
Storage and Handling
Store in a cool, dry place away from direct sunlight. Recommended conditions: temperature 15-25°C, relative humidity 45-65%. The shelf life is 12 months when stored correctly. For optimum metallization performance, it is recommended to use the film within 6 months of production. Handle with care to avoid surface scratches which could affect metallization quality.
