PET Coated Base Film is a specialized polyester film featuring precision-engineered surface coatings that enhance functionality and processing characteristics. This premium film combines the excellent mechanical properties of PET with advanced coating technologies that modify surface properties to achieve superior printability, adhesion, barrier performance, or specialized functionality depending on the specific coating formulation applied.
Our advanced coating processes ensure uniform and consistent application of functional layers that are firmly bonded to the PET substrate. The coatings can be customized with various formulations including acrylic, PVDC, silicone, and specialized polymers to achieve specific performance characteristics for different applications. These coatings modify the film's surface properties while preserving the underlying mechanical strength and dimensional stability of the PET substrate.
Available in thicknesses ranging from 12μm to 125μm, our PET Coated Base Film offers exceptional performance enhancements for converting, printing, and functional applications. The coated surfaces can be designed for optimal ink receptivity, heat sealing properties, barrier protection, or release characteristics. Its combination of enhanced surface properties and robust PET substrate makes it ideal for demanding applications in packaging, labeling, and industrial uses where standard untreated films would not perform adequately.
