PET/PVA two-layer film "SO Sheet"

Water-soluble sheet: By combining with PET, dimensional stability has increased, allowing for the maintenance of fine structural shapes!

The "SO Sheet" is a film made of a two-layer structure of PVA and PET. It can be utilized as a transfer substrate for functional patterns created through various printing and coating processes on the PVA layer (such as resist, metal, functional resins, etc.). Applications as a "water-soluble" process sheet are expected for three-dimensional lithography, extraction of sacrificial layers and self-supporting films, and temporary protection during processes. 【Features】 ■ Removable two-layer structure: Separation of the water-soluble layer and support layer is possible. ■ High dimensional stability: The support layer suppresses dimensional changes due to swelling and shrinkage from moisture absorption and desorption of PVA. ■ Smooth and high transparency: Light transmittance of 90% (visible light), surface roughness Ra of the PVA layer ≓30nm. ■ High printability: Wetting tension of 58mN/m or higher. *For more details, please refer to the related links or feel free to contact us.
