High Clarity Printable PET Film with 56.0 mN/m Wetting Tension and 100/100 Cross-Cut Adhesion for Membrane Switches
HT10 50 μm PET film is a high-clarity BOPET film designed for membrane switch printing, electronic insulation, precision die-cutting, and thin structural applications. With excellent compatibility with UV and conventional inks, this printable PET film combines strong surface adhesion, dimensional stability, flexibility, and electrical insulation.
For membrane switch manufacturers, choosing the right PET film can help reduce common production problems such as poor ink adhesion, printing misregistration, film deformation, and unstable converting.
HT10 offers a wetting tension of 56.0 mN/m, supporting good ink wetting and adhesion. This helps reduce uneven ink coverage and printing instability when the PET film is used with compatible UV or conventional ink systems.
A 100/100 cross-cut adhesion test result indicates strong surface adhesion performance under the stated test conditions. This helps reduce the risk of peeling during printing, die-cutting, laminating, and downstream processing.
Dimensional changes can cause printing misregistration and layer alignment problems. HT10 50 μm PET film provides good dimensional stability to support precision printing, die-cutting, and multi-layer assembly.
With a reported dielectric breakdown voltage of 263 V/μm, HT10 can be evaluated as a thin PET insulation film for selected electronic applications. It may help provide electrical separation between conductive components while keeping the overall assembly thin and flexible.
