Film sticker (panel)

Product related words: film panel, touch panel, self-adhesive sticker, machine surface sticker, button panel, instrument label, equipment control mask, PET/PC nameplate, self-adhesive label, film label, film label

The panel layer is generally made of exquisite patterns and text printed on colorless transparent sheet materials such as PET, PC, etc. less than 0.25MM. Because the main function of the panel layer is to play the role of identification and keys, the selected material must have high transparency , High ink adhesion, high elasticity, high toughness and other characteristics.

Surface adhesive layer

The main function of the surface glue is to closely connect the panel layer and the circuit layer to achieve the effect of sealing and connection. The thickness of this layer is generally required to be between 0.05 and 0.15 mm, with high viscosity and anti-aging properties; in production In general, special membrane switch double-sided adhesive is used, and some membrane switches require waterproof and high temperature resistance. Therefore, the surface adhesive must also use materials of different properties according to needs.
