Label Materials

Calibration seals manufactured from 'Void' polyester or 'Ultradestructable' Vinyl are produced in any shape or size required, printed with full colour logo's or text.

VOID Polyester Labels have a hi performance adhesive that reveals the word VOID when the label is lifted or removed, this prevents label transfer or denial of intrusion into a warrantied product.

Ultradestruct Vinyl Labels have a very hi tack adhesive and fragent upon attempted removal, excellent as a visual seal or screwhead cover.
