This is a piece of 2.4mm thick 3-ply acrylic engravable material. It is fire retardant and slightly more brittle than the conventional 2-ply gravoply materials. They usually come in thickness of 1.5mm, but thickness of 2.4mm or even 3mm is possible upon request.
A very unique QR-Coded industrial label. Made of heat-resistant traffolite material, both engraving and solvent printing are being done to this label.
These fire-resistant traffolite engravable materials have a higher melting point than normal plastic engravable materials like gravoply.
