tesa® 6940 PV3 silver glossy/ black
High-speed laser markable film
Product Features
- Marked irreversible by laser with excellent long-term legibility by the human eye or scanning devices
- High contrast and marking precision support the realization of even the smallest letters, numbers and symbols, even 2D-bar codes (data matrix, QR codes)
- Manipulation leaves visible trace (damage on information and label) to prevent re-using
Product description
tesa® 6940 PV3 Silver glossy/ black is a two-layer high-speed laser markable film with an acrylic adhesive. The brittle product construction ensures that the label is destroyed upon any attempt of removing and tampering and leaves a visible trace (damage of information and label).
Marking and cutting are achieved by laser in one step, which makes it possible to realize any desirable label variation and format using only one material. The top layer allows for high marking speed (up to 4000mm/sec.).
