tesa® 6957 Laser-Label
High heat resistant, high-speed markable and fraud-resistant
Product descriptiontesa® 6957 is a double layer, brittle acrylic film with watermark. Customised and fraud-resistant information, such as company logo, is permanently embedded in the backing. Marking and cutting are achieved by laser in one step, which makes it possible to realise any desirable label variation and format using only one material. The backing is highly resistant against chemicals, abrasion, temperature and aging.
The adhesive system consists of a resin modified acrylic suitable even for low energy surfaces. The adhesive will leave an UV-detectable trace (“UV-Footprint”) on most surfaces as required by GB 25978 (P.R.C.) and NHTSA §541.5 (USA).
The use of a high-speed laser enables a considerably quick marking up to 4000mm/ sec.
Available in: black
