tesa® 6937 Laser-Label

Fraud-resistant watermark

Product description

tesa® 6937 is a double layer, brittle acrylic film with watermark. Customised and fraud-resistant information, such as company logo, is permanently embossed 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 ageing. The adhesive system consists of a resin modified acrylic suitable even for low energy surfaces.

This high performance product is used as a tamper evident identification label over the entire lifetime of a product and also as a data carrier system for intelligent in-process steering.

Available in: black or silver
