tesa® 6957 PV1 Black Glossy FPA

Product description

tesa® 6957 is a high heat resistant two-layer, brittle acrylic laser markable film with a unique, forgery-proof watermark design that is embedded into the material as prove of originality.

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 product is highly durable and resistant against thermal, chemical, mechanical and environmental (weathering) influences for secure traceability over entire vehicle lifetime.

The adhesive system consists of a special acrylic adhesive system, which leaves an UV-detectable trace (“UV-Footprint”) on most surfaces as required by GB/T 25978 (P.R.C.) and NHTSA §541.5 (USA).

Application Fields

Depending on the type of application, our laser markable films are available in different grades, either for standard warning and instruction content or for demanding theft relevant vehicle identification and certification labels and anti-theft part marking.

tesa® 6957 is specially designed to also fulfill the requirements of GB/T 25978 (P.R.C.) for F-Type labels (engine and transmission).

This high-performance product is used as a tamper evident vehicle identification and certification label as well as anti-theft parts marking for secure traceability over the entire vehicle lifetime.
