tesa® 6940 Rapid Laser-Label

High-Speed markable and self-adhesive

Product description

tesa® 6940 is a double layer, brittle acrylic film. 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 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.

The use of a high-speed laser enables a considerably quick marking.
(black and red: up to 4000mm/ sec., yellow: up to 1000mm/sec).

Available in: black (glossy), red and yellow

Main applications

  • Very fast marking is achieved in conjunction with high-speed laser hardware
  • High contrast and excellent marking precision
  • Very resistant to heat, abrasion and chemicals
  • Tamper Evident: Manipulation leaves visible trace
  • Not removable without destruction of the label
  • Flexible formatting and label design: marking and cutting by the laser
  • Efficient: replaces a multitude of pre-made labels
  • Just-in-time production reduces storage needs
