At Pack Expo Chicago Sherwood Technology announced DataLase Clear. In a combination of chemistry and substrate conversion an additive is doped directly into an existing coating or separately coated. This creates a laser imagable transparent layer within the product.
When the coated material comes into contact with the output from a low power CO2 laser, it changes from clear to black, producing a high contrast indelible image.
The additive will be especially useful for the laser coding of transparent films and plastics packaging, believes Sherwood.
The coating may be sandwiched in a laminate at the converter so allowing images to be produced through the film or self-adhesive label whilst retaining the integrity of the uppermost layer. Laser responsive coating within a laminate construction can also bestow a number of overt and covert security features suitable for brand protection.
