Hamburg, Germany-based tesa SE and Panasonic Electric Works Europe AG have developed tesa 6926 LTF-C laser transfer film for labeling solar modules with permanent, tamper-proof lettering on glass.
LTF-C film is especially suitable for permanent labeling with various types of information, such as serial numbers or bar codes and matrix codes. These features can be used to clearly identify products over their entire lifespan. Because LTF-C labeling cannot be removed without destroying the glass, serial numbers applied in this way can be used, for example, for dependable checking of warranty claims.
Also, because LTF-C labeling can be applied very quickly and is machine-readable, these types of marking are also suitable for track-and-trace systems in fully automated production environments, the companies add.
