Marked with the FH "Index" marking head and Synrad laser, using  7 watts at 15"/second.

This mark, made in thin film, highlights the excellent readability of polyester. The resulting opaque mark, created by the melting and resolidification of the material, contrasts against the translucent film as light passes through the material. Equally good marks may be achieved on thick polyester.
