Summary:A laser system and method is used to micro-drill a web producing holes of approximately 85 μm or less. The laser system comprises a laser beam having a wavelength in the range of approximately 2 to 6 microns and the focal point of the laser beam being steered onto a surface of the moving web wherein the web is moving.. The web is a film such as a flexible film or commercial packaging film. The laser beam wavelength and constant laser energy can be used to laser micro-drill the flexible film.
