VCF films, Inc. is a manufacturer of various thin film materials including acrylic films, cellulose acetate butyrate (CAB) films, polycarbonate (PC) films, polyetherimide (PEI) films, and polysulfone (PSU) films. Laser processing of VCF films can be performed using a 9.3 or 10.6 micron CO₂ laser without a noticeable difference in process quality. Laser processing of VCF films with a 1.06 micron fiber laser is not recommended as most of the materials produced by VCF do not readily absorb the energy produced by this wavelength of laser. Because of the very thin nature of all of the films produced by this manufacturer, laser cutting of VCF films produces a clean cut edge without any noticeable discoloration or heat affects. Laser engraving and laser marking of VCF films is not recommended due to the thickness of these materials.
