PET Laser Marking Additive Masterbatch

PET Laser Marking Masterbatch is a specialized additive concentrate designed to enable high-contrast, permanent markings on Polyethylene Terephthalate (PET) products using a laser beam. Without it, PET is generally difficult to mark with lasers because it tends to carbonize poorly and produces low-contrast, faint marks. The masterbatch contains sensitive additives that react dramatically to the laser's energy, creating a clear, precise, and durable mark on the PET substrate. How Does It Work? The process is based on a chemical reaction triggered by the laser's heat: Energy Absorption: The additives within the masterbatch (e.g., metal oxides) are highly absorbent of the specific wavelength of the laser (commonly fiber lasers at 1064 nm). Localized Reaction: The concentrated laser...
