Laser marking technology for laundry detergent bottles uses lasers to accurately mark the surface of plastic bottles or bottoms, commonly found in high-density polyethylene or polyester materials. The marking content mainly includes key information such as production date, shelf life, batch number, and traceability barcode. Laser causes surface materials to change color or slightly foam through chemical reactions, forming permanent, clear, and chemically resistant markings. This method is ink free, environmentally friendly, and can effectively resist the erosion of humid environments and detergents themselves. It eliminates the problem of information blurring and falling off caused by friction or content immersion in traditional ink coding, ensuring the readability of product information throughout the entire circulation and use cycle, and providing reliable guarantee for quality tracking and consumer identification.
