Global circular economy policies accelerate the popularization of recycled plastics in manufacturing, bringing new technical challenges and market opportunities for laser marking functional material industry. Recycled polymer materials have complex component composition, unstable impurity content and poor thermal stability. Conventional laser marking masterbatch often leads to uneven marking, low contrast and frequent bubble defects when applied to recycled plastics, restricting the large-scale use of recycled materials in high-end products.
Targeting the characteristics of post-consumer recycled resins, R&D teams develop special modified laser marking additive systems. The optimized dispersant composition improves compatibility between laser absorbers and heterogeneous recycled polymer blends. The formula inhibits thermal decomposition impurities inside recycled materials during laser irradiation, effectively reducing marking defects. The new series of additives can realize stable White-on-Black, Black-on-White effects in recycled PP, ABS and PC materials, helping downstream manufacturers increase the proportion of recycled plastics while satisfying product identification requirements.
Many brand enterprises set clear targets to lift recycled material usage rate. Laser marking performance becomes an important technical indicator when manufacturers select recycled plastic formulations. Material suppliers carry out extensive compatibility tests for recycled materials from different recycling channels, forming targeted application schemes. With the continuous advancement of carbon emission reduction policies, demand for recycled plastic-compatible laser marking materials will maintain rapid growth. Relevant technical achievements will support the low-carbon transformation of plastic processing industry and promote the sustainable development of functional material sector.
