Signage, as a core carrier of information transmission, is widely used in various scenarios including commercial advertising, traffic guidance, public services, and industrial warnings. Its diverse and complex operating environments demand stringent requirements for material weather resistance, durability, processing adaptability, and environmental friendliness. Ultra-high molecular weight polyethylene (UHMWPE) and high-density polyethylene (HDPE), with their complementary performance advantages, have become the preferred engineering plastics for the signage industry. They are suitable for long-term stable use in extreme outdoor environments while also meeting the lightweight and aesthetic requirements of indoor signage, driving the upgrade of signage products towards high performance, green materials, and scenario-specific applications.
