Technical Field

[0001] This utility model relates to a cutting device, specifically a polyurethane film cutting device. Background Technology

[0002] The main component of TPU hot melt adhesive film is polyurethane, an elastomer material. Its color varies depending on the melting point, ranging from high transparency, transparent, to white matte. After preparation, TPU hot melt adhesive film requires performance testing.
