The color developing substance can be fluorescent powder, color paste and the like, as long as the color of the film matrix can be changed.
Optionally, the film substrate is a polyethylene film, an oriented polystyrene film, or a polyester film. The polyethylene film (PE film for short) is thermoplastic plastic, is a material with good toughness, and is not easy to crush by a common plastic crusher. Oriented polystyrene film (OPS film for short) is a novel skin packaging material which meets the requirement of environmental protection, and the OPS heat shrinkable film has the advantages of high strength, large rigidity, stable shape, good glossiness and transparency, and convenient processing and easy coloring.
