Embodiment Construction
[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0029] A low warpage UV-resistant reflective film, comprising a core layer 1, microbubbles 2 are distributed in the core layer 1, and the core layer 1 is composed of the following components according to mass percentage:
[0030] PET: 80%;
[0031] TOPAS6013 produced by Japan Polyplastics Co., Ltd.: 6%;
[0032] Ethylene-ethyl acrylate-glycidyl methacrylate triblock copolymer: 6%;
[0033] Titanium dioxide particles: 8%;
[0034] The low warpage UV-resistant reflective film also includes an upper surface layer 3 and a lower surface layer 4, the upper surface layer 3 covers the upper surface of the core layer 1, and the lower surface layer 4 covers the lower surface of the core layer 1 surface;
[0035] Both the upper surface layer 3 and the lower surface layer 4 are composed of the following components according to mass percentage...
