The present disclosure includes a stretchable reflective film comprising a transparent polymer layer; a continuous metal layer comprising at least one of tin or indium; a non-reactive adhesive layer;and a stretchable film layer. The stretchable reflective film has at least 30% specular reflectivity when stretched by 50% of the unstretched length according to Specular Reflectivity Test Method.
本公开包括一种可拉伸反射膜,该可拉伸反射膜包括:透明聚合物层;连续金属层,该连续金属层包含锡或铟中的至少一者;非反应性粘合剂层;以及可拉伸膜层。根据镜面反射率测试方法,当该可拉伸反射膜被拉伸未拉伸长度的50%时具有至少30%的镜面反射率。
