PP is a kind of board with higher hardness than PVC, and the price of PP material is relatively cheap. Generally used in 3D stationery, 3D gifts, 3D postcards, 3D bookmarks and other products. However, the effect of making 3D stereoscopic printing products is not ideal. PET grating is generally used because of its good permeability, stable performance and better stereoscopic effect than PP ... PVC belongs to soft glue, and super-shadow 3D printing is generally used to make 3D soft glue, 3D anti-counterfeiting labels and so on.
