1. Title: Biaxially oriented polypropylene based film for laser embossing transfer patent application number 0
Abstract: The utility model relates to a biaxially oriented polypropylene base film used for laser imprint transfer. The base film is composed of an upper surface layer, a core layer, and a lower surface layer. The upper surface layer, core, and lower surface layer are integrated by hot melt coextrusion. The following table shows the transfer layer. The thickness of the upper surface layer and the lower surface layer of the base film is respectively 10% to 2% of the thickness of the base film. The advantage of the utility model is that due to its reasonable structure and novel design, it can directly carry out laser imprint transfer. The utility model not only satisfies the laser effect, vapor deposition effect and transfer effect required by the user, but also greatly reduces the cost of the product.
