Abstract
The utility model relates to a cell package film having a laser holography anti-counterfeit function. A holographic shaped solidified layer is coated on a thermal shrinkage skin layer. A reflecting layer, a binding layer, a thermal shrinkage bottom layer, a binding layer and a shape separating layer are respectively coated after the holographic shaped solidified layer. The holographic shaped solidified layer can also be coated on the thermal shrinkage bottom layer. Heat-shrinkable materials, such as PVC, PET, POF, etc., can be adopted by the thermal shrinkage skin layer and the thermal shrinkage bottom layer. The utility model can be divided into a common holographic type and a transparent holographic type according to different reflecting layer materials. Shaped holographic videotex can be directly imprinted on the non-heatproof materials by adopting a cold pressing solidified mode. The speed of the entire process is fast, and the structure of the original cell package film can not be destroyed. The production efficiency is high. In the process of thermal shrinkage, the holographic layer is protected by an outer layer film so as to keep the original holographic effect. Under the situation of not changing the battery production package technology and the basic battery package appearance, a stronger anti-counterfeiting function is increased in the utility model.
