NOVELTY - The utility model model claims a novel battery diaphragm PET film, comprising a PET base layer main body, the upper and lower ends of the PET base layer main body are fixedly mounted with a barrier layer main body, the barrier layer main body is provided with two, and one side of the two barrier layer main body opposite to each other is fixedly mounted with a high-strength bonding layer, the high-strength bonding layer is provided with two, and one side opposite to the two high-strength bonding layer is fixedly installed with an ultraviolet ray-stop layer main body. The utility model can be through high intensity of the bonding surface layer to bonding protective surface layer, at the same time, it can prevent the layer main body to isolate the sunlight and the ultraviolet by the ultraviolet, avoiding the sunlight directly irradiated to the battery, at the same time, when taking the film, can through the fingerprint-proof adhesive layer main body to protect the film, to avoid the fingerprint sticking, at last, it can protect the periphery of the film through the first section protection surface layer and the second section protection surface layer avoiding collision.
