The invention provides a PE film, which comprises a PE membrane body, wherein the PE membrane body comprises an upper layer, an intermediate layer and a lower layer arranged in sequence from top to bottom, and also comprises a first absorbing ultraviolet anti ageing layer arranged on the upper surface of the upper layer and a second absorbing ultraviolet anti aging layer arranged on the lower surface of the lower layer.The first absorption ultraviolet anti aging layer and the second absorbing ultraviolet anti aging layer are respectively arranged on the upper and the lower surfaces of the PE membrane body, and the ultraviolet light can be absorbed by the sunlight through the PE film to achieve the growth temperature required for the growth of the crops on the ground surface, and the ultraviolet light of the sunlight scattered on the ground surface is also absorbed, thereby preventing the PE film from being irradiated by ultraviolet radiation. Aging and crushing to maintain its original physical properties and integrity.Moreover, the setting of three layers of PE mulching film can keep good tensile and toughness properties, thus providing auxiliary conditions for the use and recycling of PE mulching film.本發明提供了一種PE地膜，包括PE膜本體，PE膜本體包括從上而下依次設置的上層、中間層和下層，還包括設置於上層上表面的第一吸收紫外抗老化層和設置於下層下表面的第二吸收紫外抗老化層。通過在PE膜本體的上、下表面分別設置第一吸收紫外抗老化層和第二吸收紫外抗老化層，可在太陽光透過PE地膜而達到地表給農作物提供生長所需的溫度時對其紫外光進行吸收，同時對於地表散發的太陽光的紫外光也給予吸收，從而防止PE地膜在受到紫外光輻射後被老化及粉碎而維持其原始物性及完整性。且通過PE地膜本體三層的設置可以使PE地膜保持較好的拉伸及韌性性能，因而爲PE地膜的使用回收提供了輔助條件。
