The invention relates to the technical field of packing bags, in particular to a breathable plastic bag. A plastic bag body successively comprises an outer surface layer and an inner surface layer from outside to inside, a layer of breathable channels is formed between the outer surface layer and the inner surface layer, a plurality of air holes through which the outer surface layer is connected with the inner surface layer are formed in the surface of each breathable channel, a layer of breathable films is arranged on the surfaces of the air holes, and the breathable channels are arrayed in a groined manner. The breathable plastic bag comprises the plastic bag body and a handheld part; the plastic bag body successively comprises the outer surface layer and the inner surface layer from outside to inside; the layer of breathable channels is arranged between the outer surface layer and the inner surface layer; by the added breathable channel structures, breathability of the plastic bag is improved; when vegetables and fruits are placed in the breathable plastic bag, the storage time is long; moreover, when children play the breathable plastic bag, safety is improved; the air holes through which the outer surface layer is connected with the inner surface layer are formed in the surface of each breathable channel; the layer of breathable films is arranged on the surfaces of the air holes; and by the breathable films mounted on the air holes, the breathability of the plastic bag is improved further.
Description
technical field [0001] The invention relates to the technical field of packaging bags, in particular to a breathable plastic bag. Background technique [0002] When purchasing items, plastic bags are often used. Most of the existing plastic bags do not have air permeability. The restrictions, which bring inconvenience to the use and storage of items. [0003] Patent No. 201120389106.7 discloses a ventilating plastic bag, comprising a plastic bag, a plastic bag is provided with a vent hole, and a ventilating film block covering the vent hole is fixed on the vent hole; the gas permeability of the ventilating plastic bag still needs to be improved, The quality of plastic bags needs to be improved. Contents of the invention [0004] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide a breathable plastic bag with good air permeability and good quality. [0005] In order to achieve the above object, the tec...
