Embodiment Construction
[0018] In order to make the objectives, technical solutions, and beneficial effects of the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and not used to limit the protection scope of the present invention.
[0019] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the present invention provides a polyethylene mother-and-child insulation film, which includes a film body and a connecting portion fixedly connected to the film body. The connecting portion includes a female strip provided on the upper surface and a lower surface. The sub-strip, the mother strip includes a card slot, and the sub-strip includes a card head matched with the slot structure.
[0020] The thermal insulation film described in the present invention is generally produced in units of sheets in ac...

The invention discloses a polyethylene male-female heat insulation membrane which comprises a membrane body and further comprises a connecting portion fixedly connected with the membrane body. The connecting portion comprises a female strip arranged on the upper surface and a male strip arranged on the lower surface, wherein the female strip comprises a clamping groove, and the male strip comprises a clamping head structurally matched with the clamping groove. The polyethylene male-female heat insulation membrane has the advantages that due to the facts that the connecting portion is arranged on the membrane body, and the connecting portion comprises the female strip and the male strip which correspond to each other in shape and can be fixed together, sealing connection between a plurality of heat insulation membranes and sealing connection of the single heat insulation membrane can be achieved, the sealing effect is good, the operation is easy, the production efficiency can be improved, and the polyethylene male-female heat insulation membrane has the significant popularization significance in application scenarios such as agriculture, environmentally-friendly facilities and factory workshops.
Description
Technical field [0001] The invention belongs to the technical field of production and life, and particularly relates to a polyethylene mother and child heat preservation film. Background technique [0002] With the development of modern technology, polyethylene insulation film is widely used in various technical fields in production and life. In the process of using the above-mentioned polyethylene thermal insulation film, because the area of the thermal insulation film product produced is limited, in some occasions, such as when used in a greenhouse, it is necessary to connect multiple thermal insulation film products for use. [0003] In the prior art, the insulation film products are often connected by folding, tying, bonding, etc. However, these connection methods have some disadvantages. For example, after the connection is connected by bonding, the bonding is not tight and it is easy to disconnect; After the binding is connected, the insulation film is wasted, the sealing ...
