Drawings
FIG. 1 is a schematic perspective view of a preferred embodiment of the UV-blocking packaging film of the present invention;
the parts in the drawings are numbered as follows: 1. microporous membrane layer, 2 waterproof layer, 3 adhesion layer, 4 groove.
Detailed Description
The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.
Referring to fig. 1, an embodiment of the present invention includes:
the utility model discloses an ultraviolet ray separation packaging film, include: the waterproof coating comprises a microporous membrane layer 1, a waterproof layer 2 and an adhesion layer 3; wherein, the waterproof layer 2 and the adhesive layer 3 are respectively attached to two sides of the microporous membrane layer 1.
The microporous membrane layer 1 is a fully degradable polyethylene plastic film doped with an ultraviolet reflecting agent, and the ultraviolet reflecting agent is nano zinc oxide. The thickness of the microporous membrane layer 1 is 50-500 mu m; a plurality of micropores are uniformly distributed in the microporous membrane layer, the distribution number of the micropores in the unit volume of the microporous membrane layer 1 is 2-5, and the aperture of each micropore is 2-10 mu m. The microporous membrane layer plays a role in preliminarily reflecting ultraviolet rays by doping the ultraviolet reflecting agent nano zinc oxide, and effectively reflects ultraviolet rays by improving the design of a microporous structure, namely, the microporous membrane layer has a function of doubly reflecting ultraviolet rays.
The adhesive layer 3 is a silica gel film layer, and grooves 4 distributed at equal intervals are formed in one side, away from the microporous film layer 1, of the adhesive layer 3; the depth of the groove 4 is smaller than the thickness of the adhesive layer 3. By the design of the grooves 4, the surface area of the adhesive layer is increased, thereby functioning to mention the adhesive force.
The utility model relates to an ultraviolet ray separation film, simple structure, reasonable in design, its micropore rete passes through the design of microporous structure and the use of ultraviolet reflecting agent, realizes the ultraviolet function of dual separation, and fundamentally has improved the ultraviolet protection performance of film, and the practicality is strong.
