Please refer to FIG. 4 A in conjunction with FIG. 4 B, wherein FIG. 4 A is a schematic three-dimensional structure diagram of a double-sided film according to an embodiment of the creation, and FIG. 4 B is a top perspective view from the direction a-a'. As shown in FIGS. 4A and B, the relationship between the first release layer 41 , the adhesive body 43 and the second release layer 45 is roughly similar to that of the first embodiment of the present invention, but in this embodiment, the adhesive body 43 The width of the second end 432 and the width of the second edge 412 of the first release layer 41 are both W2, and the width W2 is greater than the width W1 of the first end 431 of the adhesive body 43, that is, W2 is greater than W1 , this can also avoid the problem that the user accidentally removes the first release layer 41 when the second release layer 45 is torn off, so that the adhesive body 43 is not attached, and it is also convenient for the user to stick After the adhesive body 43 and the adherend, such as the cold air filter, the first release layer 41 can be easily torn off from the first edge 411 of the first release layer 41 .

In addition, the design of the first and second ends of the adhesive body with different widths in the fourth picture of this creation can also be matched with the chamfered R angle in the third picture of this creation, so as to ensure that the user is not left with the second release layer when removing the second release layer. Accidentally took the first release layer away together.

Of course, other variations can be made in this creation, which are not limited to the convex-shaped design of the adhesive body 43 in FIG. 4B. For example, as shown in Figures C and D, the width of the second end of the adhesive body is the same as that of the second edge of the first release layer, but its width is greater than the width of the second end of the adhesive body. One end, in other words, the adhesive body can be tapered or bullet-shaped, for example, the width of the first end is smaller than the width of the second end, but the width of the second end is equal to the width of the second edge of the first release layer. All designs can be applied to the present creation to prevent the user from taking off the first release layer by mistake when tearing off the second release layer, and also to facilitate the user to stick the adhesive body 43 and the adherend, for example: After the cold air filter, the first release layer 41 can be easily torn off by the first edge 411 protruding relative to the edge of the first end 431 of the adhesive body 43 .

It can be seen from the foregoing description that the double-sided film of this creation includes release layers on both sides, and the two release layers at one end are cut evenly and the adhesive body is relatively inwardly shrunk, and one of the release layers at the other end is relative to the adhesive body and the adhesive body. The other release layer is protruding, so the user can separate it from the adhesive body and the other release layer by extending the protruding release layer. Since the adhesive body is still attached to the other release layer at this time, Therefore, when attaching the adhesive body, the user can hold another release layer to avoid contaminating the adhesive body and affecting its adhesion. After the adhesive body is attached, the remaining release layer is relatively relatively The main body is protruding, so that the user can peel off the release layer relative to the adhesive body through the protruding part, so that the other adhesive surface of the adhesive body is exposed and can be further attached to the attached object.

The present invention further provides an air-conditioning filter set, which includes a non-woven filter and the double-sided film in any of the above-mentioned embodiments. Of course, the double-sided film of this creation can also be used with other items that need to be attached, such as gift bags, etc., and has a wide range of use values. The double-sided film in this case can use a kiss cut process, but the process method is not a problem, and any production method that can produce the double-sided film at a cost can be applied to this case.
