Air-permeable tipping paper

[0026] Example, see Figure 1 to Figure 3 Shown: breathable tipping paper, including: inner layer 10, interlayer 20, outer layer 30, adjusting strip 40 and so on.

[0027] Specifically, the inner layer 10 is provided with a plurality of inner through holes 11, and the inner layer 10 is made of tipping base paper. The interlayer 20 includes dense strips 21 on the left and right sides, and an air permeable layer 22 between the two dense strips 21. The dense strip 21 is made of tipping base paper, and the air permeable layer 22 is made of sponge. The outer layer 30 is provided with a plurality of outer through holes 31, and the outer layer 30 is made of tipping base paper. Obviously, the interlayer 20 is sandwiched between the inner layer 10 and the outer layer 30. There are at least two adjustment bars 40, and the adjustment bars 40 are made by coating a glue layer on the tipping base paper. That is, the adjustment strip 40 has poor air permeability. At the same time, the two sides of the two dense strips 21 are respectively pasted on the inner layer 10 and the outer layer 30; any one of the inner through holes 11 and any one of the outer through holes 31 are not opposite to each other; the adjustment bar 40 is glued Pasted on the outer surface of the outer layer 30. A preferred way is that the extension direction of the adjustment strip 40 is along the circumferential direction of the filter tip of the cigarette made of the breathable tipping paper. In this way, the inner through hole 11 and the outer through hole 31 are not relatively straight, so that the filter tip made of the tipping paper has a better ventilation effect and is easy to adjust. At the same time, only need to tear off the different number of adjustment strips 40 to expose the different number of outer vent holes 31, and then adjust the degree of ventilation

[0028] Furthermore, at least two stamp holes 32 are provided on the outer layer 30. Obviously, each stamp hole 32 extends along the circumferential direction of the filter tip of the cigarette made of the breathable tipping paper. In this way, after all the adjustment strips 40 are torn off, part of the outer layer 30 can also be torn off through the stamp hole 32 to increase the degree of air permeability.

[0029] Furthermore, the widths of the adjustment bars 40 are different. In this way, different adjustment strips 40 can be torn off to obtain different adjustment effects.

[0030] The above are only the preferred embodiments of the present invention, and do not limit the scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the description and drawings of the present invention, or directly or indirectly applied to other related The technical field is similarly included in the scope of patent protection of the present invention.
