[0006] The sanitary napkin body is provided with a first fold and a second fold at positions 2 / 5 and 4 / 5 away from the left end along the length direction. The left end of the sanitary napkin body is folded along the first fold and covers the upper side of the sanitary napkin body to form a two-layer structure. The right end of the sanitary napkin body is folded along the second fold and covers the uppermost side of the sanitary napkin body to form a three-layer structure.

[0007] The overlapping area is located at the position of the two-layer structure of the folded body.

[0008] The width of the overlapping area is at least 5 mm.

[0009] The beneficial effects of the utility model are as follows: the two ends of the sanitary napkin body along the length direction are folded in sequence to form a folded body with three layers, a polyvinyl alcohol film for covering the folded body is arranged outside the folded body, the two ends of the polyvinyl alcohol film along the length direction are located in the middle part of the front side of the folded body and overlap to form an overlapping area, the two ends of the polyvinyl alcohol film along the width direction are hot pressed and bonded to form a heat sealing area, a plurality of arranged hot pressing points are arranged on the heat sealing area, and a water-soluble and degradable polyvinyl alcohol film is used as the coating, which is both water-soluble and biodegradable, can reduce carbon emissions, and has a positive impact on environmental friendliness.

[0013] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0014] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0015] Some embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0016] Reference Figure 1-2 A sanitary napkin with a degradable coating comprises a sanitary napkin body, wherein the sanitary napkin body comprises a surface layer, an absorbent core, a bottom film, an adhesive backing and a release paper from top to bottom, the two ends of the sanitary napkin body along the length direction are folded in sequence to form a folding body 1 with three layers, a polyvinyl alcohol film 2 for covering the folding body is arranged outside the folding body, the two ends of the polyvinyl alcohol film 2 along the length direction are located in the middle part of the front side of the folding body 1 and overlap to form an overlapping area 3, the two ends of the polyvinyl alcohol film 2 along the width direction are hot pressed and bonded to form a heat sealing area 4, and a plurality of arranged hot pressing points 5 are arranged on the heat sealing area 4. The water-soluble and degradable polyvinyl alcohol film 2 is used as the coating, which is both water-soluble and biodegradable, can reduce carbon emissions, and has a positive impact on environmental friendliness.

[0017] The sanitary napkin body is provided with a first fold and a second fold at positions 2 / 5 and 4 / 5 away from the left end along the length direction, and the left end of the sanitary napkin body is folded along the first fold to cover the upper side of the sanitary napkin body, forming a two-layer structure (such as Figure 1 As shown in A in FIG. 1 ), the right end of the sanitary napkin body is folded along the second fold line to cover the uppermost side of the sanitary napkin body, forming a three-layer structure (as shown in FIG. Figure 1 As shown in B in the figure, that is, the uppermost end of the folded body 1 is located at the center of the folded body 1, which can make the folded body 1 as a whole have a symmetrical structure, can bring a visual balance, give people a sense of stability and harmony, and to a certain extent can soothe the irritability of women during menstruation.

[0018] The overlapping area 3 is located at the position of the two-layer structure of the folding body 1, so that the three-layer structure plus the polyvinyl alcohol film 2 can form a five-layer structure, and the two-layer structure plus the overlapping area 3 can also form a five-layer structure, which can make the overall thickness of the product as uniform as possible.

[0019] The width of the overlapping area 3 is at least 5 mm, which can effectively prevent external dust from entering the inside of the sanitary napkin through this area and causing pollution to the sanitary napkin.
