- the present invention relates to an absorbent article to be packaged, in which an adhesive material for adhering the main body to clothing is disposed on a part of the main body, and is individually packaged by a protective sheet.
- Absorbent articles such as sanitary napkins are widely used in the form of being individually packaged and sold. Some of such absorbent articles are coated with an adhesive material that is applied to the wearer's clothing, and therefore when the absorbent article is individually packaged, the adhesive material is attached to the packaging material. It is necessary to prevent this.
- a method of individually packaging an absorbent article using a protective sheet for protecting an adhesive material is known (see, for example, Patent Document 1). In this absorbent article, the protective sheet also serves as a packaging for the absorbent article.
- the surface of the protective sheet is treated so that it can be peeled without reducing the adhesive strength of the adhesive.
- the protective sheet has a pressure-sensitive adhesive tape provided on a part to which the pressure-sensitive adhesive is applied or an end of the protective sheet, and the pressure-sensitive adhesive material (or pressure-sensitive adhesive tape) is in a state where the absorbent article is folded. Affixed to a part of Thereby, the absorbent article is packaged using the protective sheet.
- the conventional absorbent article described above has the following problems. That is, the adhesive material of the adhesive tape may permeate the adhesive material applied to the absorbent article through the protective sheet due to changes over time, temperature changes, and the like. In this case, the adhesive materials are compatible with each other, and an adhesive force higher than expected is generated. Therefore, it is difficult to open the absorbent article, or the protective sheet is damaged at the time of opening, making it difficult to remove the protective sheet from the absorbent article. There was something to do.
