Abstract

Abstract Absorbent articles (10) such as panty liners, thin full-sized sanitary napkins and the like having a garment facing side (20) and a body facing side are provided which may be stored in a folded configuration prior to use. Means of attachment (30) and means of release (40), most preferably silicone, are created on the garment facing side (20) of the article. The patterns in which the attachment and release means (30, 40) are chosen such that when the article is folded, the adhesive means (30) contact the release means (40), eliminating the need for release paper, but allowing the article to be unfolded and used. Other embodiments using barrier films affixed to the garment facing side of the article are also disclosed. The barrier films are used in place of an outer wrapper member to protect the body-facing side of the napkins from being soiled prior to use. Methods of making and packaging the articles disclosed are also provided.
