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 (30) are provided which may be stored in a folded configuration prior to use. Means of attachment (40; 42; 45; 46) and means of release (50, 55, 57) are created on the garment facing side (20) of the article. The manner in which the product is folded and the patterns in which the attachment and release means are arranged results in a product which does not require release paper and which securely fastens the products' transverse ends to the undergarment when the product is used. Other embodiments using barrier films affixed to the garment facing side of the article are also disclosed. Methods of making and packaging the articles disclosed are also provided.
