<p>A flexible container for the packaging of products having a pressure sensitive adhesive (92) thereon, such as sanitary napkins. The container is formed of paper or plastic film (16) coated on one side with a layer of silicone, the container construction being such that the silicone coating defines the interior surfaces of the container. Due to the nonstick characteristic of the silicone coating, the usual protective liner for the adhesive on the packaged product can be omitted. The side seams of the container are formed by the application of heat or ultrasonic energy in combination with mechanical deformation of the paper or film to produce embossments (18) in the seam areas. The side seams may comprise two or three layers of material. The nature of the side seams may be such that the container may be opened by peeling apart the seams, or the seams may be sealed so tightly that the container can be opened only by tearing the material.</p> |
