Abstract

The invention relates to a method for sealing a peripheral attachment member onto a sealed pouch that has been previously filled with a product. The invention also relates to a pouch that includes a peripheral attachment member sealingly attached to at least one of its faces. The method includes a step of providing a multi-layer pouch that is configured so as to provide an inner sealant adapted to form a closed enclosure along sealing lines and an outer sealant that forms at least one external face of the pouch wherein the outer sealant has a melting point that is lower than the melting point of the inner sealant.
