Abstract
A method of attaching first and second layers together using a sealing material which flows under heat and pressure is provided. The method involves applying heat and pressure to a laminate comprising the first layer, the second layer and the sealing material wherein a first portion of the second layer having one or more apertures is between the heat sealing material and the first layer. Under heat and pressure, the sealing material flows into and through the one or more apertures in the second layer and contacts the underlying first layer thereby forming a rivet which attaches the first and second layers together.
