Abstract
A method for manufacturing pouches made of at least partly thermoplastic material, including the steps of superimposing at least two webs of at least partly thermoplastic material, joining the webs at adhesion regions or lines, and cutting the webs at cutting regions or lines in order to provide pouches. In a condition in which the webs are superimposed, the method further includes the step of mutually aligning the webs by causing the elongation of at least one of the two webs via the application of heat.
