Abstract
A method of manufacturing at least one sample pouch from a film of flexible, heat-sealable material begins with providing a film of flexible, heat-sealing material with two opposing edges. Next, arrange the opposing edges on top of one another so as to form a body with a generally tubular wall. Next, heat-seal the opposing edges to form a longitudinal sealing area between the two ends of the body. Then, transversally heat-seal the wall of the body to form at least one transversal sealing area with a general rigidity. Then, fill the pouch with product and cut a shape in at least one transversal sealing area. The cut-out is made at a distance from the inner edge of the transversal sealing area. The cut-out has at least one part that is generally tiled in relation to the longitudinal and transversal directions of the pouch in order to guarantee the seal of the body while shaping the transversal sealing area in a given way.
