Abstract
The present invention relates to an assembly including a pouch, a product filled in the pouch, and a fitment that is applied to the pouch through the method of ultrasonic sealing. The pouch may be produced without any fitment or opening device and completely sealed after the filling. The fitment may be applied through the method of ultrasonic sealing after the filling and sealing of the pouch. The pouch may include a film material specially treated on the inside surface through the addition of a special lacquer or film layer to avoid a sealing at this position. The fitment includes one or more of any thermoplastic polymer, or a special blended polymer, such as metallocene.
