ABSTRACT:
A method is disclosed for making containers (40) in which a sheet of thermoplastic material (10) that is adapted to be formed into a pouch is introduced into a mold cavity (14). A molding compound (22) is also introduced into the mold cavity (14). The molding compound (22) is permitted to be bonded with the thermoplastic sheet (10) inside the mold cavity (14) to form a container port (20) in situ. The thermoplastic sheet (10) and bonded molding compound (22) are removed from the mold cavity (14) and the sheet carrying the port (20) formed from the bonded molding compound is folded and cut to form a container (40).
