摘要： A method for forming a film of plastic material includes urging molten resin through a die head opening to form a stalk having an extrusion profiled rail of resin material extending radially outward from a tubular wall, the die head opening including an annular orifice that defines a thickness of the tubular wall and a cross-sectional shape of the rail; cutting the rail to form discrete elements while leaving the tubular wall un-punctured; and inflating the stalk with a gas bubble maintained within an interior space of the tubular wall to form a thin film tube.
