  • Patent number: 3941246
    Abstract: A belt-forming package, intended for use in packaging radiographic dental films is presented. The package is characterized in that the film materials are separately packed in such a way that taking one film packet out of the belt is facilitated by the provision of zones of less mechanical strength at the circumference of each separate packet. Opening of the separate packets puts no problems as a lip-like portion having an asymmetric wave-type form is overlappingly sealed to another portion so that the rupturing of the seal between both portions, causing the opening of the concerning separate packet is facilitated.
