  • Process for making perforations in a plastic film material
    Patent number: 9187195
    Abstract: A process for making perforations in a plastic film material to be used in a package for products prone to decay, in which the surface area of the perforations made in a defined surface area of the plastic film material must have a predetermined value, which process has the following steps: A. making of one perforation or a number of perforations in the defined surface area of the plastic film material, B. measuring the surface area of the perforation or of the number of perforations made in step A, C. calculating the difference between the predetermined perforation value minus the surface area of all perforations present in the defined surface area, D. if the difference is smaller than a first predetermined reference value, stopping the making of perforations in the defined surface area of the plastic film material, or if the difference is larger than the first predetermined reference value repeating the steps A to C until the difference is at most equal to the first predetermined reference value.
