摘要：: In the manufacture of single-use disposable packages or cartons for, for example, milk or juice, a web or sheet-formed packaging material is normally reformed by folding and sealing processes into individual packages. The material may possibly also be caused to pass through a bath of chemical sterilization agent. As a result of the forming and sterilization processes, it is impossible to provide the material beforehand with applied opening arrangements such as plastic pull-rings or the like. A method of connecting a gripping device (6) to sheet or web-formed packaging material essentially comprises a first application and liquid-tight sealing of an anchorage device (4) in a hole (3) in the material, the anchorage device (4), after reforming of the material into packages, being utilised as an anchorage point for a gripping device (6) in the form of a pull-ring or the like which, for example, may constitute a part of a prepared opening arrangement.
