  • Patent number: 4781297
    Abstract: A package for sterile articles, comprising a paper part and a plastic part connected to the paper part along longitudinal and transverse lines. The plastic part comprises a linearly oriented plastic film material which can be torn in its direction of orientation. This direction of orientation is parallel to those longitudinal lines, and tear indications on the plastic part at one end of the package are parallel to and disposed between but closely adjacent those longitudinal lines. The paper part has edge portions that are folded over toward each other. The longitudinal lines secure the plastic part to the outer sides of those folded-over portions, said folded-over portions having free edges that are between and spaced a substantially distance from the tear indications. There is a sterile article in the package, those edge portions being folded over the edges of the sterile article.
