  • Package, for example, for surgical instruments and products
    Patent number: 4630729
    Abstract: The package consists of a strip of plastics foil or sheeting and a strip of paper, whereby the two strips are sealed together at their margins, so as to permit opening by a peeling action. The seal consists of two groups of sealing elements. The sealing elements of group 1 are of small dimensions and ensure "sealability", while the sealing elements of group 2 are linear having a restricted width and which are arranged such that they run transversely to the direction of peel. The arrangement combines a high degree of mechanical strength with ease of peeling during which the tearing-out of fibres from the packaging is minimized.
