Open the CIPO recordAbstract From the Canadian patent
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", whilst 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 each of peeling during the tearing-out of fibres from the packaging is minimized.
