Abstract
A package for containing sterile packed items is formed from the joining of a first sheet of material and a second sheet of material. The package formed comprises a cavity for containing at least one item, a first group of sealing elements and a second set of sealing elements. The two groups of sealing elements have relative size(s), shape(s) and placement(s) to provide a desired level of seal and mechanical cohesion while reducing fiber tear out that could contaminate the contained items.
