Abstract:
1. A method of sterilizing a product in a package to reduce tensile strength loss of the product after sterilization by radiation, comprising the steps of providing a package comprising a layer having an oxygen transmission rate equal to or less than about 0.2 cubic centimeter of oxygen per 100 inches squared per 24 hours, and having an interior, placing a product in the interior of the package, creating a vacuum in the package containing the product to a pressure equal to or less than about 100 millibars, thereby forming a vacuum packaged product, and sterilizing the vacuum packaged product with radiation, thereby forming a sterilized package containing the product, wherein the product, when removed from the sterilized package, has a reduction in its tensile strength less than about 20% where the reduction in tensile strength is measured by the following equation:
