Abstract

The present invention provides a novel packaging material for sterilization which has processing suitability as a packaging material, is compatible with all sterilization processing methods such as those performed under high-temperature conditions, has small variation in shapes and dimensions, and is capable of maintaining an internal sterilized condition. This packaging material for sterilization is configured from at least two layers of laminated non-woven fabrics comprising a non-woven fabric layer (I) formed of continuous long fibers having an average fiber diameter of 5-30 μm and a non-woven fabric layer (II) formed of ultra-fine fibers having an average fiber diameter of 0.1-4 μm.
