ABSTRACT:
Packaging, particularly for medical supplies and devices, is made from spunbonded olefin sheet material. At least a portion of the olefin sheet material is deformed to increase its surface area by between 4 and 60 percent, so as to create a pocket of a dimension sufficient to envelope the medical supply or device. After the medical supply is placed within the pocket, it is covered and sealed by another sheet having microbial barrier characteristics. Even though deformed, the spunbonded olefin packaging possesses the ability to allow quick passage of sterilizing gas, yet is resistant to penetration by contaminating microorganisms.
