Hot melt adhesive compositions combining the characteristics of thermoplastic hot melt adhesives and reactive adhesives can be prepared by blending a polyester polyether thermoplastic elastomer having the formula ##STR1## wherein Nu is a predominately cyclic nucleus and R.sub.1 is randomly selected from either a C.sub.2-6 alkylene or an amorphous polyether subunit comprising a polyoxyalkylene group with a polyisocyanate prepolymer. The resulting composition is flexible and may be used as an adhesive or as a sealant.

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.
