A sterilization wrap is provided. The sterilization wrap includes a first sheet that is configured for providing a barrier to prevent at least some bacteria from passing therethrough while allowing sterilization gas to pass therethrough. A second sheet is attached to the first sheet. The second sheet is located on the first sheet so that a perimeter of the second sheet is contained entirely within a perimeter of the first sheet.

Sterilization wrap with additional strength sheet

The present invention provides a nonwoven web prepared from an aliphatic polyester polymer which has sufficient tear strength and is biodegradable. Biodegradable nonwoven webs of the present are prepared from a polymer blend having from about 65% by weight to about 99% by weight of a biodegradable aliphatic polyester polymer and from about 1% by weight to about 35% by weight of a second polymer selected from the group consisting of a polymer having a lower melting point than the biodegradable aliphatic polyester polymer, a polymer having a lower molecular weight than the biodegradable aliphatic polyester polymer and mixtures thereof. Surprisingly, the nonwoven webs of the present invention have a tear strength greater than the tear strength of a nonwoven web prepared from the biodegradable aliphatic polyester polymer alone. In addition, other properties of the resulting nonwoven web, such as the tensile strength and energy to break, are not adversely affected, by the addition of the second polymer, in ways that make the resulting nonwoven web unusable for its intended purpose.

High strength nonwoven web from a biodegradable aliphatic polyester

A composition including an aromatic polyester and a copolyester having a lower melting point than the aromatic polyester. The aromatic polyester and the copolyester can be blended together to form fibers and fibrous webs. The composition can be thermally bonded at a temperature below the melting point of the aromatic polyester.
