Abstract

The disclosed packaging bags may include a flexible front sidewall and a flexible rear sidewall with at least a first closed edge, second closed edge, and third closed edge coupling the front sidewall to the rear sidewall. A perforation may be formed through the flexible front sidewall and the flexible rear sidewall along the first closed edge. The perforation may extend in a first segment from the first closed edge toward a central region of the packaging bag, in a second segment in a direction along the first closed edge, and in a third segment back to the first closed edge. The second segment may include at least one elongated ventilation slit. Various other related packaging bags and methods are also disclosed.

First claim

What is claimed is:

1. A method of using a packaging bag, the method comprising:
storing a first item that has been sterilized with ethylene oxide in a packaging bag;
removing a removable portion of the packaging bag to access the first item, comprising:
separating the removable portion from the packaging bag along a first segment of a perforation that extends from a first closed edge toward a central region of the packaging bag;
separating the removable portion along a second segment of the perforation including along an elongated ventilation slit; and
separating the removable portion along a third segment of the perforation that extends from the second segment to the first closed edge;

leaving a first handle between the first closed edge and a second closed edge that is adjacent to the first closed edge;
leaving a second handle between the first closed edge and a third closed edge that is adjacent to the first closed edge and that is opposite the second closed edge; and
after removing the removable portion of the packaging bag, storing a different second item in the packaging bag.

2. The method of claim 1 , wherein at least a portion of the second segment of the perforation is parallel to the first closed edge.

3. The method of claim 1 , wherein:
the first handle has a width of at least about 1.5 inches between the second closed edge and the first segment of the perforation; and
the first handle has a width of at least about 1.5 inches between the third closed edge and the third segment of the perforation.

4. The method of claim 1 , wherein:
the first handle has a length of at least about 3 inches; and
the second handle has a length of at least about 3 inches.

5. The method of claim 1 , wherein:
the first segment of the perforation is curved; and
the third segment of the perforation is curved.

6. The method of claim 1 , wherein the elongated ventilation slit has a length of at least about 0.5 inch.

7. The method of claim 1 , wherein storing the different second item in the packaging bag comprises storing a refuse item in the packaging bag.

8. The method of claim 1 , wherein storing a first item that has been sterilized with ethylene oxide in the packaging bag comprises storing a medical item in the packaging bag.

9. The method of claim 8 , wherein storing the different second item in the packaging bag comprises storing a second item that the first item replaces.
