| | Adhesive bandage backings - United States Patent 3,973,563 |
 | | Thus, for example, when an adhesive bandage is applied to flexural joints such as fingers, elbows or knees, which are subjected to extensive stretching and, to a lesser degree, constriction and other distortion during normal activities, the bandage will easily stretch with the skin and substantially follow the changing contours of the skin. |
 | | For this reason, it is important that adhesive bandages be made of relatively thin materials with sufficient tensile strength to provide for the integrity of the bandage while still maintaining a low surface friction to minimize rub-off or abrasion by objects contacting the adhesive bandages in use, such as, for example, clothes. |
 | | The adhesive which is coated to portions of the backing may be any conventional porus pressure sensitive adhesive used in the preparation of such adhesive bandages, surgical dressings and the like, the particular type per se not being part of the present invention. |
