Embodiment 1

[0040] The underlying backing material was prepared by coextrusion.

[0041] Backing 1: First polymer outer layer - a blend of 50% by weight low density polyethylene (CHEVRON PHILLIPS LDPE 1017 coating resin) and 50% by weight linear low density polyethylene (Dowlex 2517 by Dow CHEMICAL). Elastomeric polymer inner layer - a blend of 58% by weight metallocene catalyzed ultra-low density polyethylene copolymer (AFFINITY® PL 1280 from DOWCHEMICAL) and 42% by weight ethylene methyl acrylate copolymer (TC 120 from EXXONCHEMICAL COMPANY); second Polymer outer layer - a blend of 50% by weight low density polyethylene (CHEVRON PHILLIPS LDPE 1017 coating resin) and 50% by weight linear low density polyethylene (Dowlex 2517 by DowCHEMICAL). Backing material 1 has a basis weight of 70g / m 2 . The comonomer in the above metallocene catalyzed ultra low density polyethylene copolymer is octene.

[0042] Backing 2: First polymer outer layer - a blend of 50% by weight low density polyethyle...

Abstract

The viscose bandage includes lining material, adhesive applied to the lining material and protecting pad applied onto the adhesive and contacting the wound. The lining material includes the first layer containing thermoplastic polymer, the inner layer connecting elastic polymer and the second layer containing thermoplastic polymer.

Description

field of invention [0001] The present invention relates to an adhesive bandage for application on skin wounds, irritations, abrasions, bruises, etc., and more particularly, the present invention relates to an adhesive bandage comprising an improved backing material. The backing material is a flexible polymer film consisting of two outer layers of non-elastic polymer and an inner layer of elastic polymer. Background technique [0002] Adhesive bandages have been marketed for many years to aid in the healing and / or protection of cuts, bruises, scrapes, and similar skin wounds. These bandages cover and protect the wound allowing it to heal. Such bandages include a backing material having an adhesive coated on one major surface. Wound-contact pads are used to cover a wound and are secured to the adhesive-coated surface of the backing (usually, but not always, in the central region of the backing) by a portion of the adhesive composition. In use, the remainder of the adhesive ...
