The release material is connected with the back lining, and the unfolding area is large after the release material is peeled, namely the handheld area is large, so that the dressing can be conveniently operated by hands without touching the pasting surface of the dressing to cause poor pasting.

In order to solve the problem, the utility model adopts the following technical scheme:

an integrated transparent dressing comprising:

a backing layer;

the glue coating layer and the adhesive connecting layer are arranged on the back lining layer along the direction vertical to the back lining layer;

a plurality of release materials are arranged above the gluing layer;

the release material is provided with a folded edge;

the back lining layer is connected with the release material into a whole through the adhesive connecting layer.

Preferably, the adhesive connecting layer is located at both ends of the backing layer.

Preferably, the release material is divided into a first release material and a second release material, the edge of the first release material is connected with one side of the backing layer through an adhesive connecting layer, and the edge of the second release material is connected with the other side of the backing layer through an adhesive connecting layer.

Preferably, the release material is folded at one end away from the adhesive connecting layer.

Preferably, the total area of the plurality of pieces of release material after being folded is not smaller than the glue coating layer.

Preferably, the first release material and the second release material have the same area.

Preferably, the transparent dressing of integral type is handheld region, the back sheet of half-cut reservation, rubber coating, the back sheet of half-cut reservation and handheld region in proper order after the expansion.

Preferably, the width of the backing layer left by half-cutting is more than 3mm, so that the rubberized layer is staggered with the edge of the backing layer.

The utility model discloses a transparent dressing back sheet and glue film protection from type material are connected through transparent adhesive material. The width of the backing layer reserved by half-cutting is larger than 3mm, so that the gluing layer and the edge of the backing layer are staggered, the phenomenon that the backing layer and the gluing layer are adhered by an adhesive connecting layer in a neat edge manner is prevented, and the backing layer is peeled off to cause poor peeling of a tape film when the use is influenced

The utility model has the advantages that: the transparent dressing backing and the release material protected by the adhesive layer are integrated, and the waste material stripped off in use is one piece, so that the cleaning of a use site is facilitated; the holding area is large after the release material is unfolded, so that the adhesive tape is convenient to adhere and cannot touch the adhering surface by mistake.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following describes the integral transparent dressing in detail with reference to the attached drawings.

Example 1

Referring to fig. 1 and 2, the embodiment provides an integrated transparent dressing, which comprises a backing layer 1, a polyurethane film rubberized layer 2 arranged in a direction perpendicular to the backing layer 1, and an adhesive connecting layer 5 arranged at the edge of the backing layer 1; the first edge of leaving type material 3 is connected through adhesive linkage 5 with backing layer 1 one side, and the second is connected through adhesive linkage 5 from the edge of type material 4 and backing layer 1 opposite side, and first type material 3 has hem 6 from type material, and the second covers first type material 3 department from type material 4 to have the hem.

Referring to fig. 3, with the transparent dressing of integral type expansion back, first from type material 3 and second from type material 4 for handheld region, rubber coating 2 is for pasting the region, and rubber coating 2 both ends have the back sheet 7 of half-cut reservation, and handheld regional total area is not less than the area of pasting the region.
