保護シートの製造方法である。 That is, the present invention involves melt extrusion coating polyethylene on the surface of a long base sheet having a matte surface that is continuously transported, and pressing the polyethylene surface with a roll having a matte surface to obtain a laminated sheet. , a first step of peeling off the base sheet from the laminated sheet to obtain an unstretched double-sided matte polyethylene film, and separating the double-sided matte polyethylene film and a release paper having an adhesive layer on a part of the surface with the adhesive. This method of manufacturing a surgical protective sheet is characterized by comprising a second step of laminating layers to obtain an adhesive sheet, and a third step of cutting the adhesive sheet into a desired shape.

い。 The base sheet used in the first step may be a flexible sheet that is releasable to the polyethylene to be coated and has at least a matte coated surface, and is usually a synthetic resin film such as polyester or polypropylene, or paper. used.
Further, as the polyethylene, low density polyethylene is particularly suitable, and the coating thickness thereof is preferably 15 to 60 μm. If the coating thickness is less than 15μ, the manufacturing conditions will be difficult and the film will elongate when peeled from the base sheet, making it impossible to obtain a good film.If it is more than 60μ, the flexibility of the film will decrease and it will be economically disadvantageous. This is undesirable.
なお、低密度ポリエチレンの溶融押出し温度は
280℃以下の通常の押出しラミネートに比較して
低温にする方が、基材シートとの剥離を容易にで
きるので好ましい。 Furthermore, the melt extrusion temperature of low density polyethylene is
It is preferable to use a lower temperature than the usual extrusion laminate, which is 280° C. or lower, because it can be easily separated from the base sheet.
