  • Patent number: 7846523
    Abstract: A medical laminated body with a releasing member, has a medical sticking member having a sequentially laminated base material and a pressure-sensitive adhesive layer. It further has a releasing member laminated on a side of the medical sticking member that is provided with the pressure-sensitive adhesive layer, and a repositionable pressure-sensitive adhesive layer formed as a part of the releasing member at a side of the releasing member distal from the medical sticking member. A ratio represented by A2/A1 is in a range of 8 to 100 where Al is an adhesion of the repositionable pressure-sensitive adhesive layer in accordance with JIS-Z-0237 and A2 is an adhesion of the pressure-sensitive adhesive layer in accordance with JIS-Z-0237. Al is in the range of 10 to 150 g/25 mm, and A2 is in the range of 250 to 1,000 g/25 mm.

  • Publication number: 20080131642
    Abstract: The present invention provides a laminated body with a releasing member and a method for manufacturing the same. According to the laminated body with a releasing member, a sticking member and a releasing member can be easily peeled off with one hand, and even if a plurality of such laminated body with a releasing member are packaged by stacking them as they are, the laminated body can be peeled off from one another and used as individual laminated body with a releasing member. Disclosed is a laminated body with a releasing member, which includes a sticking member constituted by sequentially laminating a base material and a pressure-sensitive adhesive layer, a releasing member being laminated on the side of the sticking member that is provided with the pressure-sensitive adhesive layer, and a repositionable pressure-sensitive adhesive layer being formed as a part of the releasing member at the backside of the releasing member, wherein a ratio represented by A2/A1 is in the range of 1.
