Problems solved by technology

However, since there is no research on the paste, there is no research on the porosity of the elastic film, the open area per pore, the paste retention and water retention when using a water-based paste, and the sublimation of the drug. There is a problem with the persistence of the drug effect

Embodiment 1

[0099] As the non-woven fabric layer A, Idemitsu Unitech Co., Ltd. made UN5050 (spun-bonded non-woven fabric using olefin-based elastomer resin, weight per unit area: 50 g / m 2 , thickness 0.3mm, fineness 5dtex) is laminated with a film with a thickness of 20 μm of MORETEC 0218CN (ethylene-1-octene copolymer) manufactured by Prime Polymer Co., Ltd. Needle processing to give each through hole an area of ​​0.05mm 2 , through holes with a porosity of 1.4% to maintain the shape of the hole, and then, as the non-woven fabric layer B, UN5040R (spun-bonded non-woven fabric using olefin-based elastomer resin, unit area Weight 45g / m 2 , thickness 0.25mm), on the elastomer film surface of the non-woven fabric layer A / elastomer film laminate processed through the through hole, use the spray method according to 5g / m 2 Adhesive is supplied, and nonwoven fabric B is laminated and bonded by a conventional method to obtain a weight per unit area of ​​105 g / m 2 , thickness 0.4mm, 50% tensile...

Embodiment 2

[0103] The area of ​​each through-hole of the elastomer film of Example 1 was set to 0.17mm 2 , The same support as in Example 1 was obtained except that the porosity was set to 1.4%. The resulting support has a weight per unit area of ​​105 g / m 2 , thickness 0.4mm, 50% tensile recovery rate 91%, moisture permeability 5300g / m 2 • 24-hour support.

[0104] Table 1 shows the performance of the obtained support and the evaluation results when it was made into a patch.

[0105] The patch using the support of Example 2 has excellent elasticity and plaster retention, has a good application feeling without sticky feeling, is also excellent in water retention, and suppresses the sublimation of the drug to improve the durability of the drug effect Patches for water-based ointments.

Embodiment 3

[0107] U-shaped 30 g / m made by Idemitsu Unitech Co., Ltd. as the non-woven fabric layer A 2 (Spun-bonded non-woven fabric using olefin-based elastomer resin, basis weight 30g / m 2 , thickness 0.2mm, fineness 5dtex) is laminated with a 15μm film of MORETEC 0218CN (ethylene-1-octene copolymer) manufactured by Prime Polymer Co., Ltd., and hot needle processing is performed from the elastomer film side with a needle diameter 0.7mm , thus giving each through-hole an area of ​​0.05mm 2 , A through-hole with an opening ratio of 1.4% to maintain the shape of the hole, and then, as the non-woven fabric layer B, U-shaped 30g / m made by Idemitsu Unitech Co., Ltd. 2 (Spun-bonded non-woven fabric using olefin-based elastomer resin, basis weight 30g / m 2 , thickness 0.2mm), on the elastomer film surface of the non-woven fabric layer A / elastomer film laminate processed through the through hole, spray at 4g / m 2 An adhesive is supplied, and the nonwoven fabric layer B is stacked and bonded by ...

Abstract

Disclosed is a patch support for a water-based plaster having the following structure, said patch support having excellent plaster-holding properties and excellent water-holding properties, inhibiting the sublimation of a drug to improve the long-lasting drug effect, imparting neither restricted feeling nor roughness to a wearer due to the thinness and good flexibility thereof, and having controlled moisture-permeability and little stickiness to thereby comfort the wearer. The patch support for a water-based plaster is a laminate consisting of three layers laminated together, i.e., a non-woven fabric layer (A), a non-woven fabric layer (B) and a film layer having through holes, said film layer being positioned between the non-woven fabric layers (A) and (B), wherein said film layer is formed of a resin comprising an olefin-based elastomer, and said through holes have an area of 0.02-0.18 mm2 per hole and a porosity of 1-10%.

Description

technical field [0001] The present invention relates to an adhesive support for aqueous plasters having excellent properties. More specifically, the present invention provides a water-based product that is excellent in paste retention and water retention, suppresses the sublimation of the drug in the paste to improve the durability of the drug effect, has excellent stretchability, does not feel sticky, is thin, and has a good application feeling. Sticking support for paste. Background technique [0002] Patent Document 1 describes a patch in which a nonwoven fabric is laminated on at least one side surface of a synthetic resin film having microporosity and a moisture-containing adhesive layer is laminated on the film side of a support. However, in this patch, the stretchability of the synthetic resin film and the nonwoven fabric is insufficient, and there is a problem with the feeling of application. [0003] Patent Document 2 describes an elastic film composed of a compos...
