LAMINATE FILM USING POLYLACTIC ACID-BASED RESIN |
摘要 |
Our invention is a laminate film comprising a water-soluble resin layer and a polylactic acid-based resin layer laminated on at least one side of a substrate film, the water-soluble resin layer has a thickness of 0.1 to 15 μm, the polylactic acid-based resin layer has a thickness of 10 to 500 nm. Such a configuration provides a laminate film of which the water-soluble resin layer and the polylactic acid-based resin layer are easily separated from the substrate film and which is excellent in coating ability, adherence and followability to a soft and curved adherend, as well as compatibility to skin and organs such as viscera, so as to be suitable for wound dressing, adhesion prevention material and a skin external agent such as skin-care product. |
