Title:
構造化した表面を備える、ポリ乳酸ポリマー系フィルム及び物品
Document Type and Number:
Japanese Patent JP6979407
Kind Code:
B2
Abstract:
Presently described are polylactic acid polymer based films comprising a structured surface and articles. In one embodiment, the film comprises a semicrystalline polylactic acid polymer; a second polymer such as polyvinyl acetate polymer having a glass transition temperature (Tg) of at least 25° C.; and plasticizer. Articles are also described such as a tape or sheet, comprising the structured PLA-based film and a layer of (e.g. pressure sensitive) adhesive disposed on the film. In some embodiments, the tape or sheet further comprises a low adhesion backsize or a release liner. The article can be suitable for various end-uses. In one embodiment, the tape is a paint masking tape. In another embodiment, the tape is a floor marking tape.
