Title (EN) WATER-SOLUBLE FILM AND DRUG PACKAGING BODY
(FR) FILM SOLUBLE DANS L’EAU, ET EMBALLAGE POUR MÉDICAMENT
(JA) 水溶性フィルム及び薬剤包装体
Abstract:
(EN) Provided is a water-soluble film that, in addition to having excellent mechanical properties such as high tensile strength and high tensile elongation, does not bleed out prior to packaging body formation and contains a polyvinyl alcohol-based resin (A) and a plasticizer (B). The plasticizer (B) contains: a polyhydric alcohol (b1) having a melting point greater than 50°C and no more than 100°C; a polyhydric alcohol (b2) having a melting point of no more than 50°C; and a polyhydric alcohol (b3) having a melting point greater than 100°C.
(FR) L’invention concerne un film soluble dans l’eau qui non seulement présente d’excellentes caractéristiques mécaniques telles qu’une résistance élevée à la traction ou un allongement élevé à la traction, mais qui ne présente aucun risque de d’exsudation avant formation d’emballage. L’invention fournit un film soluble dans l’eau qui comprend une résine à base d’alcool polyvinylique (A) et un plastifiant (B). Ledit plastifiant (B) comprend un alcool polyvalent (b1) de point de fusion supérieur à 50°C et inférieur ou égal à 100°C, un alcool polyvalent (b2) de point de fusion inférieur ou égal à 50°C, et un alcool polyvalent (b3) de point de fusion supérieur à 100°C.
(JA) 水溶性フィルムの引張強度が高く、引張伸度が高いといった機械特性に優れるうえ、包装体形成前にブリードアウトが生じない水溶性フィルムとして、ポリビニルアルコール系樹脂(A)及び可塑剤(B)を含有し、上記可塑剤(B)が、融点が50℃より大きく100℃以下の多価アルコール(b1)、融点が50℃以下である多価アルコール(b2)及び融点が100℃より大きい多価アルコール(b3)を含有する水溶性フィルムを提供する。
