PROBLEM TO BE SOLVED: To provide a method for producing a film for dental impression, for use in combined impression in which two types of dental impression materials different from each other in material are combined.SOLUTION: On both sides of a resin film, resin nonwoven fabrics are stacked to form three layers and virgin pulp is stacked and laid below the resin nonwoven fabrics positioned in the lowermost layer. Then, they are wound up around a roll to be formed into a roll form as a whole, and heated by a heating means at a prescribed temperature, and the resin nonwoven fabrics is heat bonded onto both sides of the resin film.COPYRIGHT: (C)2009,JPO&INPIT【課題】材質の異なる2種の歯科用印象材料を重ね合わせる連合印象に用いる歯科印象用フィルムを製造する方法を提供する。【解決手段】樹脂製フィルムの両面にそれぞれ樹脂製不織布を重ね合わせて3層に形成し、最下層に位置する前記樹脂製不織布の下側にバージンパルプを重ねて敷いた後、それらをロールに巻きつけて全体をロール状に形成し、次いで加熱手段により所定温度で加熱して前記樹脂製フィルムの両面に前記樹脂製不織布を熱接着させる。【選択図】なし
