Heat-treating method of a thermoplastic resin film |
| 摘要 |
<p>A thermoplastic resin film (17) is preheated as the temperature T is changed to at a temperature of Tg < T < m.p.-10 DEG C, and absolutely contacted with a belt (14) by being pressed at a linear pressure of 9.8N/cm -980.0N/cm (Tg: a glass transition temperature of the thermoplastic resin film, m.p.: a melting point of the thermoplastic resin film). Next, the thermoplastic resin film is heated as the temperature T is changed to at a temperature of m.p.-20 DEG C < T < m.p.+20 DEG C while being absolutely contacted with the belt, and successively, the thermoplastic resin film is cooled while being absolutely contacted with the belt, and then the thermoplastic resin film is peeled from the belt.</p> |
