RELEASING LAMINATED SHEET AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a releasing laminated sheet not having a defect of gradually raising an interface adhesive strength with time from a manufacturing time and not under going change of interface adhesive strength with the elapse of time by gradually advancing curing of a thermoplastic resin and a method for manufacturing the same. SOLUTION: In the releasing laminated sheet comprising a thermoplastic resin layer, the thermoplastic resin contains a heat resistance surfactant of a range of 0.1 to 1 wt.%. The method for manufacturing the releasing laminated sheet comprises the step of manufacturing the sheet at a temperature in the case of extrusion laminating as a resin temperature of a T-die outlet of 280 to 320 deg.C.
