    • Provided herein is a method of manufacturing a polyolefin sheet using a circulating belt and a first roller, comprising the steps of: heating polyolefin resin to melt polyolefin; and forming the molten polyolefin into a polyolefin sheet using an extruding die, wherein the circulating belt includes a plurality of second rollers (cooling rollers) which come into contact with an inner side of the circulating belt and are arranged in a circle around the circulating belt running in a circle and which cool the rotating circulating belt; a temperature of the circulating belt is maintained at 0˜30 to cool the polyolefin sheet such that the polyolefin sheet has desired thickness, a temperature of the first roller is set to a specific temperature between 40 and 120, and the temperature of the first roller is maintained in a temperature range of the specific temperature ±5; and a linear speed of the molten polyolefin sheet is substantially equal to a rotation speed of the circulating belt or the first roller to obtain a polyolefin sheet having a thickness of 0.05˜0.45 mm and a width of 1100˜1700 mm The method is advantageous in that a wide-width polyolefin sheet having excellent flatness and a small thickness deviation can be manufactured.
    • 本发明提供使用循环带和第一辊制造聚烯烃片材的方法,包括以下步骤:加热聚烯烃树脂以熔化聚烯烃; 以及使用挤出模具将熔融聚烯烃形成聚烯烃片材,其中循环带包括与循环带的内侧接触并围绕循环带布置的多个第二辊(冷却辊) 以循环方式运行,并冷却旋转循环带; 循环带的温度保持在0〜30以冷却聚烯烃片材,使得聚烯烃片材具有期望的厚度,将第一辊子的温度设定在40至120的特定温度,并且第一辊子的温度 保持在特定温度±5℃的温度范围内; 熔融聚烯烃片材的线速度基本上等于循环带或第一辊的转速,得到厚度为0.05〜0.45mm,宽度为1100〜1700mm的聚烯烃片材。该方法有利于 可以制造具有优异的平坦度和小的厚度偏差的宽幅聚烯烃片材。
