摘要： 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.

摘要： The present invention relates to a polyolefin composition for an interior sheet/film. The polyolefin composition of the present invention for an interior sheet comprises 70 to 99 wt % of polyolefin and 1 to 30 wt % of modified polyethylene terephthalate having a melting point of 130 to 180° C. The polyolefin composition of the present invention is environmentally friendly and has good physical properties such as workability, printing characteristics, and adhesiveness. In addition, sheets having various thicknesses can be produced by extrusion without having to stretch the sheets, and thus the sheets can be used separately or in combination in various application fields.
