Abstract

The present invention relates to a plastics laminated sheet comprising two or more sheets of non-stretched crystalline plastics, characterized in that at least one sheet is extruded, cooled by contact with a cooling roller 4 and the surface a thereof which has not contacted the cooling roller is bonded to another 2 of said sheets for laminating the one sheet with the other sheet. The surface a' of the one sheet to be bonded may itself be cooled by an air blower 7. <IMAGE>
