Abstract: The present invention relates to a method for producing a multi-function polyester film by monolayer extrusion or multilayer extrusion, comprising providing at least one polyester material and at least one polyester material having diffusion particles; melt extruding and then cooling the polyester material rapidly to form a polyester sheet; treating the polyester sheet with biaxially orientation and then cooling the polyester sheet to obtain the polyester film. The method of the present invention provides the multi-function polyester film with a haze value below 95%, and a surface roughness value (Ra) above 0.1 nm.

Abstract: A container made from a synthetic resin, in particular, polyethylene terephthlate. The resin, after having been dried, is first injection molded into a preform like a test tube, and then softened by heating, and finally the required container is made by using the blow drawing technique in combination with a mold designed according the present invention for integrally blow molding containers having a radial base reinforcement structure. Said base reinforcement structure of the container comprises radially arranged enlarged feet, webs, and ribs, and a hub.
