Method of forming high-strength plastic film in one piece comprises the steps of: (1) pouring melted plastic material on a cylinder mold which has net type grooves on its surface through the groove hole of a feeder and dispersing plastic material on the top of cylinder mold; (2) rotating the cylinder mold with predetermined speed so that plastic material is transported to a pressing cylinder which is adjacent to the cylinder mold; (3) rotating the pressing cylinder to press plastic material in the net type grooves of the cylinder mold to form an even layer of plastic gel on the surface of the cylinder mold; (4) cooling and solidifying plastic material and plastic gel layer and removing plastics from the cylinder mold to form film with solid reinfoced net; (5) drawing the film longitudinally and transversely with a stretching machine to improve the extension strength of the film.
