Patent film production line/machine Cross-laminated film machine 1)New technology 2)Much stronger than normal tarpaulin 3)Patented technic Cross-laminated film machine Cross laminated multilayer film machine Other name: XF film machine, XF tarpaulin making machine Machine details: 1)First step: The co-extruded film is blown from a three-ply resin structure, keeping the molecular orientation in the direction of machine operations. 2)Second step: The film bubble is cut at a specific angle by a spiral-cutting machine. Now the molecular orientation of the cut film is cross to the machine direction with a specific angle. 3)Third step: Multi-layers of the spiral cut films, with orientations at opposite angles, are laminated together. 4)Fourth step: The cross-laminated film has to go through a stretching process in different directions, so the molecules of the final products are isotropically oriented. This process highly enhances the strength
