发明名称 MULTI-LAYER LAMINATED RESIN FILM, AND METHOD AND APPARATUS FOR PRODUCING THE SAME
摘要 <p>A multi-layer laminated resin film comprising top and bottom outer laminates of sandwich structure each including a layer of reclaimed synthetic resin mixture entirely surrounded by a second fresh resin layer and an inner layer interposed between and secured to the inside surface of the top and bottom laminates, A process for producing a multi-layer laminated resin film using reclaimed resin mixture in which a first resin of reclaimed synthetic resin mixture is fed into a first composite die in a first direction, a second resin of fresh resin is fed into the first composite die in a second direction at right angles to the first direction to surround the first resin, adhesive is fed into a second composite die in a first direction and a third resin is fed into the second composite die in a second direction diametrically opposite to the first direction. A device for producing a multi-layer laminated film using reclaimed resin mixture which comprises a series of composite dies connected in end-to-end relationship in which each of the composite dies includes upper and lower die portions, and first, second and third extruder means associated therewith to feed different materials to the respective composite dies.</p>
