| titleOfInvention | Sandwich packaging belt and production method thereof |
| abstract | A sandwich packaging belt comprises a polypropylene (PP) surface coating layer and a core coating layer which is coated inside the PP surface coating layer and composed of PP and calcium carbonate. The production method includes the steps that the sandwich PP material and the calcium carbonate are evenly mixed; a surface coating layer extruder and a core coating layer extruder are prepared; surface coating layer raw materials are divided into two portions after extruded by the surface coating layer extruder, a portion of core coating layer raw materials is coated by the two portions of surface coating layer raw materials in a die orifice, and the raw materials are co-extruded to from a packaging belt blank; the packaging belt blank is cooled and placed into a heating stretching oven for stretching through a drawing roller; after the stretching, the packaging belt blank is subjected to embossing and placed into a sizing annealing oven for annealing; and after sizing, the packaging belt blank is dragged and rolled for forming after cooling. The packaging belt can bear various weights, resource waste is reduced during the production process, and the production cost is reduced. |
