| titleOfInvention | Three-layer coextrusion plastic fertilizer packaging bag |
| abstract | The invention discloses a three-layer coextrusion plastic fertilizer packaging bag. The bag comprises an inner layer plastic film, a middle layer plastic film and an outer layer plastic film and is prepared through a three-layer coextrusion film blowing technology, wherein the raw material of the inner layer plastic film is selected from polyethylene (PE); and raw materials of the outer layer and middle layer plastic films are selected from mixtures of polypropylene (PP), the PE and a propylene-based elastomer. The PP and the propylene-based elastomer exist in the outer layer and middle layer materials, and the inner layer material is the PE, so the compatibility between the PP and the PE is improved, thereby the packaging bag prepared in the invention has a higher heat-sealing peeling strength than bags prepared from other PP-PE coextrusion films, has an enhanced packaging fastness, an enhanced seal moisture resistance and an enhanced heat-sealing pollution resistance, and allows shelf lives of products stored in the bag of the invention to be longer than that of products stored in plastic woven packaging bags; the bag of the invention has the advantages of good heat resistance, good tensile strength and good creep resistance, can adapt to high loading temperatures and does not deform when stacking is carried out after hot loading; and the bag of the invention is lighter than three-layer coextrusion PE film bags with a same thickness, so the bag of the invention can be widely applied to the packaging industry, and is especially suitable for fertilizer packaging. |
