【摘要】：正近日,上海石化收到授權(quán)專利證書,"一種用于制造高溫蒸煮CPP薄膜的聚丙烯樹脂組合物及其高溫蒸煮CPP薄膜"和"一種高溫蒸煮CPP薄膜的聚丙烯樹脂組合物的制造方法"被國家知識產(chǎn)權(quán)局批準為技術(shù)發(fā)明專利。高溫蒸煮級CPP膜,即流延聚丙烯薄膜,具有拉伸強度高、耐沖擊強度高、耐介質(zhì)性好等特點,用它制成的蒸煮袋可在135℃高溫下殺菌10~20 min,可廣泛應(yīng)用于食品軟罐頭等新型包裝材料。此前,國內(nèi)尚未開發(fā)出適用于高溫蒸煮的CPP專用料,生產(chǎn)原料基本依賴進口。經(jīng)國內(nèi)主要加工企業(yè)應(yīng)用,上海石化高溫蒸煮膜專用料新產(chǎn)品加工性能好,各項
[Abstract]:Recently, Shanghai Petrochemical received an authorized patent certificate. A polypropylene resin composition for manufacturing high temperature cooking CPP film and its high temperature cooking CPP film and a method for manufacturing a polypropylene resin composition for high temperature cooking CPP film are approved as technical invention patents by the State intellectual property Office. High temperature cooking grade CPP film, that is, casting polypropylene film, has the characteristics of high tensile strength, high impact strength and good medium resistance. The cooking bag made with it can sterilize 1020 min, at 135 鈩，
