【摘要】：正近日,上海石化收到授权专利证书,"一种用于制造高温蒸煮CPP薄膜的聚丙烯树脂组合物及其高温蒸煮CPP薄膜"和"一种高温蒸煮CPP薄膜的聚丙烯树脂组合物的制造方法"被国家知识产权局批准为技术发明专利。高温蒸煮级CPP膜,即流延聚丙烯薄膜,具有拉伸强度高、耐冲击强度高、耐介质性好等特点,用它制成的蒸煮袋可在135℃高温下杀菌10~20 min,可广泛应用于食品软罐头等新型包装材料。此前,国内尚未开发出适用于高温蒸煮的CPP专用料,生产原料基本依赖进口。经国内主要加工企业应用,上海石化高温蒸煮膜专用料新产品加工性能好,各项
[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，
