| 摘要:在3层共挤流延聚丙烯薄膜（CPP薄膜）的原料树脂中，加入POE树脂，进行了CPP薄膜的改性，研究了在CPP薄膜的电晕层、芯层、热封层分别加入POE树脂后，薄膜的相应性能。结果表明：在电晕层中加入质量分数为15%的POE树脂，可以将CPP薄膜真空镀铝后的铝层附着牢度提高1倍；在芯层中加入质量分数为25%的POE树脂，可以使CPP薄膜的模量降低36.3%；在热封层中加入质量分数为40%的POE树脂，可以将CPP薄膜的热封温度降低10 ℃。 |

| Abstract:POE resin was added into three layer coextrusion CPP film to modify its performace. The performance of the CPP film after addition of POE resin into the corona layer, core layer, and heat sealing layer were studied. The results showed that 15% POE resin addition into the corona layer can double the aluminum adhesive strength of CPP film after vacuum metallization; 25% POE resin addition into the core layer can reduce CPP film modulus by 36.3%; 40% POE resin addition into the heat sealing layer can reduce CPP film's heat sealing temperature by 10 ℃. |
| Key words: POE CPP film adhesive strength modulus heat sealing temperature |
