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 ℃.
