With 1.5% of pomegranate peel extract (PPE) as antimicrobial agent, polyethylene resin (PE) and polypropylene resin (PP) as base material, PE, PPE—PE, PP/PPE—PE active films were prepared and their basic properties were investigated. Pork stored at refrigeration (4±1) ℃ with PE, PPE—PE, PP/PPE—PE active packaging films, and the effects of preservation were evaluated by total viable count (TVC), total volatile basic nitrogen (TVB-N), pH value, thiobarbituric acid (TBA) value, drip loss and sensory scores. PPE—PE film was 1.96 times the oxygen transmission rate of PE film, 4 times of PP/PPE—PE film. PPE caused the light transmittance of PE film decreased, haze and tensile strength increased. On 6^th day, the total viable counts (TVC) of pork samples in PE group increased to 6.54 lg (CFU/g) from 3.54 lg (CFU/g), while TVC of pork samples in PP/PPE—PE and PPE—PE Group exceeded 6 lg (CFU/g) on day 8. PP/PPE—PE and PPE—PE active packaging films can extend the shelf life of by approximately 2～3 days, compared with control treatment. And the preservation effect of PP/PPE—PE active packaging film was relatively better than that of the PPE—PE active packaging film.
