针对国内蛋黄派食品的外包装对产品的保护性能水平层次差别较大的现象，利用多种具有物联网信息化功能的包装检测设备及数据分析平台，对不同品牌蛋黄派的镀铝复合膜的物理机械性能、阻隔性能以及溶剂残留等质量管控指标快速地进行了相关试验；将试验数据进行了比较，结合蛋黄派食品的特性以及镀铝复合膜的生产工艺，分析了不同镀铝复合膜包装质量差异的原因，为蛋黄派食品企业在外包装质量控制方面提供参考依据。

In view of the phenomenon that domestic external packaging for custard-pie has different protection performance, tests were carried out rapidly on aluminum composite film for various brands custard-pie packaging by packaging testing machines and data analysis platform to get quality control indexes, such as mechanical properties, barrier property, residual solvent and so on. These equipments were internet of thing and informatization. The experimental data were compared. The reason of quality difference of various aluminum composite films was analyzed combining with the custard-pie characteristics and production technology. The purpose was to provide valuable reference for quality control of external packaging of custard-pie.
