目的 研究葫芦膜泡径、厚度、充气量、材料降解性对缓冲包装单元承载压力的影响。方法 针对不同规格的葫芦膜进行静态压缩实验，测定其单元承载压力-变形特性，分析静态压缩速度、充气速度、泡径、厚度、材料降解性对其单元承载压力的影响。结果 在一定范围内，静态压缩速度和充气速度对其单元承载压力的影响不显著;超出这一范围后，静态压缩速度越大，充气速度越慢，则相同压缩形变条件下葫芦膜的单元承载压力越大;葫芦膜的泡径越小，薄膜厚度越大，在相同压缩形变条件下单元承载压力越大;在尺寸规格相同的情况下，降解材质的葫芦膜的单元承压性能远低于非降解材质的葫芦膜。结论 研究结果对葫芦膜包装材料的选择和使用有一定的指导意义。

The work aims to obtain the effects of bubble diameter, film thickness, inflation amount of gourd films and material degradability on the bearing pressure of cushion packaging units of gourd films. Static compression experiments were carried out for different specifications of gourd films, and the unit bearing pressure-deformation characteristics were measured. The effects of static compression speed, inflation speed of gourd film, bubble diameter, film thickness and material degradability on the unit bearing pressure were analyzed. In a certain range, the static compression speed and the inflation speed of gourd film had no significant effects on the unit bearing pressure. Beyond a certain range, the higher the static compression speed, the slower the inflation speed of the gourd film, and the greater the unit bearing pressure of the gourd film under the same compression deformation condition. The smaller the bubble diameter of the gourd film, the greater the film thickness, and the greater the unit bearing pressure under the same compression deformation condition. Under the same size and specification, the unit pressure-bearing performance of the degradable material gourd film was much lower than that of the non-degradable material gourd film. The research results have certain guiding significance for the selection and use of gourd film packaging materials.
