目的 研究内装物温度对瓦楞纸箱抗压强度的影响。方法 采用理论与实验相结合的方式， 分析60 ℃的热装物对瓦楞纸箱抗压强度的影响， 并提出了改善措施。实验主要包括： 常温环境和恒温恒湿室内的对比实验； 0201型六层复合的普通纸箱与内层涂布防水层纸箱的对比实验。结果 66.7%的普通纸箱实验中， 装热态物的纸箱抗压强度平均下降5.5%左右； 防水涂布实验箱的抗压强度平均高于常规纸箱20%左右。结论 防水涂料涂布的纸箱可以有效地抵消热装物对纸箱强度的影响。

The aim of this work was to study the influence of hot charging contents on the compression strength of corrugated box. The influence of 60 ℃ contents on the compression strength of cartons was analyzed by means of combining theory and experiments, and improvement measures were put forward. Experiments mainly included: contrast experiment in normal temperature environment and constant temperature and humidity room, and contrast experiment of the type 0201 six composite layer of ordinary and waterproof cartons. In 66.7% of the ordinary carton experiment, the compressive strength of experimental boxes fell by 5.5% on average as compared with the control cartons. The compressive strength of Waterproof experimental cartons was superior to that of common cartons by 20% on average. In conclusion, cartons coated with waterproof paint could effectively counteract the effects of hot charging content on the compression strength of cartons.
