中文摘要:

      研究了蓄冷剂和选择透过性薄膜对普通瓦楞纸箱的温度阻隔性能的影响，探讨了复合瓦楞纸箱的温度（热量）传递效果。3种包装方式下的放热、吸热结果表明，蓄冷剂和选择透过性薄膜的双重调节作用对普通瓦楞纸箱的温度阻隔效果最优，而无蓄冷剂、只有选择透过性薄膜的单独调节作用也能提高普通瓦楞纸箱的温度阻隔性能，进而合理选用蓄冷剂、选择透过性薄膜可有效提高普通瓦楞纸箱的隔热性能，改善气调纸箱包装技术的保鲜作用。

Abstract:

      The influence of coolant and perm-selectivity film on heat insulating property of corrugated box was researched, and the temperature (or heat) transfer effect of composite corrugated box was discussed. The results of three package modes for corrugated box during exothermic and decalescence experiments showed that, the double-modulation with coolant and perm-selectivity film on usual corrugated box has the best heat insulating property, the single-modulation with only perm-selectivity film and no coolant on corrugated box can also increase the heat insulating property of usual corrugated box. Therefore the heat insulating property of usual corrugated box may be effectively enhanced by the combined usage of coolant and perm-selectivity film, then the keeping-fresh function of modified atmosphere packaging technology with corrugated box can be further improved.
