目的 开发可折叠水产品运输保温包装箱。方法 借鉴纸包装结构设计中的可折叠设计思想， 以塑料中空板为箱体材料， 结合保温材料， 得到可折叠水产品运输保温包装箱结构设计方案， 将其与普通塑料泡沫箱进行物流成本对比分析， 通过抗压试验测定分析不同类型水产品运输保温包装箱的抗压强度。结果 该包装箱实现了空箱储运时可折叠， 降低了物流成本； 箱子抗压强度好， 优于市场上常用的水产品塑料泡沫箱， 同时可通过调整外箱体材料及保温材料来优化包装箱的各方面性能； 在采用该包装箱进行水产品包装时， 需在内包装中增加塑料袋来满足水产品物流运输过程中防水渗漏的要求。结论 该可折叠水产品运输保温包装箱的结构设计方案可行， 力学性能好。

The study aimed to develop a foldable insulation packaging container for aquatic products. A structure design solution of foldable insulation packaging container for aquatic product was obtained based on foldable design idea of paper packaging structure design, using plastic corrugated board and insulation material. Its logistic cost was analyzed compared with the foam box. The mechanical property was measured and analyzed through compression experiment. The results showed that application of this packaging container could significantly reduce the logistics cost when the empty container was in storage and transportation. Its compression strength was better than the common plastic foam box of aquatic product. The global performance could be optimized by adjusting materials of outer box and insulation materials. It was required to add a big plastic bag outside of the aquatic product to satisfy the requirement of avoiding water leakage during logistics when using this packaging container to pack the aquatic product. Taken together, the structure design solution of this foldable insulation packaging container for aquatic product was feasible and sturdy, which provided a basis for the subsequent study on structure optimization, thermal insulation experiment and it application for aquatic products packaging.
