UnverifiedPP支撑板提供基本定型能力，但整体硬度不如塑料收纳箱，叠放层数不宜超过两三层否则易变形塌陷83% similarUnverifiedPP硬框架使箱体承重较强、可多层叠放，但相比可压缩软箱，空箱占用空间较大，不适合收纳箱本身需要折叠存放的场景。79% similarUnverified极致轻量的代价是箱壁较薄，虽然Curv韧性强不易碎裂，但抗压刚性不如传统PC硬壳，箱内易碎物品需要额外保护77% similarUnverified多箱叠放时需确认箱盖承重能力，叠放层数过多存在变形或卡扣受压损坏风险，建议不超过三层叠放。77% similarUnverified全折叠设计不用时可压平存放，但软箱在重物长期挤压下容易变形、撑不回原形，与PP硬箱相比耐久性有差距76% similar
