UnverifiedPP材质厚度影响耐用性，壁厚＜1mm的薄盒受力易变形开裂，承重物品（工具、餐具）建议选壁厚1.5mm以上或加厚款85% similarUnverifiedPP材质分隔格常规壁厚1.5-2mm可承受日常小物，若放置玻璃瓶、罐头等重物需选壁厚≥2.5mm或加强筋结构，否则底部易变形凹陷82% similarUnverified壁厚是耐用度核心，PP箱壁厚≥1.5mm才不易在负重叠放下变形塌陷，超薄款(＜1mm)半年即软化，套装低价常靠减薄壁厚实现81% similarUnverified材质厚度看壁厚而非整体重量，加厚PP箱壁厚应≥1.5mm、承重结构处有加强筋，装满衣物堆叠不塌陷；廉价薄壁箱装满后侧壁外凸导致床底卡住抽不出76% similarUnverified买壁厚而非只看外观尺寸：同容积下PP箱壁厚2mm以上才有足够承重与堆叠稳定性，薄壁款（<1.5mm）装重物会明显外鼓变形76% similar
