Yes, stackable boxes can cause crushed items in lower levels if the boxes are not strong enough to support the weight above, or if the items inside are fragile and lack proper support.
The weight of boxes stacked on top of each other exerts pressure on the boxes below. If the boxes themselves are made of weak material, like thin cardboard, they can buckle or collapse under the load. Similarly, if the items inside the lower boxes are delicate or irregularly shaped, they may not be able to withstand the pressure from above, leading to crushing. The distribution of weight within each box also plays a role. If heavier items are concentrated in one area, it can create uneven pressure points that increase the risk of damage. Furthermore, the stacking method matters. Stacking boxes directly on top of each other without any support or reinforcement can amplify the pressure on the lower levels.
When stacking boxes, always place the heaviest boxes at the bottom and the lightest boxes on top. This minimizes the pressure on the lower levels and reduces the risk of crushing. Also, use boxes of similar size and shape for more stable stacking.
