Most baked products are soft or crispy in texture. In the distribution process from the central kitchen to the store, or through e-commerce channels to consumers, one of the biggest risks is deformation, fragmentation or appearance damage caused by stacking pressure.Therefore, the structural design of the baking box must have good compression stacking ability to provide a stable “living space” for the internal products.The compression resistance design first stems from the rigidity of the box body material.Commonly used cardboard, corrugated cardboard or plastics (such as PP, PET) need to reach sufficient thickness and stiffness.In terms of structural design, the design of reinforced ribs, double-layer walls, rounded corners or arched top covers can significantly improve the compressive strength of the box body in the vertical direction and prevent it from being crushed when stacking.

The finer design is reflected in the internal support structure.For fragile biscuits, egg rolls, or exquisite pastries, it is not enough to rely on a sturdy outer box. The interior needs to be set up with divider slots, inner brackets, or fixed molds.For example, an inner tray made of pulp molding or foam plastic is used to fix each pastry in separate compartments, which can not only prevent the products from colliding with each other, but also disperse the pressure transmitted from the upper layer through the inner tray structure around the box body, rather than directly acting on the pastry body.For cake products, sometimes a central load-bearing column or edge support table is designed in the box to keep the lid at a safe distance from the surface of the cake.

The development of scientific stacking and transportation specifications is the other half of the solution.The packaging supplier should provide a tested and verified recommendation for the maximum number of safe stacking layers.Logistics operators need to strictly abide by it to avoid super-high-level stacking.Inside the transportation packaging (such as the outer box), you can consider using partitions or putting each baking box in a separate compartment.For e-commerce transportation, the size of the outer box should match the inner box and be filled with sufficient cushioning materials (such as bubble film and inflatable bags) to absorb the impact during transportation.Solving the problem of deformation in the distribution of baking products is a system engineering that requires packaging engineers, production personnel and logistics teams to work together, from packaging structure design, internal fixation methods to external logistics operation specifications, interlocking, in order to ensure that exquisite baking works can still be presented in a perfect form in front of consumers after experiencing the bumps of the journey.
