The following aspects need to be considered when selecting packing boxes:
Specification adaptation: First, measure the maximum outer dimensions of the items to be packed, and reserve 2-5 cm of buffer space in length, width, and height to ensure that the items will not be damaged by squeezing during transportation. For special-shaped items, customized lining or partition devices should be used.
Material performance:
Corrugated cardboard boxes: Economical choice, suitable for dry goods under 15 kg.
Polyethylene turnover boxes: Strong weather resistance, suitable for cold chain logistics recycling.
Plywood boxes: Strong carrying capacity, up to 200 kg, requires shockproof treatment.
Paper materials: Such as corrugated cardboard and kraft paper, suitable for packaging of general items, with good buffering performance and tear resistance.
Plastic materials: Such as bubble pads and plastic films, suitable for fragile items and items that need to be dust-proof and moisture-proof.
Wooden materials: such as plywood boxes, suitable for heavy items or items with high packaging strength requirements.
Load-bearing standard verification:
Static load-bearing: The stacking height of empty boxes does not exceed the marked layer limit.
Dynamic load-bearing: Under road transportation conditions, a 1.5 times safety factor must be met.
Edge pressure strength: Carton products should be ≥7kN/m, which can be verified by BST test.
Enhanced protection function:
Waterproof treatment: Use PE coated carton or sealed plastic box.
Moisture-proof measures: When the desiccant is built-in, the adsorption per unit volume must be calculated.
Seismic design: Fragile items should be used with cushioning materials such as honeycomb cardboard.
