Integrated Packaging for Heavy and Bulky Products
Heavy Duty Cardboard Pallet Boxes are designed for large, heavy, or palletized products. They are commonly made from AA-flute or AAA-flute corrugated board. The box can be combined with a paper pallet, wooden pallet, or another load-bearing base to form one complete packaging unit.
This structure is suitable for forklift trucks, pallet trucks, and warehouse handling equipment. Compared with standard shipping cartons, it places greater emphasis on bottom load capacity, box rigidity, weight distribution, and loading efficiency.
Typical applications include automotive parts, metal components, mechanical equipment, motors, pump bodies, valves, and bulk industrial parts. The box and pallet dimensions can also be planned according to warehouse locations and container space, helping products remain more orderly during storage and loading.

Structure Designed Around Weight and Handling
The external dimensions can be customized according to the product outline, total packed weight, bottom load points, and planned loading method. For irregular parts, products with an offset center of gravity, or components that may collide with each other, additional protective structures can be added.
Available options include surrounding panels, corner protectors, dividers, positioning slots, cushioning inserts, and local reinforcement. Forklift entry direction, pallet capacity, and bottom structure must be considered together. Maximum load capacity should not be determined only by the box dimensions or flute type.
For projects requiring multi-layer stacking, the board configuration and stacking height should be selected according to dynamic loads, storage time, and transportation routes. Heavy Duty Cardboard Pallet Boxes can therefore be developed around the complete handling process rather than treated as ordinary oversized cartons.

Custom Development and Factory Processing
Hangzhou Boyi New Materials Co., Ltd. can design the packaging structure according to product weight, center of gravity, and handling procedures. The company provides material selection, sample production, die-cutting, stitching, gluing, and batch manufacturing support.
The factory has an operating area of approximately 5,000 square meters. It is equipped with a corrugated board production line, automatic box stitching machine, automatic high-speed folder gluer, and automatic die-cutting machine. The forming method can be selected according to the final heavy-duty box structure.
Customers may provide technical drawings or physical product samples. The team can then adjust the panel height, opening direction, pallet combination, and internal fixing structure according to the actual loading method.

Sampling, Inspection, and Order Validation
A sample can be produced before formal production. Custom sample development can take approximately 5–10 days at the fastest, depending on the structure and processing difficulty. The normal production period for customized products is 10–15 days.
Quality control includes incoming material inspection records, production sampling, warehouse entry and outgoing inspection, and retention of bulk-production samples. A full inspection can be arranged before packing. Third-party inspection is also accepted.
Before confirming a bulk order, the sample should be loaded with the actual product. Load-bearing, stacking, handling, or simulated transport tests can then be carried out according to project requirements. This process helps confirm that the pallet, box bottom, forklift entry, and reinforced areas work together correctly.
