Warehouse Packing Gear
An optimized pallet layout means nothing if your cartons collapse during transit. To ensure your pallet holds its shape during shipping, you must secure it properly. We strongly recommend using heavy-duty 80-gauge stretch wrap, which provides the puncture resistance and tension required to lock heavy cartons together. Furthermore, to prevent the stretch wrap from crushing the corners of your top layer cartons, always apply cardboard edge protectors along the vertical corners of your pallet before wrapping.
How to Optimize Pallet Packing
Shipping "air" is the most expensive mistake in logistics. When loading cartons onto a standard 48"x40" pallet, poor arrangement can leave wide gaps, reducing the number of units you can ship per pallet and drastically inflating your freight costs. The goal is to maximize "volume utilization" while staying within maximum stack height and weight limits. The math to find the perfect interlocking pattern is complex, requiring you to test rotating the cartons along the X and Y axes. PalletPack's 3D optimization engine handles this instantly. It tests every possible orientation of your carton dimensions against standard US and EU pallet sizes, calculating the most efficient interlocking layer pattern, the maximum number of layers, and the total gross weight.
Frequently Asked Questions
What are standard pallet dimensions?
The most common US pallet (GMA standard) is 48" × 40" and supports up to 2,500 lbs dynamic load. The Euro pallet (EPAL/EUR) is 800mm × 1200mm (31.5" × 47.2"). Other sizes include 42×42" (paint/chemical), 48×48" (drums), and 48×45" (automotive). Always confirm the pallet spec with your warehouse or carrier.
How tall can you stack a pallet for shipping?
Standard maximum pallet height is 48" of product on top of a 6" pallet = 54" total. Some carriers accept up to 72" total for LTL freight. Stack height also depends on container dimensions: a 53-foot trailer interior is 108" high, allowing double-stacking of 54" pallets. Always confirm with your carrier and consider product crush resistance.
Should I rotate cartons on a pallet for better packing?
Yes — rotating cartons (alternating 0° and 90° orientations between layers) creates interlocking layers that prevent shifting during transport. Rotated layouts sometimes fit 5-10% more cartons per layer than uniform orientation. However, some products have 'this side up' restrictions that prevent rotation.
