Why Proper Freight Packaging Matters
Freight packaging is one of the most overlooked aspects of shipping, yet it has a direct impact on your bottom line. Poorly packaged freight leads to damage claims, re-shipping costs, unhappy customers, and higher insurance premiums. Carriers handle thousands of shipments daily, and your freight will be loaded, unloaded, stacked, and transferred multiple times before reaching its destination.
Good packaging protects your cargo, reduces your freight class (lowering costs), and prevents the frustration and expense of damage claims. This guide covers everything you need to know to package freight like a professional.
Choosing the Right Packaging Method
The packaging method you choose depends on your cargo type, weight, fragility, and shipping method. Here are the main options:
Palletizing
Palletizing is the most common freight packaging method. Goods are stacked on a standard pallet (typically 48" x 40" in North America) and secured with stretch wrap, strapping, or both. Palletized freight is easy for carriers to handle with forklifts, reduces loading time, and protects goods from ground-level moisture and contact.
Best for: Boxes, cartons, bags, and any goods that can be stacked. Works for both LTL and FTL shipments.
Crating
Custom wooden crates provide maximum protection for heavy, fragile, or irregularly shaped items. Crates are built to the exact dimensions of your cargo and can include internal bracing, foam padding, and moisture barriers. While more expensive than palletizing, crating is essential for high-value or delicate equipment.
Best for: Machinery, electronics, artwork, glass, and other fragile or high-value items.
Corrugated Boxes
For smaller freight shipments, heavy-duty corrugated boxes rated for the appropriate weight are effective. Use double-wall or triple-wall corrugated for heavier items. Always use boxes rated for the weight they will carry, as standard shipping boxes are not designed for freight handling.
Best for: Lighter items, consumer goods, parts, and components under 70 pounds per box.
Banding and Strapping
Steel or polyester strapping secures items to pallets or bundles loose items together. Banding is essential for lumber, pipes, metal stock, and other materials that cannot be boxed. Use corner protectors under strapping to prevent damage to edges.
Step-by-Step Palletizing Guide
Step 1: Select the Right Pallet
Use standard GMA pallets (48" x 40") for compatibility with carrier equipment. Inspect pallets for broken boards, protruding nails, and structural integrity. Avoid pallets with missing or cracked deck boards, as they can collapse during transport. For export shipments, use ISPM-15 certified heat-treated pallets to comply with international phytosanitary regulations.
Step 2: Stack Properly
Place the heaviest and largest items on the bottom. Stack boxes in a brick-lay pattern (alternating direction each layer) for maximum stability. Do not let items overhang the pallet edges, as overhanging cargo is prone to damage and creates handling problems. Keep the stack height reasonable, typically no more than 60 inches from the pallet deck for LTL shipments.
Step 3: Secure with Stretch Wrap
Apply at least three to five layers of 80-gauge (or thicker) stretch wrap around the entire pallet load. Start at the base and work upward, overlapping each layer by at least 50%. Wrap the film around the pallet deck boards at the bottom to anchor the load to the pallet. A properly wrapped pallet should feel tight and immovable when pushed.
Step 4: Add Strapping
For heavy loads, add two vertical and two horizontal polyester or steel straps over the stretch wrap. Strapping provides additional security during transit and prevents the load from shifting if the stretch wrap loosens.
Step 5: Label Clearly
Apply shipping labels on at least two sides of the pallet. Include the destination address, shipper address, PO number, and any handling instructions. Use large, clear labels that can be read from a distance. Mark fragile items with "FRAGILE" and "THIS SIDE UP" labels as needed.
Protecting Fragile Items
Fragile items require extra attention during packaging:
- Internal Cushioning: Use foam inserts, bubble wrap, or air pillows to fill void space inside boxes. Items should not be able to move or shift within their packaging.
- Double Boxing: Place the item in an inner box with cushioning, then place that box inside a larger outer box with additional cushioning between them. This creates two layers of protection.
- Corner Protection: Apply foam or cardboard corner protectors to shield edges and corners, which are the most vulnerable points during handling.
- Vibration Dampening: For electronics and precision equipment, use anti-vibration foam or suspension packaging that isolates the item from transport vibrations.
- Moisture Protection: Use desiccant packets and moisture barrier bags for items sensitive to humidity, especially for ocean freight where containers can experience condensation.
Common Packaging Mistakes That Cause Damage
Reusing Worn Boxes
Used boxes lose up to 50% of their stacking strength. A box that survived one shipment may collapse under the same weight during a second trip. Always use new boxes for freight shipments, or at minimum inspect used boxes carefully for any structural weakness.
Insufficient Void Fill
Empty space inside a box is your cargo's worst enemy. Items that can shift during transport will collide with each other and the box walls. Fill every gap with appropriate cushioning material.
Overloading Pallets
Standard pallets support approximately 2,500 pounds of evenly distributed weight. Exceeding this limit or concentrating weight in one area can cause pallet failure, which damages your cargo and creates safety hazards in the carrier's terminal.
Poor Stretch Wrapping
Too few layers of stretch wrap, not anchoring to the pallet base, or using low-quality film results in loads that shift and topple during transit. Invest in quality wrap and apply it generously.
How Packaging Affects Your Freight Costs
Packaging directly impacts your shipping costs in several ways:
- Dimensional Weight: Oversized packaging increases dimensional weight, which raises your freight charges. Use the smallest packaging that adequately protects your goods.
- Freight Class: Denser, more compact packaging can qualify for a lower freight class, reducing your per-pound rate.
- Damage Claims: Proper packaging reduces damage claims, which keeps your insurance costs low and maintains good relationships with carriers.
- Handling Surcharges: Non-standard packaging (oversized, non-stackable, or irregularly shaped) may trigger additional handling surcharges from carriers.
