Boxes split open on motorway slip roads. Pallets arrive leaning at worrying angles. Products that left a warehouse pristine turn up scratched, crushed or unusable.
Packaging failure in transit is one of the most persistent and costly problems in modern supply chains, affecting manufacturers, distributors and retailers alike. Despite advances in materials and logistics technology, transport damage remains a leading cause of product loss, customer complaints and avoidable waste.

Understanding why packaging fails in transit is the first step towards reducing damage, protecting goods and improving delivery performance. The causes are rarely mysterious. They usually stem from a mismatch between packaging design, real-world transport conditions and human handling.
Packaging design that does not reflect real transport conditions
One of the most common reasons packaging fails during transport is that it is designed for ideal conditions rather than actual journeys. In theory, a package might only need to withstand a short trip on a smooth road.
In practice, it may experience vibration, drops, stacking pressure, temperature changes and repeated handling across multiple touchpoints.
Packaging that looks robust on paper can fail once exposed to sustained vibration from road or rail transport. Micro-movements gradually weaken carton walls, loosen internal fixings or cause products to rub against protective inserts. Over time, this leads to abrasion, cracking or collapse.

By GlobalDataThis is especially common with long-distance freight and international shipping, where journeys involve several modes of transport.
Stacking pressure is another underestimated factor. Warehouses and vehicles are designed to maximise space, meaning boxes are often stacked higher than anticipated during packaging design.
If the outer packaging lacks sufficient compression strength, lower cartons can buckle under the weight, compromising everything above them. This issue frequently appears in palletised loads where packaging was tested individually rather than as part of a stacked system.
Environmental exposure also plays a role. Humidity weakens corrugated board, while extreme temperatures can make plastics brittle or adhesives fail. Packaging that performs well in controlled warehouse environments may deteriorate rapidly in unheated trailers, shipping containers or outdoor loading bays.
When packaging design fails to account for these transport realities, damage becomes a matter of when, not if.
Poor handling and inconsistent logistics practices
Even the best packaging can fail if handling practices are inconsistent or rushed. Modern supply chains involve multiple handlers, from warehouse operatives and forklift drivers to couriers and retail staff. Each transfer introduces risk.
Manual handling remains a significant issue. Boxes marked as fragile are still dropped, slid or thrown during loading and unloading, often due to time pressure.
Repetitive drops from short heights can cause internal damage that is not immediately visible, leading to returns further down the line. Packaging designed only for single-impact protection may not survive repeated minor shocks.
Mechanical handling presents its own challenges. Forklift tines can puncture cartons, conveyors can snag loose wrapping, and automated sorting systems can exert forces far greater than manual handling. Packaging that is not compatible with automated logistics environments is far more likely to fail in transit.
Inconsistent palletisation also contributes to packaging failure. Poorly wrapped pallets, uneven weight distribution or mixed box sizes reduce load stability. During transit, this instability leads to shifting, crushing or toppling. Stretch wrap applied too loosely allows movement, while over-tight wrapping can deform boxes and damage contents.
Logistics partners may follow different standards and procedures, especially in international shipping. A package that survives one leg of a journey may fail on the next due to unfamiliar handling methods. Without clear packaging specifications and training across the supply chain, damage becomes difficult to control.
Cost-driven compromises in packaging materials and testing
Pressure to reduce packaging costs is a reality for most businesses. While cost efficiency matters, it often leads to compromises that increase the risk of transit damage.
Thinner materials, reduced protective inserts or downgraded outer cartons may look acceptable during initial trials but fail under real distribution conditions.
Material substitution is a frequent culprit. Switching from double-wall to single-wall corrugated board, or replacing moulded inserts with generic void fill, can significantly reduce protective performance.
These changes may pass basic quality checks but fall short when exposed to vibration, stacking and repeated handling.
Insufficient packaging testing is another major factor. Laboratory tests are sometimes limited to static compression or single-drop scenarios, which do not reflect the cumulative stresses of transport. Without proper transit simulation testing, weaknesses remain hidden until failures occur in the field.
Packaging failure also arises when product changes are not matched with packaging updates. A slight increase in product weight, a new component or a change in centre of gravity can alter how forces are distributed during transport. Reusing old packaging designs for updated products often results in unexpected damage.
Sustainability initiatives can also introduce risk if not carefully managed. Reducing packaging material or switching to eco-friendly alternatives without understanding their mechanical limits may increase damage rates.
Sustainable packaging must still meet the demands of transit, or the environmental benefits are lost through increased waste and returns.
Reducing the risk of packaging failure in transit
Preventing packaging failure is less about over-engineering and more about alignment. Packaging must match the product, the journey and the handling environment. This starts with realistic assessment of transport conditions, including distance, modes of transport, stacking practices and climate exposure.
Testing should reflect real-world scenarios, not idealised ones. Vibration testing, multi-drop sequences and pallet load simulations provide far more insight than basic strength tests. Packaging that performs well under these conditions is far more likely to protect goods throughout the supply chain.
Clear handling guidelines and consistent palletisation standards help reduce human-related damage. Training logistics partners and standardising packaging specifications across regions improves predictability and reduces weak links.
Finally, cost decisions should consider total landed cost, not just packaging unit price. The expense of damaged goods, returns, replacements and reputational harm often outweighs the savings from lighter or cheaper packaging.
Packaging fails in transit not because the problem is unsolvable, but because it is often underestimated.
By understanding the true causes of transport damage and addressing them systematically, businesses can protect their products, improve customer satisfaction and build more resilient supply chains that stand the test of time.
