Physical damage is one of the primary quality problems affecting goods during transportation. The main causes include poor handling practices, overloading, improper stacking arrangements, and selecting inadequate packaging materials. Preventing heat accumulation requires enhanced ventilation — when stacking packages, ensure air can flow freely between them. It is especially important to utilize the airflow generated by moving vehicles to make air pass through the cargo stack and even through individual packages. During hot seasons, cover goods appropriately, conduct quality inspections, select packaging suited to the fruit’s characteristics, leave ventilation gaps when loading, and maintain the required temperature throughout transit.
Poor Handling — A Persistent Problem
Poor handling has long been a major cause of fruit quality damage. While packaging significantly reduces physical damage to refrigerated goods during transport, it cannot fully prevent the effects of mishandling. The vast majority of fruits contain over 80% water, making them tender, perishable products. Without careful handling during loading and unloading, damage is inevitable. Damaged fruit is difficult to store — this requires well-built cold storage facilities, particularly high-quality insulation panels and cold room doors. Without proper insulation, damaged fruit rapidly deteriorates. Loading and unloading must be performed with extreme care.
Overloading — A Widespread Issue
Overloading is a common problem in many countries. Transport operators often try to load as much as possible onto a single vehicle to maximize economic returns from each shipment. This problem becomes even more concerning when the transport worker’s compensation has no link to product quality. Additionally, workers who stand or sit on packaged goods during loading or transit cause damage similar to overloading — a scenario not uncommon in many places and one that must be actively prevented.
Moisture Retention — The Key to Fruit Freshness
Fruit preservation largely comes down to moisture retention. Water loss during post-harvest transportation is unavoidable, which is why enhanced refrigeration is crucial. Fruits also lose water through respiratory metabolism. The primary method for controlling water loss during transport is reducing airflow around the product — airflow across fruit surfaces is a key factor affecting dehydration rate. The faster air moves across fruit surfaces, the faster the dehydration.
Yet this requirement directly conflicts with the need for air circulation to prevent heat buildup. A balanced compromise is necessary, and the specific balance depends on each fruit variety’s susceptibility to wilting.
Stacking Arrangements — Critical for Damage Prevention
Stacking arrangement during transport is critically important. Even without overloading, fruit must be carefully and orderly stacked to maximize protection. Packages should be packed tightly together so that there is minimal movement between them during transit. Packages should fill the entire vehicle floor to ensure even distribution of static pressure, and stacking must not exceed the vehicle’s edges.
A fundamental stacking principle: the lower containers should bear the weight of the entire stack above them — not the fruit inside the lower containers. This is why rectangular containers perform far better than irregular shapes. Corrugated fiberboard boxes and paper bags, compared to bulk-packed goods without packaging, also significantly reduce fruit water loss and help maintain freshness. For long-distance transportation, suitable packaging is essential to prevent dehydration.
Rectangular containers (such as corrugated boxes) are strongly preferred. Irregularly shaped containers like bamboo baskets or wicker baskets are far more difficult to stack into an ideal arrangement. The proper container choice — combined with correct stacking technique — forms the foundation of effective fruit transport packaging.
