Avoid These Common Reefer Packing Errors That Could Damage Your Valued Produce.

Poor Packing Techniques can Compromise Cargo Quality

Reefer containers are vital for transporting temperature-sensitive products like fresh produce, meat, dairy and pharmaceuticals. But even with the right equipment, poor packing techniques can compromise cargo quality and lead to profit losses.

To ensure your goods arrive in optimal condition, it’s essential to follow correct loading practices.

Here's a practical guide to help you get the most from your refrigerated container:

1. Pre-Cool Both Cargo and Container.

Why It Matters:

Reefer containers are designed to maintain a set temperature - not to cool warm cargo. If products are loaded while still warm, it can take longer to stabilise the internal environment, increasing the risk of spoilage.

Best Practices:

Pre-cool goods to the required temperature before loading.
Make sure the container is set to the correct temperature beforehand.
Avoid leaving container doors open unnecessarily during loading.
Don’t overload the reefer with warm produce directly from the field or facility.

2. Manage Airflow Effectively.

Why It Matters:

Consistent airflow is critical for even temperature distribution inside the reefer. Blockages or poor stacking can result in uneven cooling and hot spots.

Best Practices:

Place cargo on pallets or dunnage to allow airflow beneath.
Keep vents clear and avoid packing items tightly against the container walls.
Leave small spaces between cargo stacks to support air circulation.
Do not block the T-bar floor - it’s essential for airflow under and around the load.
Pack cargo up to the end of the container (near the rear doors) to support airflow return.

3. Tailor Your Packing to the Type of Cargo.

Frozen Goods:

Stack cargo tightly to allow air to move through the load.
Minimise gaps to maintain a uniform temperature.
Use dividers to prevent load shifting during transport.

Chilled Goods:

Air should circulate around the cargo, not through it.
Avoid overloading the container, which restricts airflow.
Never block the floor channels or side walls, as they help with temperature consistency.
