Costly Reefer Packing Mistakes That Could Jeopardize Your Cargo and Profits

Reefer containers play a critical role in storing temperature sensitive goods, ensuring they remain fresh and undamaged.  However, incorrect packing can lead to temperature fluctuations, uneven cooling and product spoilage.

To get the most out of your reefer container, proper loading techniques must be followed.

Pre-Cooling the Cargo and Container

 Why It Matters:

Reefer containers are designed to maintain temperature, not to cool down products from ambient temperatures.  If warm goods are loaded, it can take longer to reach the desired temperature, affecting product quality.

Best Practices:

  • Pre-cool the cargo to the correct temperature before loading.
  • Ensure the reefer container is at the correct setpoint before starting the loading process.
  • Do not overload the cooling system by introducing warm cargo.

Proper Airflow Management

Why It Matters:

Reefers rely on continuous airflow to maintain a consistent temperature.   Blocking air circulation can create hot spots and uneven cooling.

Best Practices:

  • Use pallets or dunnage to keep cargo off the floor and allow air circulation beneath.
  • Avoid blocking air vents at the front or rear of the container.
  • Leave space between cargo stacks to allow proper air distribution.
  • Never push cargo against the walls - side airflow is essential for even cooling.
  • Pack your cargo as close to the back panel as possible for even air flow.

Loading Patterns for Different Types of Cargo

Frozen Goods

  • Airflow should be forced through the cargo to maintain uniform freezing.
  • Stack cargo tightly with minimal gaps to ensure even cooling.
  • Use plastic or cardboard dividers to prevent shifting during transport.

Chilled Goods

  • Airflow should circulate around the cargo, not force through it.
  • Do not block the T-bar floor, as this allows cold air to flow evenly.
  • Avoid overloading the container, as this restricts airflow and cooling efficiency.


Key Takeaways for Optimal Reefer Packing

  • Pre-cool both cargo and the container before loading.
  • Ensure proper airflow by keeping vents, floors, and walls clear.
  • Use the right stacking technique based on whether goods are frozen or chilled.
  • Monitor temperature regularly to avoid spoilage or losses.
