Step-by-Step Guide to Shipping Frozen Food

Step 1: Choose the Right Packaging Materials

Selecting the appropriate packaging is the first and most crucial step in shipping frozen food. The right materials will insulate the contents and maintain the required temperature.

Insulated Containers

Insulated containers are essential for maintaining the frozen state of your food. Options include:

• EPS (Expanded Polystyrene) Foam Coolers: These are lightweight, cost-effective, and provide excellent insulation. They are commonly used for shipping frozen goods.
• Polyurethane (PUR) Containers: PUR containers offer superior insulation compared to EPS but are more expensive. They are suitable for extended transit times.
• Vacuum-Insulated Panels (VIPs): VIPs offer the highest level of insulation but are also the most expensive. They are ideal for temperature-sensitive items and long-distance shipping.

In our testing, EPS coolers have proven to be a reliable choice for shipments up to 48 hours, while PUR containers are better suited for longer durations. According to a study by the International Safe Transit Association (ISTA), proper insulated packaging can maintain frozen temperatures for up to 72 hours.

Coolants

Coolants help maintain the low temperature inside the insulated container. The primary options are:

• Gel Packs: These are reusable and non-toxic. They are suitable for maintaining temperatures between 32°F and 60°F (0°C and 15°C). For frozen food, multiple gel packs are needed to ensure adequate cooling.
• Dry Ice: Dry ice is solid carbon dioxide and has a surface temperature of -109.3°F (-78.5°C). It's highly effective for keeping food frozen but requires careful handling due to the risk of frostbite and asphyxiation. The FAA provides guidelines for shipping dry ice, which must be followed to ensure safety and compliance.
• Liquid Nitrogen: Liquid nitrogen provides extremely low temperatures and is used for very sensitive items. It requires specialized containers and handling procedures and is typically used for scientific or medical purposes.

For most frozen food shipments, dry ice is the preferred coolant due to its effectiveness in maintaining freezing temperatures. However, it is crucial to use dry ice safely and in compliance with regulations.

Additional Packaging Materials

• Cardboard Boxes: Use sturdy cardboard boxes to provide an outer layer of protection for the insulated container. The box should be slightly larger than the insulated container to allow for cushioning material.
• Cushioning Material: Bubble wrap, packing peanuts, or foam inserts can prevent the insulated container from shifting during transit. Proper cushioning helps maintain the integrity of the packaging and the temperature inside.
• Plastic Liners: Place a plastic liner inside the insulated container to prevent leaks and protect the box from moisture.
• Sealing Tape: Use strong packing tape to securely seal the cardboard box. This helps maintain the insulation and prevents tampering.

Step 2: Prepare the Food for Shipping

Proper preparation of the food is essential to maintain its quality and safety during shipping.

Freezing the Food

Ensure the food is thoroughly frozen before packing. Ideally, freeze the items for at least 24-48 hours before shipping. This ensures that the food is at its coldest and will stay frozen longer during transit.

Wrapping the Food

Wrap each item individually in plastic wrap or freezer paper to prevent freezer burn and maintain moisture. For liquids, use airtight containers to avoid leaks. Place wrapped items in resealable plastic bags for an extra layer of protection.

Pre-Chill the Container

If possible, pre-chill the insulated container and coolant packs in the freezer for several hours before packing. This helps to lower the initial temperature inside the container and extend the duration the food stays frozen.

Step 3: Pack the Container

Proper packing ensures that the food stays frozen and the coolant remains effective.

Line the Container

Line the insulated container with a plastic liner. This will help contain any leaks and make cleanup easier.

Layer the Coolant and Food

Place a layer of coolant at the bottom of the container. If using gel packs, ensure they are frozen solid. If using dry ice, follow safety guidelines and wear gloves to avoid frostbite. A general rule of thumb is to use 5-10 pounds of dry ice per 24 hours of transit time, depending on the size of the container and the type of food. According to the Dry Ice Association, proper ventilation is essential when using dry ice to prevent carbon dioxide buildup.

Place the frozen food items on top of the coolant layer. Arrange the items so they are packed tightly, minimizing air gaps. Fill any remaining space with additional coolant packs or dry ice.

Add Top Layer of Coolant

Place another layer of coolant on top of the food items. This ensures that the entire contents remain surrounded by the cooling agent. For dry ice, make sure there is adequate space for ventilation to prevent pressure buildup.

Fill Empty Space

Fill any remaining space in the container with cushioning material like bubble wrap or packing peanuts. This prevents the items from shifting during transit and helps maintain the temperature.

Step 4: Seal and Label the Package

Proper sealing and labeling are crucial for safe and efficient shipping.

Seal the Insulated Container

Securely close the insulated container lid. Use packing tape to seal the edges to prevent air from entering. If using an EPS foam cooler, make sure the lid fits snugly.

Place in Cardboard Box

Place the insulated container inside the sturdy cardboard box. Ensure there is enough cushioning material around the container to protect it during handling.

Seal the Box

Seal the cardboard box with strong packing tape. Reinforce the seams and edges to prevent the box from opening during transit.

Label the Package

Clearly label the package with the following information:

• “Keep Frozen” or “Perishable”: This alerts handlers to the nature of the contents.
• “Dry Ice” (if applicable): If using dry ice, include the weight of the dry ice in kilograms and a warning label indicating the potential hazard. The FAA requires specific labeling for packages containing dry ice.
• Recipient and Sender Information: Include the full name, address, and phone number of both the sender and the recipient.
