Temperature is a critical factor when shipping frozen foods. Because there are many elements that you won’t be able to control once your package is on its way, you should plan its insulation correctly. With sufficient insulation, you could minimize quality loss during shipping and ensure customer satisfaction.

Here’s what you need to know about transporting frozen foods.

Importance of Insulation

Perishables and frozen goods are exposed to harsh conditions during shipping. Humidity, heat, handling of packages, and shipping time could affect the quality of your products.

Insulation is important in transporting frozen goods as it prevents heat transfer through the container walls. Proper insulation extends the life of your frozen goods by preventing thawing during transport. It also protects your goods from the effects of sudden temperature variations, which often happens during shipping and handling of your packages.

Keeping Frozen Foods Frozen During Shipping

Perishables and frozen foods have different temperature requirements. For instance, frozen foods must maintain a temperature of zero degrees Fahrenheit at all times while refrigerated foods should maintain a temperature between 32 degrees and 60 degrees Fahrenheit.

When preparing goods for shipping, make sure they are frozen. Keep them in the freezer while you prepare the container and only take them out when you’re ready to pack them. You’ll need a watertight bag to line the box for transport, ensuring no liquid will seep out of the box. For additional protection, have another bag to put your frozen goods in. This way, if the first layer of protection fails, you have another layer protecting the container or box from being damaged.

The amount of refrigerant you need to use would depend on how big your container is. Ideally, you should have enough refrigerant to put around and on top of your frozen goods. If there are still spaces around the container, you could fill them with loose fill packing peanuts. This could work as an added protection or cushion for your frozen goods during shipping.

Why Use Dry Ice

You could use different types of refrigerants for shipping goods but the most popular and recommended option for frozen foods is dry ice. Gel refrigerants are great for perishables and chilled goods. However, it might not be able to maintain the temperature requirement for frozen goods.

Dry ice is perfect for transporting frozen goods, as its cooling capacity is three times more powerful than regular ice. Additionally, because it doesn’t turn into liquid, you won’t have to worry about your goods and the container getting soaked when they reach their destination.

How to Ship With Dry Ice

Despite being popularly used for shipping frozen foods, dry ice is considered a hazardous material. Therefore, you should be careful in handling and packaging it along with your products.

Once you’ve placed your goods and dry ice inside the container, be sure not to completely seal the liner bag. Dry ice turns into carbon dioxide and it needs space to vent. Close the bag but don’t make it airtight. Otherwise, pressure could build up inside the container and it could burst. Use a pressure-sensitive tape to secure the seams and flaps of your container.

Inform your shipper that you are transporting a package with dry ice. They’ll require you to label your box accordingly. Make sure that the markings on your container are legible and visible. It should have “dry ice” on it, together with its net weight (in kilograms).
