How Do I Calculate the Amount of Dry Ice for a 12x12x12 Shipping Bag?

To determine the appropriate amount of dry ice, you need to consider multiple factors, such as shipping time, température ambiante, and insulation quality. Typiquement, for every 24-hour period of shipping, tu auras besoin:

• 5-10 livres of dry ice for 24 heures

• 10-20 livres pour 48 heures

• 20-30 livres pour 72 heures

Exemple:

If you’re shipping frozen seafood in a 12x12x12 box for 48 heures, you should plan for 10-20 livres of dry ice to keep the items frozen throughout the journey.

Step-by-Step Calculation:

1. Measure the Volume: UN 12x12x12 box cale 1,728 cubic inches ou 30 litres. This is important because dry ice sublimates based on the volume inside the container, not just the product weight.

2. Duration of Shipping: Calculate the duration in days and multiply by the sublimation rate:

   • 5-10 livres par 24 heures

   • Adjust for longer durations as needed.

3. Qualité de l'isolation: High-quality insulation (Par exemple, panneaux à vide) reduces sublimation, meaning less dry ice is needed. Poor insulation increases the sublimation rate, requiring more dry ice.

What Factors Influence the Amount of Dry Ice Needed?

1. Durée d'expédition

The longer the shipping time, the more dry ice is required. Par exemple, for a 3-day shipment, you will need more dry ice than for a 1-day shipment.

2. External Temperature

Warmer climates cause dry ice to sublimate faster. In hot weather, you’ll need more dry ice to counteract heat gain. De la même manière, pour cooler environments, less dry ice is needed.

3. Type de produit

Some products, comme échantillons biologiques ou aliments surgelés, require more cooling than others. Frozen meats, par exemple, will need more dry ice than cosmetics.

4. Qualité de l'isolation

The better the insulation in your shipping bag, the less dry ice you’ll need. High-quality insulated packaging slows down the sublimation process, helping preserve the dry ice for longer periods.

Exemple:

Expédition médicaments pour 48 hours requires precise temperature control. Pour un 12x12x12 boîte, plan for 20 livres of dry ice to keep the products within the required temperature range.

How Can I Maximize the Efficiency of Dry Ice in Shipping?

To extend the cooling duration and reduce dry ice consumption, follow these tips:

1. Pre-chill the Shipping Bag: Avant l'emballage, chill the bag to reduce dry ice usage.

2. Use Larger Dry Ice Blocks: Larger blocks sublimate more slowly, lasting longer than smaller pieces.

3. Placement approprié: Place dry ice at the bas of the shipping bag to allow cold air to rise and evenly cool the contents.

4. Limit Opening: Opening the bag increases the rate of sublimation. Keep the bag sealed as much as possible during transit.

Exemple:

A business shipping desserts congelés can extend the life of dry ice by using large blocks and pre-chilling the shipping bag.

What Are the Common Mistakes When Using Dry Ice for Shipping?

Several mistakes can reduce the efficiency of dry ice and potentially lead to product spoilage:

1. Underestimating Dry Ice Needs: Always plan for more dry ice than the minimum estimate to avoid undercooling.

2. Improper Packaging: Insufficient insulation can cause dry ice to sublimate too quickly. Always use high-quality packaging.

3. Sealing in Airtight Containers: Dry ice creates carbon dioxide gas during sublimation. Never seal it in airtight containers, as this can cause dangerous pressure buildup.

Exemple:

A business shipping fournitures médicales may mistakenly use too little dry ice, resulting in spoilage of the products. Always overestimate when in doubt.

How Long Does Dry Ice Last in a 12x12x12 Shipping Bag?

The duration that dry ice lasts depends on several factors:

• 5-10 livres of dry ice will last about 24 heures.

• 10-20 livres lasts 48 heures.

• 20-30 livres can last 72 heures ou plus, selon les conditions.

Souviens-toi, higher external temperatures accelerate sublimation. Always adjust the dry ice amount based on weather conditions.
