A general guide for use with Block Dry Ice is: Dry Ice sublimates approximately 3 to 5 pounds per day. The larger the shipment or container, the more dry ice that is generally required. You should surround your product (top, bottom, & sides) for uniform freezing. Pellet, rice & crushed ice requires additional pounds per day, due to it's faster sublimation.

Chilled - Refrigerant Packs
The general guide for refrigerant packs is a minimum of 1:5 to 1:3 pound ratio of refrigerant to product. Larger shipments or containers may require additional refrigerant packs. For best results, surround products for optimum performance during shipping. Special changes may require more less refrigerant packs. Click here to view illustration.
Warming - Heat Sink
Prevent your products from freezing by heating refrigerant packs in boiling water or 'low' heat microwave setting. This is called a "Heatsink", and can be used to ship products in the winter that might freeze in shipment. For best results, surround your product on all side with 68°F or higher warm packs for extended shipping times. Click here to view illustration.
Controlled Temperature Range
The general guide for refrigerant packs cold/warm and frozen is a minimum of 1:3 lb ratio of refrigerant to product. Larger shipment or containers may require additional refrigerant packs. For best results, surround products with cold/warm refrigerants and frozen to the surround cold/warm packs, for controlled temperature performance. For best results we recommend testing to adjust amounts for the desired results. Click here to view illustration.
How to: Choose an insulated container and effectively package your product.
There are many variables to be considered when choosing the container and refrigerant that will protect your product from the weather, elements, handling and vibrations in the distribution cycle.
There are several initial factors to take into consideration when determining how to package your perishable products.
The three most important factors are: insulation, refrigeration and protective packaging. More than just providing thermal protection, you must also provide protection for any rough handling your package endures during shipment. Protective packaging includes internal and external packaging that is used to guard against the elements, rough handling, shock, vibration, compression and aircraft atmospheric pressures.
Refrigerants are the most important component of the perishable product package. When used to surround your product, the refrigerant protects the perishables from the environment. Refrigerants control and stabilize the temperature of the product. The general recommendation is to place ice across the top and around the edges. Please note that although some containers are pricier, they too need a refrigerant to keep the product cold.
CONTAINER THICKNESS
3/4” – 1” EPS foam molded insulated containers are engineered to be from Overnite™ to 2 day shippers.
1-1/2” – 2” thick EPS foam molded insulated containers are engineered for 1 – 5 days transit.
2” – 3” thick EPS foam insulated containers are engineered for 2 - 8 or more days in transit.
CHOOSING THE INSULATED CONTAINER
Arrange the product to be packaged, measure the dimensions (length x width x height). (Note higher is better).
Add 1-1/2” to the height dimension for refrigerant placement across top. Add 3” to width dimensions and 3” to the length dimensions for a 1-1/2” space on either side of length and width to totally surround the perishable product with refrigerant.
For best results place the perishable products and refrigerants into the insulated container. Surround the product with refrigerant.
Fill all void areas (empty space) of the container with dunage or a solid type packing material. This maximizes the insulating performance and prevents products from shifting.

Polar Tech’s EPS packaging products are in fact a Green ” or “Sustainable Packaging” choice.
First, all of Polar Tech’s EPS products are made from an inert material that does not contain or emit any harmful chemicals or gases. Polar Tech’s EPS products do not contain any CFC gases, glues or resins. Consequently, our EPS products can be used and disposed of without any chance that harmful leaching or emissions will occur.
Second, Polar Tech’s EPS products are friendlier to the environment than paperboard equivalents. Available statistics show that EPS packaging products, compared to paperboard equivalents, generate 46% less atmospheric waste and 42% less waterborne waste. In addition, EPS products are produced with 30% less energy.
Third, all of Polar Tech’s EPS products can be recycled. In 2008 alone, over 69 million pounds of EPS products were recycled. That tonnage is sure to grow as companies implement EPS recycling programs. Many companies, such as IKEA and Walmart, are already recycling EPS packaging. With minimal effort, you can too.
In short, there is no environmental reason why you should not continue to enjoy the exceptional cushioning and thermal insulating properties of Polar Tech’s EPS packaging products.
