| General Guides for Packaging Perishable Products
Frozen - Dry Ice Shipments:
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 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 its 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 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 "Heat Sink", and can be used to ship products in the winter that might freeze in shipment. For best results, surround your product on all sides with 68°F or higher warm packs.

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. |
