Fill all void areas remaining inside insulated container with solid dunnage packing material, this improves temperature stability.įor products requiring a LOW-MILD FROZEN profile, general guidelines for extended transit from 10 to 24 additional hours and lower frozen profile include: Surround packed product with frozen cold packs on 2 or 4 sides and place on top and bottom. Varying quality and/or larger insulated containers including larger product pay load will require larger and more cold packs for the number ofĭays in transit. This improves temperature stability and reduces dry ice sublimation.įor products requiring a MILD FROZEN profile, general guidelines for maximum product protection include: Surround product on 2 or 4 sides and on top and bottom. Fill all void areas remaining inside insulated container with solid dunnage packaging material. For the required amount of days to ship, multiply the dry ice per each 24 hours of transit. Dry ice will freeze and keep product frozen. Load dry ice on bottom of container, then load products to ship and cover with dry ice. Varying quality and or larger insulated shipping containers will require more dry ice to cover larger surface area. MILD FROZEN use frozen cold packs FROZEN use frozen cold packs and a little dry ice to extend transit time by 10 up to 24 additional hours.įor products requiring a DEEP LOW FROZEN profile, general guidelines include using dry ice, approximately 5 to 10 pounds for each 24 hours of transit time. A thick-walled EPS polystyrene container will reduce the amount of cold packs or dry ice needed and extend transit times.Ĭhoose the required shipping temperatures for your products.ĭEEP LOW FROZEN use dry ice -108☏ (-78☌). The most important item needed to ship perishable products is a high-quality, industrial, styrofoam insulated cooler with a wall thickness of 1-1/2 to 3 inches.

Consult your dry ice or CO2 gas supplier for more details, and professional advice for your specific situation. CO2 gas is heavier than air, and will drop to low areas and displace air. Always store dry ice in a well ventilated area. Sublimation of dry ice (CO2) gas will cause an airtight container to expand, rupture or burst. DO NOT hold or store in a airtight container or sealed poly bags or glass containers. The thicker the insulation, the slower the rate of sublimation of dry ice (CO2) gas. Depending on the volume stored, the best container for small volume is the expanded polystyrene foam containers, and larger volumes in a rotation molded insulated filled transport container, with an insulated lid or thick quilted top pads. The dry ice snow is compressed and extruded at approximately 1600 psi to form block or pellet form dry ice. The liquid CO2 is released thru a nozzle to 1 bar at which dry ice snow is created. Liquid dry ice is stored at 20 bar and approximately -20☌. Liquid carbon dioxide is the source of dry ice products. Dry ice can only exist at -109.3☏ or (-78.5☌) and maintains this temperature by sublimation. It has an unusual property of subliming, that is transitioning from a solid to a gas, without passing through a liquid phase. Dry ice is a solid form carbon dioxide (CO2) gas and has a freezing temperature at -109.3° F (-78.5☌).
