Dry ice briquettes<\/strong> are widely used in cold chain transportation to keep frozen food, seafood, and temperature-sensitive products cold during shipping. Unlike regular ice, dry ice sublimates directly from solid carbon dioxide into gas without producing liquid water. This makes it a practical cooling solution for shipments that require frozen or ultra-low-temperature conditions.<\/p>\n\n\n\n

For businesses involved in food distribution, pharmaceutical logistics, and cold chain packaging, understanding how dry ice briquettes work can help improve shipping efficiency and temperature management.<\/p>\n\n\n\n

What Are Dry Ice Briquettes?<\/h2>\n\n\n\n

Dry ice briquettes are compact blocks of solid carbon dioxide (CO\u2082), with a temperature of approximately -78.5\u00b0C (-109.3\u00b0F) at atmospheric pressure. They are available in different sizes depending on production equipment and application requirements.<\/p>\n\n\n\n

Compared with regular ice, dry ice provides much lower temperatures and does not leave meltwater. These properties make it suitable for selected frozen shipments and insulated packaging systems.<\/p>\n\n\n\n

How Are Dry Ice Briquettes Used in Cold Chain Transportation?<\/h2>\n\n\n\n

Frozen Food and Seafood Shipping<\/h3>\n\n\n\n

Dry ice briquettes help maintain low temperatures when transporting frozen meat, fish, shrimp, and other seafood products. When placed inside suitable insulated packaging, they absorb heat as they sublimate, helping preserve frozen conditions during transit.<\/p>\n\n\n\n

Pharmaceutical and Laboratory Shipments<\/h3>\n\n\n\n

Some pharmaceutical products, biological materials, and laboratory samples require very low shipping temperatures. Dry ice can be used when the product’s storage requirements specifically permit it. Validated packaging and temperature monitoring are important for sensitive shipments.<\/p>\n\n\n\n

Temperature-Controlled Packaging<\/h3>\n\n\n\n

Dry ice briquettes can be placed around or alongside products in insulated containers. The required quantity depends on transit time, insulation quality, ambient temperature, and the product’s initial temperature.<\/p>\n\n\n\n

Dry ice is not suitable for every shipment. Products that must remain chilled rather than frozen may require refrigerated transport or another validated cooling method.<\/p>\n\n\n\n
