Why Choose Dry Ice Packaging for Shipping Perishables?
Dry ice packaging provides a simple and reliable way to keep cargo extremely cold while avoiding the mess associated with melting ice. Dry ice does not melt; it sublimes directly from a solid into carbon dioxide gas. This means shipments remain dry, with no water pooling in your box or cooler. When used correctly, dry ice packaging maintains temperatures as low as – 109 °F (approximately – 78 °C) for hours or even days, dependiendo del aislamiento.
How Does Dry Ice Packaging Work?
Dry ice packaging uses an insulated container lined with material that allows the carbon dioxide gas to escape safely. The dry ice inside gradually sublimates, absorbing heat from your products and maintaining low temperatures. Containers are usually made of expanded polystyrene foam (Espuma de poliestireno) placed within a corrugated cardboard box. This dual-layer design provides strength and insulation while allowing ventilation.
En contraste, traditional ice melts and creates liquid water; gel packs absorb heat and eventually become warm. Dry ice packaging keeps items below freezing for longer, haciéndolo ideal para:
Alimentos congelados: mariscos, carne, helado, meal kits and specialty baked goods benefit from sub-zero temperatures during transit.
Life sciences: vacunas, diagnostic specimens and pharmaceuticals often require shipment between – 70 °C and – 20 °C.
Industrial applications: shipping biological materials or lab reagents that must remain frozen.
What Are Dry Ice Pack Sheets and How Do They Differ from Gel Packs?
Dry ice pack sheets are flexible sheets containing pockets of dry ice or dry ice compound. They offer similar benefits to loose dry ice but are easier to handle. El sheeted design reduces direct contact with skin, which helps prevent frostbite, and it simplifies packing because you can cut the sheet to size.
Gel packs are reusable polymer-based packets filled with water or another cooling gel. They maintain temperatures around 0 °C and gradually warm to ambient temperature. A diferencia de los paquetes de gel, dry ice pack sheets maintain sub-zero temperatures and produce no liquid by-product. They are suitable for shipments requiring extremely cold conditions over shorter durations or where space is limited.
Choosing the Right Packaging: Factores clave
Product type and temperature requirements: Know the critical temperature range for your product. Por ejemplo, vaccines shipped on dry ice may require – 70 °C, while gourmet pastries may only need to stay below – 18 °C. Dry ice packaging and pack sheets are designed for ultra-low or low-frozen temperatures, whereas gel packs cover refrigerated ranges.
Tiempo de tránsito: Estimate how long the shipment will be in transit. El hielo seco se sublima con el tiempo; plan the quantity to last the entire journey plus a margin.
Regulaciones: Dry ice is a hazardous material classified as a Clase 9 dangerous good with UN 1845. You must comply with shipping regulations including labeling, packaging and documentation.
Budget and sustainability: Consider cost per shipment, waste disposal and environmental impact. Dry ice is made from recovered carbon dioxide, but the manufacturing and packaging produce emissions. Reusable gel packs may be more economical for frequent shipments at moderate temperatures.
What Safety and Regulatory Guidelines Must You Follow?
Shipping dry ice requires knowledge of regulations and safe handling to protect workers, carriers and recipients. Los EE. UU.. Departamento de Transporte (PUNTO) y la Asociación Internacional de Transporte Aéreo (IATA) set strict guidelines for packaging, etiquetado y documentación.
Hazard Classification and Training
El hielo seco está clasificado como Clase 9 miscellaneous dangerous good. Its proper shipping name is “Dry Ice” or “Carbon Dioxide, sólido,” and its UN identification number is Y 1845. Employees handling dry ice packages must receive hazardous materials (patria) training to ensure they understand the risks and procedures.
Dry ice shipments are regulated because they:
Create pressure: Mientras el hielo seco se sublima, carbon dioxide gas builds up. Containers must allow gas to vent; de lo contrario, they could explode.
Displace oxygen: Carbon dioxide is heavier than air and can accumulate in confined spaces, posing a suffocation hazard. Ensure there is ventilation during storage and transport.
Cause cold burns: Dry ice sits at around – 109 °F. Contact with skin may lead to frostbite.
Requisitos de embalaje
Labeling and marking: Packages must display the proper shipping name, Número de la ONU, la clase 9 etiqueta de peligro, and the net weight of dry ice in kilograms. Each package must be clearly marked with the shipper and recipient addresses and include a declaration that carbon dioxide gas will be released.
Límites de peso: Para transporte aéreo, the net weight of dry ice per package is often limited to 200 kilos (check your carrier for specific limits). Too much dry ice can create excessive pressure.
Documentación: An air waybill or commercial invoice must list the UN number, número de paquetes y peso neto. When shipping internationally, include import/export permits and other required documentation.
Packaging materials: Outer packaging should be durable and leak-proof. Use fiberboard or wooden boxes with insulation such as expanded polystyrene. Avoid sealed containers or materials that become brittle at low temperatures.
Ventilación: The package must allow carbon dioxide gas to escape to prevent pressure build-up. This often means leaving a small vent or using containers designed to vent gradually.
Handling and Safety Tips
Equipo de protección personal: Use guantes aislados, goggles and face protection when handling dry ice. Use tongs or tools to avoid direct contact.
Ventilación: Work in a well-ventilated area to prevent carbon dioxide accumulation. Do not use dry ice in confined spaces such as car trunks without ventilation.
Almacenamiento: Store dry ice in insulated containers but do not seal them; sealed containers may explode. Keep away from children and pets.
Desecho: Let leftover dry ice sublimate in an open, ventilated area. Nunca deseche el hielo seco en los lavabos, toilets or trash bins.
First aid: Treat frostbite caused by dry ice like a burn—warm the area with lukewarm water and seek medical attention if needed.
Following these guidelines protects you and ensures your shipments comply with regulatory requirements.
