Controlling the temperature of packages is crucial when it comes to shipping temperature sensitive goods, such as pharmaceuticals and food products, but is dry ice actually the best way to control the temperature inside your packages throughout the delivery process?

Dry ice has the ability to control the temperature of packages, but so do water ice packs and gel ice packs. It is important to establish which temperature controlling option is the best for your products and packaging.

Dry Ice

Dry ice is a solid form of carbon dioxide that sits at a temperature of -79 degrees Celsius. It can stay cold for a very long time and can be a good option for shipping frozen products.

  • When dry ice thaws, it does not melt into a liquid, but instead turns back into a gas, so it does not get any products or shipping packaging wet.
  • There is no secondary waste when it comes to dry ice because it turns into gas.

That said, it’s also important to know that dry ice has its downsides.

  • It can’t be used to ship items that should remain chilled, because it is too cold and will freeze them.
  • Not only that, food shipped with dry ice should be 100% sealed because it can alter the taste and texture of a product.
  • Dry ice can also be dangerous to touch without the correct protection and it should never be handled with bare hands. Packages containing dry ice should also have hazard labels applied to the outside to explain to those handling the packaging that it contains a hazardous material.
  • There are also more forms to fill out when using dry ice for transport, which can increase the handling charge.
  • In recent months there has also been a shortage of dry ice, due to the shortage of carbon dioxide (the gas used to make dry ice). The shortage of CO2 and dry ice has caused big supply issues for lots of businesses that rely on CO2 to keep their products frozen during shipment.

HydroFreeze Ice packs

Ice packs, such as HydroFreeze and HydroFreeze+ have the ability to offer a safe way to deliver frozen and chilled goods with none of the negative associations that dry ice brings.

  • HydroFreeze ice packs are completely food contact safe so will not alter the texture or taste of a food product, unlike dry ice. This also applies to all ice packs in the Hydropac range.
  • They are FSA certified food safe, non-toxic and not classed as hazardous goods
  • They have a burst strength of over 200kg.
  • They can be tailored and printed with a company logo for a professional appearance.
  • Unlike dry ice, they require no special safety handling guidelines or external labels.

Dry Ice vs Ice Pack Comparison

Overall, when handled correctly, dry ice can be a good product to use, but it is currently at a nationwide shortage and requires several added steps when shipping, such as handling safety, storage and disposal and regulatory considerations.

Ice packs are beneficial for temperature sensitive products, more cost effective (especially with the CO2 shortage) and ultimately safer for the products and those handling the packaging. Available in both freezer trays and courier boxes, Hydro-Freeze ice packs give you the benefits of dry ice without the risk.
