An introduction to
Cold Packs
An introduction toThe burgeoning demand for temperature-controlled products to be moved safely around the globe shows no sign of letting up; the growing needs of the middle classes in many emerging markets and the rapid development of biopharmaceuticals have both been key contributors.
Perishable goods like a whole gamut of chilled and frozen foods, wine, flowers chemicals, pharmaceutical and biological products, all need shipping reliably. As a consigner, to meet regulatory compliance and maintain products at either frozen, chilled or ambient temperatures, you essentially have the choice between packing your temperature-controlled shipper using dry ice or cold packs.
While cold packs are generally acknowledged to be the primary choice for maintaining temperature-sensitive shipments at refrigerated or ambient levels, dry ice is often deployed where frozen goods are concerned. However, as it gives off CO2 during sublimation, dry ice is viewed as a hazardous substance and is subject to labelling, handling, storage, shipping and disposal complications.
The Tempack range of cold packs offers a host of reliable, safe, high-performance alternatives. Our pre-qualified cooling packs come in flexible and rigid systems, ranging from the inexpensive to the smart. Each can sustain a specified temperature range for an extended period to preserve the integrity of a temperature-sensitive consignment.
Rigid Cold Packs/Plates
The robust, resistant solution for refrigerated transport
A combination of high-density polyethylene (HDPE) and eutectic gel form the backbone of the Tempack Rigid Cold Pack. Offering incredible resistance to breakage and compression, this tough, recyclable plastic exterior holds a eutectic solution that absorbs heat and ensures a more stable temperature release. Together they enable temperature-sensitive products to remain at refrigerated temperatures throughout their cold chain journey for up to 120 hours.
Rigid Frozen Packs/Plates
The solid, safe dry ice substitute
As a viable alternative to dry ice which carries regulatory burdens due to its hazardous CO2 composition, Tempack’s Rigid Frozen Packs offer safety, strength and peace of mind without the logistical headaches. Utilising the rigidity of HDPE as a container, the eutectic gel in this product upholds negative temperatures, with phase change in these frozen packs occurring at -21ºC. Autonomy extends up to 4 days. The product is also environmentally responsible and is fit for reuse and recycling.
Flexible Cold/Frozen Packs
The easy, economical cold pack
Tempack’s flexible cold/frozen packs represent a more economical alternative to traditional cold packs. Lighter and easier to use, their high calorific capacity prolongs refrigeration time due to extremely low heat conductivity. Being non-toxic, heat-sealed and resistant to damage, these temperature-controlled cooling packs are suitable for contact with food and will protect perishables in their correct state for up to 48 hours. They are available in different sizes and weights.
