We`re Polar Thermal


Polar Thermal Packaging Ltd manufacture a range of temperature control insulated systems. They include transport packaging for blood products, food, vaccines, pharmaceuticals, fine chemicals and many other specialist applications. Our entry in to the thermal control market came following a request by the Ministry of Defence to solve the problem of frozen food melting at the dockside. Since then our CEO Paul Harrison and the team, have put their design skills and entrepreneurial flair to good use, making applications for the National Blood Service, Van den Berg Oils, DHL, Excel Global Logistics, Marks and Spencer, Tesco’s, Sainsbury’s, Astra Zeneca and Pfizer to name but a few.

Our primary target markets are Pharmaceutical, Clinical Research Organisations, Health Service Providers, Perishable Food Distributors and Logistics Companies, although our range of unique products are easily transferable to many other industries and service sectors.

We believe we have the best performing British product in its field, and all our products are manufactured at our Wiltshire based factory. All systems are reusable and have a two year guarantee.


Our products are now used throughout the world – we are continually exploring new markets and seeking partners that share our vision. If this is you then please get in touch!


In recent testing by NHS England our products scored 100/100 – our closest competitor scored 87. Why? Because whilst many products may be made to look like ours they do not use the same materials nor do they have our British workmanship


Our products have been deployed in the harshest and most testing environments and proved themselves – whether it is constant daily use in UK hospitals or in conflict-zones like Afghanistan you can be assured of effective and durable service.

Space industry behind new insulating blanket

The new Polartherm insulating blanket owes its origins to the US space programme.

Independent trials at Cambridge Refrigeration Technology’s proving labs have shown that Polartherm material has the best thermal insulating profile in its class, revealing a thermal conduction value of 1.19W/m K.

For the air freight industry, the company supplies high integrity liners for LD3, LD7 and LD9 configurations that are collapsible and reusable. These passive liners offer an alternative to other more bulky, battery-powered systems.

Currently, supermarket clients are shipping fresh produce to Dubai and Hong Kong from the UK without additional temperature controls. Cold blocks may be used for extended thermal performance, but typically a LD3 container will maintain 2-4⁰C for 32 hours in ambient temperatures of up to 35⁰C.

For pallet loads, the Tranzcube is a versatile cover offering a lightweight insulation jacket and a high density, lightweight rugged, poly pallet base, bringing immediate benefits to the storage and transportation of frozen, chilled, hot or ambient products. In tests with the Royal Navy, such covers have kept a pallet of 22⁰C frozen foods at a stable temperature, with minimal loss of 4⁰C over a ten hour journey at an ambient 30⁰C.

Light Weight Pallet Shipper

See here in our test facility undergoing pre -production temperature testing is our new PolarLite, one trip and recyclable integral pallet shipper.

Weighing in at just under 20 Kg. PolarLite is self stacking and offers enormous weight advantage over bulky, powered insulation systems for air or road transport.

Dimensions: H. 1.5M, suitable for Euro pallet format, Imperial or US specs. Weight Limit up to 800Kg

Tested Temperature profile: 30 Hours in+30° C ambient, 2-8° C contents.

LD3 Air Shipper,One Trip Foil Liner

Ideal for those shipments requiring temperature control with disposability, the new, lightweight PolarFoil, One-Trip LD3 liner will fit the bill., the liner is quick to erect and is self sealing. Temperature profile: 30Hrs at +30 Deg.C , contents kept at -2 to -4 Deg C


LD3 Cargo Liner , Now major Upgrade

The latest LD3 is a totally new design and upgrades one piece system, which is self standing and has just the one door with zip closure.

These latest LD3 Polar Thermal blankets will protect produce 2C to 8C for 72 hours in +30C.

It’s a one piece system, with many upgrades and features that assist with an increased performance of upto 72 hours 2C to 8C .The system is self standing inside the AKE Bin, and for reverse logistics, six can be returned inside one bin

Internal fitments can accommodate gravity feed to waist level, or any specific dispense arrangement.

It is ideal for ambulatory vending at events or in support of fixed sales outlets, as well as sampling at railway stations or in a retail situation.

Tests carried out at the laboratories of Cambridge Refrigeration Technology, show that Polartherm had the best insulation properties in its class.

The temperature profile of the backpack will keep ice cream at -18° for at least 6 hours. The carrier is easily cleaned and complies with food regulations.

Polarthermal can design and manufacture any style required in either long or short runs. Logos and designs can be screened on to the pack in corporate colours.
