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.

Polar Thermal Vaccine Bags

Advanced Developments in Vaccine Transport

Vaccine Transport, a critical area at home and overseas whether by air or road 

Our popular range of Vaccine Bags has been extended at the request of a number of NHS Trusts to include a convenient 3 Litre bag and a universal 75 litre unit.

These now complement our standard range of 10, 20, and 30 litre carry bags which are ideal for static or peripatetic vaccination programs.  lasting up to 8 hours with a minimal loss of 0.74°C per hour with the product put in at 2°C and the lid left unopened! 

An inner lid reduces thermal leakage, helping to maintain temperature parameters despite repeated opening of the bag.  Developed using NASA technology our Polartherm™insulation is made up of an inner reflective layer, a hollow fibre filler material, that is both tough and lightweight, with excellent thermal control properties.  


Every square meter of Polar insulation, is produced from over 600 recycled plastic bottles. 

The Vaccine Safety Pack – Thermal Pillow, coolants and separators

Polar, through NHS testing, advise the use of 5°C cool packs to help maintain temperature,  using these at top, bottom and sides. These together with our thermal separators give greater added protection should the bag be opened often.   A thermal pillow fits snugly on top and is moved down as vaccines are dispensed to maintain the temperature of the remaining units.

These “Vaccine Safety Packs” can be bought as part of the system, or separately – they are available of all Polar Vaccine Bags.

Nurse’s Clam Shell

The Nurses clam shell bag , designed for care in the community, along with thermal vaccine carriers, have been designed to maintain a temperature of between a 2° to 8°C for up to 8 hours, especially for use with vaccination programmes or specimen collection. 

PolarThermal in Innovation Award!

Clive Lawrance, long-term associate of Polar Thermal and MD of Omnia Management winner of the 1st Cool Logistics ‘Innovation in Perishable Logistics’ Award

LONDON, 19.09. 2019 Clive Lawrance, Omnia Management, was announced yesterday as the winner of the 1st Cool Logistics ‘Innovation in Perishable Logistics’ Award at the 11th Cool Logistics Global Conference in Valencia.  The winner of the award was selected by an international panel of stakeholders with an interest in furthering perishable supply chain excellence. Omnia Management was recognized for its contribution and adding value to the cold supply chain.  

Omnia Management has set the standard for innovation in the cold supply chain “It was a great honour to receive the award at Cool Logistics Valencia.  True recognition of my Shortest Route to Market using innovation to remove outer packaging in the Logistic supply chain” said Clive Lawrance, Omnia Management.

Omnia Management implemented a packaging project in three countries, working with growers and major retail importers.  Polar Thermal covers were used to maintain fresh produce temperature integrity throughout the supply chain instead of typical packagings such as cardboard, plastic or polystyrene. This reduced wastage at the point of destination. Straight-line temperatures were maintained throughout the journey of the fresh produce together with significant cost reductions in packaging and waste disposal.  Reducing waste packaging waste is an issue of global interest, and in this case, the waste packaging reductions were achieved in the air freight cold chain.  Packaging, reducing waste and the use of plastic packaging have been major themes through Cool Logistic Global 2019 so the judging panel was delighted to recognize and acknowledge the importance of Omnia Management’s initiative

The Award was kindly sponsored by Martico, a leading freight forwarder. Specialists in the management of any type of load at controlled, refrigerated or frozen, Martico covers the entire logistics chain and exports and imports reefers by sea, land and air.

Getting Greener

Polar Thermal is known for its ethos of reuse whenever possible, but we are looking to back our commitment to the environment in every project we take on.

Paul Harrison, CEO of Polar, is widely respected for his stance on sustainability without reduction in performance, and believes that we are entering into an exciting phase – the methods and mantra he has been pushing for years are now coming of age.

Currently we are developing a number of “last mile” solutions that will make a big contribution to ethical deliveries, but we should also remember that the PolarTherm™ Fibre that is a core component of many of our systems is mainly produced from recycling plastic bottles – 20 are used for each kilo of fibre.

We are also interested in using material produced from recycling plastic in the ocean – in Spain, Ecoalf have already recovered over 400 tonnes since 2015 – at Polar we look forward to incorporating even more sustainability into our products.

Polar Ethos

Paul Harrison – MD

At the TCS&D Show Paul Harrison talks to Media Studios about the ethos of Polar Thermal and how that translates to the design, development and manufacturing at their UK factory in Warminster.
