Why Choose Thermal Packaging Solutions for your Pharma Packaging?

Here at Thermal Packaging Solutions, we manufacture Insulated Envelopes for Pharmaceuticals. We work closely with Pharmaceutical Companies and the NHS, supplying high performing Insulated Envelopes to ensure the products are protected. We supply to those shipping blood, insulin, vaccines and other pharma products, that need to be protected from excess hear and cold too.

Typically, Pharmaceutical Products needs to be kept between 2 – 8 ºC.

This is why our Insulated Envelopes for Pharmaceuticals solutions are integral to your cold chain management, as we have proven to do this, time and time again – even in the peak of summer and winter.

The Material

Our True Aluminium Foil Insulated Envelopes are manufactured, right here in house in Sheffield.

The beauty of our products is that we only use high quality and highly reflective material and we also would not compromise on the performance. Our Insulated Envelopes reflect a massive 97% of heat transferred, so they boast superior thermal performance compared to other products.

You will notice that we have two different materials for these. The ThermaPack Single material has one layer of True Aluminium Foil and is bonded to an air bubble membrane. The ThermaPack Double instead has two layers of True Aluminium Foil that is bonded to an air bubble membrane. 

You can view more information related to the materials on our ‘Materials’ tab.

Our Insulated Envelopes for Pharma products boast thermal and moisture protection and are also puncture resistant too.

How Do They Arrive?

These are heat sealed at the sides to ensure there is no where for warm or cold air to pass and also to ensure they are robust.

To close the Insulated Pouches, as standard we manufacture these with self-seal adhesive tape. This is for quick closure and also to ensure they are airtight. If you are wanting to reuse your pharma pouches – we can also manufacture these with Velcro seal closure too.

Sizes of Our Insulated Envelopes

Although we list stock sizes of our Insulated Pouches for Pharmaceutical Goods – we can also manufacture any size protective pouch to suit to ensure there is no wasted space.

We appreciate many pharma products can be very small individual items, this is no issue for us – we have the manufacturing ability to meet your bespoke requirements. Please contact us with the dimensions you would like by emailing and we will provide a quote for your specific size. 


If you order stock size insulated envelopes, before 12pm your order will be with you the next working day.

We ship our pharmaceutical packaging solutions nationwide, but also throughout Europe.

If you would like a quote for delivery to somewhere outside the UK Mainland – you can Contact Us directly. 

Customers commonly order our Insulated Envelopes alongside our CoolaPack Ice Pads – which are the cold source.
