About Us

We have been at the heart of the medical devices industry for many generations. Our journey started in Sheffield, UK way back in 1601 and over the years our family owned business has evolved from producing many forms of cutlery to knives, scissors, tuning forks, razor blades, surgical instruments and surgical blades. It was surgical blades that got us into medical packaging and we were amongst the pioneers of the first sterile packs for single use blades back in the early 1960’s. These days our business is all about medical device packaging.



Granton Medical has been a proud member of The Sterimed Group since January 2023.

The Sterimed Group, headquartered in France, is a global leader in medical packaging, servicing medical device manufacturers and patient care facilities. We develop and deploy an innovative solution that aligns with our customers’ toughest challenges, requirements, and expectations.

Sterimed is the only player in the world of medical packaging which can manufacture multiple types of sterilisable materials and convert them into ready-to-use roll stocks, pouches, header bags, sterilisation wraps, and many types of pre-made products for a safe sterilisation process. Sterimed operations address global needs with production and logistics facilities in the Americas, Europe and Asia, offering a fast supply of highly reliable materials manufactured in 100% dedicated premises.

Our first experience of medical device packaging came in the early 1960’s when we were amongst the pioneers of the first sterile packs for single use surgical blades, using Cobalt 60 Gamma Irradiation. In the period from the 1960’s to the 1980’s we developed our own in-house specialist packing lines for the packing of sterile surgical blades.

In the late 1990’s we started to manufacture Self Seal Sterilisation Pouches, initially for the dental market, using unique, high-speed, fully validated plant, and since then we have grown into the UK’s largest volume manufacturer of these products.

In the early 00’s we went on to launch a sub-contract packaging service to the medical devices industry. Now known by the name Cleanline® we offer an almost infinite range of customised turnkey packaging solutions that meet the demands of our customers in the medical, dental, orthopaedic, podiatry and other challenging arenas. From cleanroom hand and machine packing, right through to thermal washing and disinfection, our services play a critical part in the commercial success of the customers who use them.

In recent times, we have commissioned and installed a 6-colour flexographic printing press at our premises in Sheffield, enabling us to print all our own sterilisable packaging materials in-house and to supply the medical devices industry with printed sterilisable rollstock packaging materials.
