Bespoke Packaging
If you are looking for something a little more individual to make you stand out from the crowd, Soken can organise bespoke packs for you. Just give us a call and we can take care of the rest.

Additional Tooling
As manufactures of all our own heat sealers, unlike others, Soken don’t tie you in to one specific range of packaging. Our focus is ensuring you have the equipment and tools to seal the packs what you want. Should you wish to change or diversity your product range or packaging at any time in the future, Soken will support you with additional tooling as you grow and adapt your sealing requirements.


Over the last couple of years our in house sandwich kitchens have grown. As a food business the quality of the products that we serve to our customers each day is very important to us. The Soken HS35A sandwich sealer has helped us improve production efficiency, product quality and is a very reliable piece of equipment that we just couldn’t function without.

Having worked with Soken Engineering for more than 15 years now, I have always found their equipment and service to be first class and highly recommend them.

Soken machines are built to last, we chose to go with them for their speed, reliability and performance of the machines in general. We purchased not 1 but 2, an HS52 & HS60 model. They are great robust machines that will do the job you want.
