JB Packaging has been supplying Temperature Controlled Packaging since 1982 and understands the importance of reliable, fast and flexible service. Insulated packaging has come a long way from its roots as a solution for keeping the catch of the day fresh. So you'll find we stock a wide and diverse range of insulated boxes for all your temperature sensitive applications. Our Polystyrene Boxes offer thermal protection like no other packaging material and can sustain a stable temperature under 5°C for as long as 48 hours when your goods are pre-chilled or frozen and our ice sheets are used. As well as our new distribution centre based in Torpoint, we now also have a range of polystyrene boxes that are manufactured and dispatched straight from our site in Livingston, Scotland.
