Polyurethane has low thermal conductivity (0.025 W/mK). This form of insulation ensures that products are transported in complete safety on long distance and international journeys. It is highly effective and economical in use.
It is also a flexible material, easier to process than polystyrene. It can be moulded into shapes to suit specific requirements. This means that polyurethane can be used to manufacture specially-designed insulated packaging solutions.
The term ‘payload’ denotes the ratio between the quantity of products transported and the total weight of the temperature-controlled packaging. At Sofrigam, this ratio is of particular importance, with packaging solutions that are 35% lighter than those of our competitors. “With a similar external size and equivalent performance, we offer insulated shipping packaging solutions with 20% greater payload”, asserts Laëtitia Perche, Group Marketing and Communications Manager. This is explained, in particular, by the use of polyurethane.
In addition, the accessories supplied with the containers to ensure that they are easier to use reduce the preparation time by up to 50%. This is a significant contribution to optimising cold chain logistics!
We encourage three-way collaboration between laboratories, logisticians and the suppliers of packaging solutions. Genuine collaboration ensures that packaging solutions are adapted to suit actual logistical requirements. “It is up to the logistician to ensure that the package is delivered in satisfactory condition within 48 hours. We also encourage the laboratories to place sensors in their containers in order to ensure that the temperature profiles they have requested from us are consistent”, notes Laëtitia Perche.
These 3 factors allow us to guarantee the design and manufacture of efficient and inexpensive insulated packaging solutions. However, they are of little use without a strategy for the continuous improvement of manufacturing skills: our staff are working on this aspect!
