In all, it tool Woolcool three years to develop LifeGuardian. Unlike standard cooling boxes made from airpop© (formerly polystyrene), the insulation material in LifeGuardian is completely wool-based. The new packaging material allows the transportation and storage of sensitive active ingredients at 2-8°C for up to 150 hours without any detrimental effect. This is twice as long as the current standard period of 72 hours for the cooling of drugs, says the company.
This precise temperature control is made possible through artificial insulation of the wool. Perforation within the inner protective film increases the oxygen exchange of the wool, thus warranting a sufficiently cool temperature of the packaged product. Compared with thermal packaging made from polystyrene, a LifeGuardian box is a quarter of the size and half its weight, while also providing 25 per cent more space for the product.
As well as insulated packaging for pharmaceutical products, Woolcool also makes boxes for the transportation of fresh food. Meat and organic products, in particular, can thus be transported and stored below 5°C for up to 48 hours without compromising quality.
