Explication élargie: Comment fonctionnent les sacs thermiques
Imagine placing a hot beverage in a thermos; the double walled insulation slows down heat transfer, keeping the drink warm. Industrial thermal bags use a similar principle on a larger scale. Multi layer designs combine a reflective outer foil that bounces external heat, an insulation core such as EPE foam or bubble material to trap air, and a food grade inner liner. This construction helps keep contents within a safe temperature range for hours. Some bags also incorporate paper based insulation (CelluLiner), which relies on layered paper pockets to trap air and is fully recyclable. D'autres utilisent foil–bubble composites that provide both thermal and physical protection. Modern industrial bags may feature integrated sensors or pockets for data loggers so you can monitor temperatures during transit, offering transparency and compliance with regulations.
