I used this for insulation when delivering food from my restaurant to distant locations. Compared to regular foam, it's compressed and quite hard and durable. The restaurant has closed, so I'm selling it since I have no use for it anymore. I think it can also be used privately as a large cooler box. Here's the product description (quoted from the website): ● Made of highly compressed foamed polypropylene, it is lightweight yet sturdy, and is characterized by its resistance to chipping and cracking. Also, the solid foam absorbs impact energy from the outside and quickly returns to its original shape. ● The heat resistance is up to 120°C, so it can be washed in a dishwasher. It can be used repeatedly in a hygienic manner. It is water-repellent and has excellent water resistance. ※The heat resistance of the GN1/1 Faltbox is up to 90°C. ● The front loader and GN series comply with the Gastronorm standard. Efficient storage and transportation using hotel pans is possible. ● Boasts a sufficient heat resistance of -40°C to 120°C. ※GN Faltbox -30°C to 90°C. ● Made by Bartscher, Germany. #CoolerBox #Insulation #LargeCoolerBox
