Heat-preserving bag is an excellent option for holding a considerable amount of food items. Its outer layer is crafted from sturdy 840D polyester fabric, coupled with a thick insulation layer, a heat-resistant liner, a smoothly-operating zipper, and a non-harmful foam base. These elements work in unison to guarantee that your food remains safe and maintains the desired temperature as necessary. The bag is highly flexible and appropriate for food delivery on scooters.
