Keeping the temperature below 10 degrees can last more than 12 hours, which is related to the refrigeration effect of ice packs, thick foam and 2 cm thick foam.
The density of the inside of the box and foam box is 0.0138 cubic meters, and the room temperature of 24-30 degrees is related to the ambient temperature.
Freezing time depends on the thickness of the foam box, the number of internal ice cubes, and the tightness of the box. Take the foam box, usually 3
Not much work that day.
Foam boxes mainly depend on density, size and insulation properties. The higher the density, the thicker the thickness, the better the insulation performance and the longer the insulation time.
It is also relatively long.
If the delivery can be frozen, it is best to freeze it in a foam box and place it in a cold storage bag.
Warm much longer.
