Before we start how to select cooler bag, we should understand how the cooler bag keep warms or cold. Many cooler bags could be found are made of foil aluminum foil, PE foam, oxford. Why the manufacturer use this material but not other material?
The thermal conductivity of the aluminum foil insulation coil is relatively low (about 0.035), and the sealed environment blocks the contact with the air, so that the temperature inside is concentrated in the bag and cannot be directly dissipated, which prolongs the time of temperature loss in the bag. It also achieves the purpose of heat preservation.
Oxford cloth is characterized by high density, light weight, waterproof, abrasion resistance, non-toxic, good elasticity and strong heat preservation.
2. Keeping warm time
1. Generally keeping warm time
Bag warms is another purpose what the buyer seeking for too, we are now discussing keeping warm time: food in an insulated bagwarm should be still warm after three to four hours if it’s hot, For keeping cold time: eight to 10 hours if it’s cold, if adding a frozen gel pack can buy you three to four extra hours.

Some seller will exaggerate the heat preservation time of refrigerated bags, generally the heat preservation time is 2-5 hours. If you see the heat preservation for 48 hours, you must choose carefully. See if it takes time to add ice packs to avoid being misled.
