Cooler bag is also called a lunch bag, which is popular among students, white-collar workers and outdoor sports enthusiasts because of their function of keeping the temperature.
The main functions of a cooler bag are as follows:
The insulation principle of a cooler bag is not to create a heat source, but to isolate the inside of the bag from the material used on the outside. If it&#;s summer and you have cold drinks and ice in your cooler bag, the cooler bag will insulate the outside heat source from entering the bag, so as to achieve the effect of keeping a low temperature in the bag. On the contrary, if it&#;s winter and the cooler bag is filled with a hot meal, the cooler bag will insulate the cold outside and keep the bag hot inside.
Therefore, the main factor of the insulation effect of the cooler bag lies in the thickness of the insulation material, the number of layers and the sealing process. The insulation structure of the cooler bag is generally four layers:
PEVA and aluminum film are the two most commonly used materials for the interior of cooler bags, both of which have the effect of insulation and moisture resistance. PEVA and aluminum film of the same thickness have different performances in thermal insulation effect, easy cleanliness and cost.
The most important function of a cooler bag is insulation. If a cooler bag is poor even with the most basic insulation function, then there is no need to buy it. Then how to choose the good insulation effect of a cooler bag? It has been summarized above that the insulation effect of thick insulated cotton and a well-sealed cooler bag is the best.
According to different requirements, the capacity requirements for the cooler bag are different.
Students who bring their lunch boxes: 5L
Student cooler bagWhite-collar commuters: 6-7L
Cooler bag for workOutdoor enthusiasts: 8-15L
Cooler bag for exerciseThe mommy who takes the kids on a picnic: 7-8L
For outdoor enthusiasts, the load-bearing effect of a cooler bag is an important indicator to consider. Imagine a day&#;s camping trip. How much food do you need to pack? How much does the food weigh? Of course, if you plan to be outdoors for more than a day, the cooler bag may not be enough, and you need to use an oversize incubator.
A good-looking cooler bag is often more favored by consumers. Most of the cooler bags with high sales volume have a beautiful appearance or pattern with a good color scheme. The cartoon-patterned children&#;s lunch bag is the most popular among kids.
The cooler bag with excellent storage structure not only has an insulation space but also has storage spaces. Hot food or cold drinks placed in the insulation space for a long time will certainly have water vapor, then the carried thermos cup or paper towels will be damp. A separate storage space would solve the embarrassment.
