Author:Zhongshan Sedagon outdoor products Co., Ltd Click: Time:2022-06-14 09:09:01

Cooler bag has different thermal insulation and ice preservation effects due to different thermal insulation cotton. This test is carried out by cooler bag factory of sedagon waterproof bag factory.



As shown in the above figure, on the left is the Coca Cola 12L ice bag (the insulation cotton is 22mm thick NBR insulation cotton), and on the right is the trademark free 12L ice bag (the insulation cotton is 22mm thick EPE pearl cotton).


This is the photo taken from 9:00 yesterday to 8:50 this morning when the same weight of crushed ice was loaded.


It can be seen that the surface of the ice bag on the right is frosted, indicating that the cold and heat exchange rate is fast, while there is little change on the left.



Open the bag cover and see the comparison of the overall effect. The ice on the left melts less and the ice on the right melts more obviously.



Close up, the contrast is obvious.



Due to the frequent hot and cold exchanges on the right side, some of the stools he inquired about were wet.




Zoom in photo on the left.



On the right, the frost is serious.


Preliminary conclusion: NBR cotton is superior to EPE pearl cotton under the same model and condition.


Of course, continue to observe the effect difference tomorrow.



This test was carried out by sedagon waterproof bag factory and cooler bag factory.
