Foam packaging products are becoming more and more important in the daily packaging of people's production and life. Many manufacturers begin to use foam packaging boxes when choosing packaging boxes. In order to let everyone know more about foam packaging, today weFoam packaging manufacturerLet's take a look at the heat transfer process of foam packaging.

The foam packaging structure measures are different, and the thermal insulation performance mainly depends on the heat transfer coefficient or the heat transfer resistance value of the enclosure structure. The thermal insulation material is combined with the glass insulation board roof of the enclosure structure. The heat transfer coefficient of the directly used composite wall is smaller, and the heat transfer resistance is larger, and its thermal insulation performance is better. The evaluation indexes are different, and the thermal insulation performance is usually evaluated by the heat transfer coefficient value or the heat transfer resistance value. Thermal insulation refers to the heat transfer process in summer, which is usually considered as a periodic heat transfer with a 24-hour cycle. The thermal insulation performance is usually evaluated by the highest temperature value of the inner surface of the enclosure under the outdoor calculated temperature in summer. If the high temperature of the inner surface of foam packaging is lower than or equal to the highest temperature of the inner surface of a brick wall under the same conditions, It is considered to meet the insulation requirements. Materials that can reflect solar radiation heat and enclosure structures are used, and the roof is composite together to maintain an appropriate temperature on the indoor surface to achieve the purpose of insulation.
