The foam packaging box itself has a lot of advantages, for example, the density of the product is relatively high. Compared with the original polymer, the density of the microbubble polymer is smaller and the quality is lighter, so that the products produced can achieve better insulation effect, especially if they can reach a certain degree on the thickness. They can ensure that the temperature inside the package is completely isolated from the outside for a longer time.

加上冷藏車的一些應用，存放一些海鮮等保質期更短的產品，也是沒有任何問題的。再有就是這款產品還具有良好的拉伸強度和聚合物的拉伸強度，遠遠的低于與發泡聚合物的拉伸的強度，它們的密度是成正比的，在使用的過程當中不會由于拉扯而發生斷裂的情況，再有就是他們還能夠達到一定的使用壽命，可以反復多次的進行應用是沒有任何問題的。

Coupled with some applications of refrigerated trucks, there is no problem in storing products with shorter shelf life such as seafood. In addition, this product also has good tensile strength and polymer tensile strength, which is far lower than that of foamed polymer. Their density is directly proportional to that of foamed polymer. They will not break due to pulling in the process of use. In addition, they can reach a certain service life, It can be applied repeatedly without any problem.

泡沫包裝箱是一款新型環保的包裝材料，而且泡沫包裝箱它具有質輕、隔熱、隔音、防震等特性，還有很好的防靜電功能，所以泡沫材料使用的范圍比較廣泛。而泡沫包裝箱特有的質輕、隔熱、隔音、防震、耐腐蝕在各個行業都有自己的獨特存在。

Foam packaging box is a new environment-friendly packaging material, and foam packaging box has light weight, heat insulation, sound insulation, shockproof and other characteristics, and has a good anti-static function, so foam materials are widely used. The foam packaging box has its own unique characteristics, such as light weight, heat insulation, sound insulation, shockproof and corrosion resistance.

泡沫包裝箱其中一個有點就是他的隔熱性能很好，一般很多剛出鍋的熟食之類的產品都會用山東泡沫包裝箱蓋好，之前沒有冰箱冰糕之類的東西是需要放到這種泡沫箱子里的。這些產品之所以用泡沫進行包裝，主要是運用了它隔熱性能好，導熱系數低的特點。泡沫箱子的熱氣不容易散失到箱子外面，同時箱子外面的熱氣也不容易進入箱子里面。

One of the foam packaging boxes is that his insulation is very good. In general, many of the products like cooked food and so on will be covered with the Shandong foam box. No refrigerator, ice cream or anything like that needs to be put into the foam box. The reason why these products are wrapped in foam is mainly because of its good thermal insulation and low thermal conductivity. The heat of the foam box is not easy to escape to the outside of the box, and the heat outside the box is not easy to enter the box.

另外泡沫包裝箱子還具有很好的隔音功能，它能夠很好的吸收聲波，從而可以減少反射和傳遞。其次還可以有效的消除共振，達到減少噪音的目的。這類包裝在隔熱和隔音方面都起到了很重要的作用。

In addition, the foam packaging box also has a very good sound insulation function, it can absorb sound waves very well, so that reflection and transmission can be reduced. Secondly, it can also effectively eliminate resonance and achieve the purpose of reducing noise. This kind of packaging plays an important role in heat and sound insulation.
