                                                                                                                                                  蘇州泡沫箱是一種用泡沫(多孔塑料)制成的箱式包裝容器,其內部是有許多細小氣孔的塑料泡沫。泡沫箱經常用來運送水果和包裝物品。但隨著冷鏈物流的發展,不少消費者發現自己所訂購的生鮮食品也是用泡沫箱包裝,不少消費者對此表示好奇:泡沫箱能保溫嗎?隔熱期有多久?

                                                                                                                                               

                                                                                                                                                  EPS發泡箱就是一種很好的包裝材料,EPS發泡箱可以作為電視、冰箱、洗衣機、空調、電子儀表、精密儀器、玻璃制品、陶瓷制品、美術制作等產品的緩沖包裝。以聚苯乙烯樹脂為基料,加入發泡劑及其它輔助材料,通過加熱發泡制成EPS泡沫塑料。本發明的特點是重量輕,導熱系數小,吸水能力小,耐老化,耐低溫,容易加工,價格便宜,質量好。包裝物較易回收再利用,是優良的綠色包裝材料。

                                                                                                                                               

                                                                                                                                                  專家們表示,泡沫箱可以同時保持低溫和保溫。泡沫箱保溫的原因是泡沫箱本身的傳熱性能較差,泡沫箱內含有大量空氣,而空氣的運動又極其受阻,加上泡沫箱內的微孔阻止空氣流動所形成的“對流熱傳導”,使得泡沫箱保溫效果極佳。泡沫盒的保溫時間取決于盒的厚度、冰塊數量、保溫層數量。若冰的體積相當于被隔熱材料的體積,泡沫盒厚度約3cm,隔一兩天就可以了。

                                                                                                                                               

                                                                                                                                                  泡沫盒能長時間保持食品的新鮮,防止食品在貯存中失去原有的鮮味,但為了保證良好的保溫效果,使用者還應了解其貯存注意事項:

                                                                                                                                               

                                                                                                                                                  1.泡沫盒內含有易燃、易揮發的發泡劑,儲存時避免起火。

                                                                                                                                               

                                                                                                                                                  2.產品貯存場所應陰涼通風良好,為防止發泡劑散失過快,保持適中倍率,貯存溫度在25℃以下,并經常保持通風。

                                                                                                                                               

                                                                                                                                                  3.蘇州泡沫箱盡量采用先進先用原料,保持新鮮,以獲得穩定的操作條件,產品性能優良。
