1. Ice Box shell for food-grade HDPE material, clean and beautiful. The size of outer box can be customized according to customer's needs. 2. The content is high polymer, safe, non-toxic and tasteless. It has passed the non-toxic test of the testing center of Shanghai Chemical Institute. 3. The Ice Box adopts the scientific design principle, the ice box mouth uses the double-layer Seal, through the leakage experiment 2 meters high free, falls, undergoes 80kgs negative pressure to have no leakage. When the ice box is frozen into a solid, effective to prevent expansion, to ensure that the expansion rate of 15% within 4.5% . Cold: Ice Box composition through the addition of scientific formula, increase the heat capacity of water, increase the ice box cold storage effect, can be insulated box, cold storage temperature to maintain a longer time 5. Slow cooling: by changing the physical properties of the medium in the ice box, the cooling time of the ice box is increased, and the time of the cold storage temperature is prolonged 6. The outer packing is strong and durable: the outer packing PE material (HDPE) increases the compression strength and abrasion resistance of the ice box packing, reduces the cold brittleness coefficient, and is more suitable for the actual application needs of enterprises. Seven. Safe and non-toxic; through the detection, non-toxic tasteless, will not burn explosion, non-corrosive
