Production process and packaging material for cold pack […]
Production process and packaging material for cold packs, often do not use or use ice bag ice box ctesms friends, often in the ice ice storage box has some problems or questions on the use of refrigerant charging. When we use the ice pack ice box, we first freeze the ice pack ice box in the fridge or freezer for about 10-12 hours. After the ice pack is completely frozen into solid, it can be removed and used.
Fully frozen to solid indicates that it has been sufficiently cooled. If we put the ice pack that has been completely frozen into solid state to keep cool, it will not continue to absorb cold energy, because it has enough cooling and enough cooling capacity. In summer, the temperature gradually increased, need to use more and more ice cold preservation products, ice ice box purchase large quantities of products required temperature range has become an important work of the purchasing department in many enterprises, so many of my friends and the principle of ultra low temperature ice has relatively high interest.
Production process and packaging material cold packs, consisting of high coolant and a double nylon composite film corrosion resistance to freezing and ultra low temperature ice mainly by an ultra low temperature phase transition temperature. The production process of ultra low temperature ice is through a cold storage automatic filling machine according to quantitative ultra low temperature phase transition temperature, coolant is poured into the nylon composite membrane material into a plastic bag, at the end of the staff through edge of the packing bag is made of super low temperature sealing, ice bag.
