Many friends and the production of ultra-low temperature ice bag has a relatively high interest in the principle of ultra-low temperature ice bag production is what?
First of all, we first understand the components of ultra-low temperature ice pack, ultra-low temperature ice bag mainly by a low temperature phase transition temperature of the highly efficient cold storage agent and a corrosion-resistant double-layer nylon composite membrane composition.
Ultra-low temperature ice bag production process is through a fully automatic tanker filling machine according to the quantitative ultra-low temperature phase transition temperature of the efficient cold storage agent poured into the nylon composite membrane material processing from the plastic bag, the last staff through the edge Machine will package the edge, that is completed the production of ultra-low temperature ice bag.
The principle of ultra-low temperature ice bag is through the principle of phase change to achieve the protection of low-temperature items, so as not to let the low temperature items due to the external temperature is destroyed.
