What is the principle of ultra-low temperature ice bag production? Shanghai ice bag
Summer is coming soon, the temperature gradually increased, the need to use ice bags cryopreservation of the products are more and more, a large number of procurement products required temperature range of ice pack ice box as most of the important business procurement departments, so many friends and ultra- Ice bag production principle has a relatively high interest, that ultra-low temperature ice bag production principle 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 high-performance 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 cold storage filling machine according to the quantitative north and south Sichuan R & D ultra-low temperature phase transition temperature of the efficient cold storage into the nylon composite membrane material from the processing of plastic bags, and finally There are staff of the North and South River through the edge banding machine will package the edge, that is, the completion of ultra-low temperature ice bag production.
Ultra-low temperature ice bag principle is through the phase change of the working principle to achieve the protection of low temperature items, so as not to let the low temperature items due to the external temperature is destroyed.
