The cold pack has a high cold capacity, and the release of the cold source is uniform and slow (the release rate is 6 times slower than that of ice cubes), and it has the characteristics of good cold retention time;
No water pollution. Since ice cubes will cause water stains when they are released, it is easy to cause moisture to affect the quality of the goods, so cold storage bags are widely used in air cargo;
Can be reused, saving cost;
Polymers are non-toxic, tasteless (but inedible) environmentally friendly products. It is formulated with high-tech biological materials and has a certain degree of elasticity. It still maintains flexibility at a temperature of -190℃.
Can be reused N times, both cold and hot, the lowest can be frozen to -190℃, the highest can be heated to 200℃, and can be cut to any size
