The standard tech ice side is a dense plastic side and a non-woven one side
Is mainly used for perishable products, biological agents, and all products need to be refrigerated transport (if ice away with products of science and technology, when the transport can't back to reuse, suggest using standard 2) standard of science and technology of ice while design is the disposable use, but after careful use cases, also can be used many times (note: but can't type and HDR four layers of science and technology, compared to ice HDR model of the four layers, repeated use, hot and cold dual use)
Usage: put ice in water science and technology, rubs with the hand, make ice expansion of science and technology, expanding to 1 centimeter or so for the best, take out expansion after the dry on the surface of the water, and then in the refrigerator frozen can use.
