Traditional ice packs require huge costs.

Nowadays, with the improvement of logistics efficiency and the vigorous development of online shopping, there are more and more categories that can be purchased online. In recent years, fresh online shopping has become more and more popular. In the past, it was difficult to buy fresh vegetables, fruits, fresh food and other foods online, because long-distance logistics was slow and time-consuming, and it was difficult to ensure the freshness of food. Nowadays, online shopping for fresh food is not only fast in delivery, but also equipped with special fresh-keeping products, usually ice packs. With the widespread use of ice packs, recycling has become a problem.

This kind of ice pack can keep food fresh for a period of time without decay, which is of great significance to fresh online shopping. This kind of ice bag is not a simple fresh-keeping piece with ice, but a fresh-keeping product composed of some chemicals, and its temperature is as low as ice, which plays a fresh-keeping role. At present, this kind of ice pack is used more and more, but there is no large-scale recycling method in the market. It is usually sent to the consumer's home and handled by the consumer himself.

Although it is not difficult to make ice packs with the current technology, it contains a lot of chemicals, which will pollute the environment if discarded at will, and the ice packs will last for a long time. If it is only used for one-time logistics distribution, it is also a waste of resources. Some consumers with strong environmental awareness will not throw away the ice packs immediately after receiving the goods, but will reuse them for other things that need to be kept fresh in their lives, which is very good for the recycling of ice packs and saving resources.

However, the recycling and economical use of ice packs cannot rely entirely on consumers' personal consciousness, so it is difficult to reuse them on a large scale. The best way is to hope that the relevant departments can establish some special places to recycle ice packs, recycle them uniformly and treat them centrally. In addition, for logistics companies and fresh food merchants, these ice packs can also be recycled after each delivery to customers for the next logistics distribution, so as to realize repeated recycling of ice packs.
