There is nothing wrong with it, but it is soaked in warm water for a while, then it flashes and the taste drops a lot. As for why do you want to repackage? That's because the can itself is formed at high temperature during the production process. When stored, the local temperature is too low (-20 degrees) and the storage time is long. After being taken out of the low temperature, it will become a block after preheating. Eating it will not harm your health, but it is recommended not to eat it, because it will affect your appetite and taste bad (the local dialect is pimping)
