I tore off the warm packing bag, but the paper hasn't been torn off yet. What should I do? I thought it would take a long time.
You lost the outer layer of the package. You put it in another pocket that can be put in, and then put it in a book to squeeze out the air inside. The contents were originally one piece. If it becomes soft and small particles in a few days, it can't be used. If it is still large, it can still be put.
