Can heat shrinkable sheets be heated repeatedly for how long?

Yes. Heat shrinkable sheet is a kind of memory plastic. After radiation processing, the linear structure of the molecules is changed into a network structure, so it has a "memory" function and can return to its original shape when heated again. Heat shrinkable sheet is also called shape memory plastic. There are many other materials in life that have "memory" functions, such as rubber pillows, memory alloy glasses, and heat shrink tubing.
