We always use plastic wrap to keep the food fresh. However we sometimes forget what time the food is covered by the plastic wrap thereby missing the best edible period and causing the waste of food,“Fresh time” a gadget we designed to pack the plastic wrap, can print the specific date on the plastic wrap with the aim of reminder. It helps people to eat food at the best edible period, it also contributes to the physical health of people. With it we no longer worry about whether the food is expired
