What is the problem of today's plastic zip-bag for food? We have been use the zip-bag as a food container. It's hard to know when the food stored. Even the one, who stored the food can easily forget.Today's zip-bag users need to post or write a memo on the zip-bag but, most of user get lazy to do it. To solve this problem we suggest a new marking method of recording the date without taking extra steps or using tools.
