You may find it hard to open fruit or sauce cans for the pressure difference between inner space of the cans and the atmosphere. You have to put your strength to try to unscrew the lid but sometimes still fail. Mostly, cans are made of glass, so you’d better not attempt to lever the lid. So it might be a problem to open cans with bare hands.For
this problem, Easy To Open is a newly redesigned packaging. The lid is surrounding to the can by plastic encapsulation, a part of which is sticky and glued around the top. While opening, just tear apart the no sticky portion and then, the lid will rotate synchronously, so the can is opened easily.
