Bag-in-Can Technology

Eye Drops and Sterility

Although an eye drop package is sealed and manufactured to FDA pharmaceutical standards, sterility cannot be guaranteed once the package is opened. When applying eyedrops, the dropper often touches a part of your eye or face where it can pick up bacteria and viruses. If somebody else later uses the dropper, there’s no telling what they could be putting into their eyes. When using eyedrops to clear your eyes in an emergency with smoke, perspiration and filthy hands, the situation can be even riskier.

Nature’s Tears EyeMist is the first pharmaceutical product to employ Bag-in-Can Technology to keep the contents of its aluminum canisters safe – from the first application to the last.

How it works.

With Nature’s Tears EyeMist, the assembly process begins with a plastic, aluminized barrier bag which is attached to a plastic applicator nozzle. The rigid aluminum canister, with bag and nozzle in place, is then pressurized with nitrogen, an inert chemical that comprises 80% of the air we breathe. Nitrogen has a greater capacity to pressurize than oxygen or air, retards freezing, and microbes cannot live in nitrogen. The unit is then sealed with a rubber gasket. In the extremely unlikely event that the gasket fails, the unit would depressurize and simply not work. As long as the seal is intact, the contents remain clean and sterile.
