Italy developed a PTFE wine stopper

Recently, Tejnoji Mika of Italy developed a Teflon wine bottle stopper, which has more advantages than the commonly used wine bottle stopper. This Teflon wine cork is covered with a layer of fine powder of polytetrafluoroethylene polymer produced by DuPont in the surface of an ordinary wine stopper. The smooth, non-chemical polymer stoppers are easy to plug, easy to pull out, and better prevent the release of alcohol in the bottle. Therefore, it does not affect the taste and mellowness of the wine. The PTFE membrane layer outside the stopper can also resist the erosion of any solution.
