The shelf life of soft drinks in polyethylene terephthalate (PET) bottles is greatly limited by the barrier properties of PET, in particular when it is under pressure, such as from carbonation. If the packaging leaks CO2 or if oxygen from outside can penetrate it, that will change the flavor and quality of the soft drink.

Longer shelf life due to PlasmaPlus® barrier-coating

Plasmatreat has developed a nano-coating for the soft drink industry that is transparent like glass and yet flexible and shock and friction resistant. This nano-coating significantly reduces diffusion and extends the shelf life of the soft drink. The coating is applied using the innovative and cost-effective PlasmaPlus® process and can be applied on both the inside and outside of the packaging.

This same improved barrier property provides a solution for the pharmaceuticals industry as well when this nano-coating is applied to plastic packaging to extend the shelf life of medicines and ensure their long-term active ingredient properties.
