SiO2’s patented barrier technology combines the benefits of glass and plastic, without any of their drawbacks. This glass-like coating, which is applied to our polymer containers, provides a highly effective barrier to environmental gases, moisture, and particles. There are no metal ions, no particles, no leachables, and no oils. Our technology creates a completely inert container. The advantages of SiO2’s primary containers are: Thermal Stability & Integrity, Inert, Chemical Stability, Gas Barrier, Mechanical Durability, No Breakage, and Precision Molding.
