PROSEAL+: SGD Pharma’s pre-treated glass for thermosealing applications

Ready to seal glass bottles for an optimal hermetic seal 


Many of today’s oral pharmaceutical products are sensitive to moisture and oxygen. That is why selecting the right primary packaging materials and closure systems are critical for maintaining shelf-life.

For oral products, especially sensitive ones such as powders and solids, adding a moisture and oxygen resistant hermetic seal to the glass bottle brings huge benefits. A hermetic seal protects both the contents and consequently the user as the seal also provides an added level of security as a tamper evident feature.

For over 15 years, SGD Pharma has offered an industry leading solution to bottle sealing challenges. Using a well-established external treatment on the sealing surface of the glass greatly enhances and guarantees an optimal seal adhesion of the foil. Our PROSEAL+ glass bottles are suitable for both induction or conduction processes, both of which help forming a completely hermetic seal which can maximize product shelf life and provide best-in-class product protection.

Our external treatment is suitable for use in pharmaceutical-grade packaging and is food contact compliant.
