AI Technical Summary
Glass containers used in pharmaceutical packaging face challenges such as breakage during processing, contamination, and the need for complex multilayer coatings that complicate production and increase costs, while also requiring resistance to high temperatures and mechanical stress.
A glass container with a surface region containing nitrogen (N) in the range of 0.3 to 10 at-% and silicon (Si) at least 5 at-%, determined by X-ray photoelectron spectroscopy, where chemically bound N is present throughout a functionalizing depth of 5 nm to 10 µm, enhancing durability and reducing contamination risks without the need for coatings.
The solution increases the durability of glass containers, reducing breakage and contamination, while maintaining transparency and optical inspection capabilities, and simplifies the production process by eliminating the need for complex coatings, thus enhancing production efficiency and safety.
