A Premium Material – Modern Glass Packaging
When glass is made it is heated to around 1600 degrees Celsius, thus killing off any bacteria. Also, organic chemicals that might be present in the recycled glass are burned. This is why glass is used to pack products of premium quality – because no contamination from the packaging occurs. Glass is elegant, and glass packaged products stand out. With many unique shapes, glass containers give your product identity and character. And glass is fully recyclable: a glass bottle can be remade into a new, clean glass bottle. This is why glass is a truly environmentally friendly material – now and in future.
