Experts who want to delve deeper into the chemistry of pharmaceutical glass can now obtain a 4:30 minute visual introduction from Schott. The company has come up with a video in English on the important role that glass plays in the pharmaceutical industry. ‘What is glass’ tells how this fascinating material starts out its life as sand and how it is transformed into the high-quality type-I-glass used in syringes or vials, for example. Schott’s new video can be viewed at

The scientific basis was provided by Bettine Boltres, product manager, pharmaceutical tubing at Schott, “Glass in its purest form – known as quartz – is a very stable material but comes with limitations in terms of processability,” Boltres explained. “In order to make it processable, however, adding certain substances to the glass formulation – making it a borosilicate glass – is a necessary step. The challenge for pharmaceutical glass types is to offer excellent hot forming capabilities without compromising the chemical stability. How this is realized, is explained in the video.”

Schott’s extensive knowledge is not without reason – the international technology group has been active in the field pharmaceutical glass for over a century. It only seems natural to end the film by quoting the company’s founder Otto Schott, who once said that glass was not just a pure coincidence. “Looking at the increasing need for high-quality materials, it seems that his words are more relevant today than ever before,” Boltres concluded.

Packaging South Asia is the cooperating media partner for drupa 2016 which is scheduled to be held from 31 May to 10 June at Dusseldorf, Germany.

The Covid-19 pandemic led to the country-wide lockdown on 25 March 2020. It will be two years tomorrow as I write this. What have we learned in this time? Maybe the meaning of resilience since small companies like us have had to rely on our resources and the forbearance of our employees as we have struggled to produce our trade platforms.

The print and packaging industries have been fortunate, although the commercial printing industry is still to recover. We have learned more about the digital transformation that affects commercial printing and packaging. Ultimately digital will help print grow in a country where we are still far behind in our paper and print consumption and where digital is a leapfrog technology that will only increase the demand for print in the foreseeable future.

Web analytics show that we now have readership in North America and Europe amongst the 90 countries where our five platforms reach. Our traffic which more than doubled in 2020, has at times gone up by another 50% in 2021. And advertising which had fallen to pieces in 2020 and 2021, has started its return since January 2022.

As the economy approaches real growth with unevenness and shortages a given, we are looking forward to the PrintPack India exhibition in Greater Noida. We are again appointed to produce the Show Daily on all five days of the show from 26 to 30 May 2022.

It is the right time to support our high-impact reporting and authoritative and technical information with some of the best correspondents in the industry. Readers can power Packaging South Asia’s balanced industry journalism and help sustain us by subscribing.
