In these difficult days, perhaps now more than ever, society is about to realize the importance of conserving resources—both for economic and environmental purposes. In the paper packaging sector, this translates into the use of materials that can be repulped and made into other paper products, rather than going directly to the landfill after their first use. For the many users of moisture barrier packaging, this presents a special challenge, as polyethylene and wax coatings have historically been used to seal porous paper to create a moisture barrier. When coated this way, the resulting paper product is an environmental problem and cannot be recycled through normal channels.

Due to its strong emphasis on developing non-hazardous, environmentally friendly options for packaging and/or corrosion protection, Cortec® Corporation has been able to successfully present the market with a viable, competitive alternative to traditional moisture barrier packaging. Cortec’s EcoShield® Recyclable Barrier Paper and Linerboard are coated with a water-based barrier coating that resists moisture, grease, and oil. When tested according to ASTM E-96, EcoShield® Recyclable Barrier Paper shows a Water Vapor Transmission Rate (WVTR) comparable to polycoated paper and far superior to waxed paper:

EcoShield® Recyclable Barrier Paper and Linerboard are fully recyclable/repulpable into other types of paper products such as boxes, cardboard, and other corrugated materials. This represents good resource stewardship while still achieving critical packaging qualities. Users of EcoShield® Recyclable Barrier Paper and Linerboard thus have the opportunity to contribute to a “circular economy” while still getting the benefits of moisture barrier packaging.

EcoShield® Recyclable Barrier Paper and Linerboard can be used in a variety of applications, such as packaging oily and greasy parts/items or protecting other moisture sensitive components. To broaden its potential uses, EcoShield® Recyclable Barrier Paper and Linerboard are made from components formulated in compliance with FDA Code of Federal Regulations Title 21:

• §176.170-Components of paper and paperboard in contact with aqueous

and fatty foods

• §176.180-Components of paper and paperboard in contact with dry food

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.
