Cortec is pleased to announce that its S-8 corrosion inhibitor additive for food-can processing has been awarded the USDA Certified Biobased Product label! S-8 can now display a unique USDA label that highlights its percentage of biobased content and signifies its qualification to meet mandatory federal purchasing requirements under the USDA BioPreferred program.

“We applaud Cortec for earning the USDA Certified Biobased Product label,” said Vernell Thompson, USDA BioPreferred program. “Products from Cortec are contributing to an ever-expanding marketplace that adds value to renewable agriculture commodities, creates jobs in rural communities, and decreases our reliance on petroleum.”

Cortec is proud of this “green” chemistry achievement and addition to its growing line of USDA certified biobased products, which represent a long-standing commitment to environmental responsibility.

S-8 contains 71% USDA certified biobased content and is formulated with FDA compliant ingredients. It is designed for corrosion protection of sealed food cans during washing and sterilization. While most of a can’s life may be spent sitting on a shelf in a dry environment, newly packed and sealed cans pass through hot steam for sterilization, sometimes followed by a cold-water bath, before ever reaching the warehouse, store, or pantry shelf. Exposure of the metal can lead to steam, water, and air at this stage of processing is a perfect recipe for corrosion, which could lead to serious repercussions for the producer, seller, and consumer if not properly addressed. S-8 can be added at a very low dose to the sterilization and cooling water to safeguard against the risk of flash corrosion from rinsing and sterilization.

Three phases of inhibitor action—in the water, in the air, and at the air-water interface—give S-8 unique protective abilities for the steam sterilization environment, inhibiting corrosion even when the cans are not fully submerged in S-8 treated water. The additive leaves behind a persistent thin protective layer that will not cause sticky deposits on the surface of the can. Benchtop laboratory tests show outstanding film persistency and stability in a wide temperature range. This “green” filming corrosion inhibitor contains salts of fatty amino acids and amino alcohols as the active ingredients and does not hydrolyze during application.

A large food can producer in Croatia started using S-8 in 2012 in conjunction with S-14 for corrosion protection and scale control in process water used to wash and sterilize cans. The water treatment additives solved the scale and corrosion problems, and, as of five years later, it was reported that these two products were still being used with satisfaction.

Cortec is proud to contribute to the marketplace with a “green” chemistry product that is both useful and sustainable. First, the product meets an important need to protect food cans from flash rust at the end of the canning process. Second, the product uses FDA compliant materials to make it suitable for use on packed and sealed food cans. Third, the product relies on renewable, biobased raw materials to reduce the consumption of non-renewable resources. Furthermore, S-8 can be used by US federal agencies and their contractors who need to meet minimum biobased content levels when purchasing corrosion inhibitors.

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.
