Toyo-Morton, Japan’s leading manufacturer of laminating adhesives and a member of the Toyo Ink Group, has developed the Ecoad EA-B3860/EA-B1290, a high-solids solvent-based adhesive for use in the dry lamination of multilayered films in flexible packaging structures. Containing over 40% coating solids by weight, the new formulations contain less solvent and thus bring down overall CO2 emissions during lamination by roughly 25% when compared to the company’s general-purpose laminating adhesives. 

The high-solids design also reduces waste recovery and disposal for greater operational efficiencies and a cleaner work environment. The new Ecoad systems were formulated with bio-based or renewable content of 10% by weight at the dried adhesive layer, making them a more eco-friendly alternative in packaging materials.

Toyo-Morton products reduce CO2 emissions during coating

In recent years, packaging converters in the food, pharma, cosmetics and other consumer and industrial markets are readily adopting sustainable materials as they seek to stay in step with the continuous push for greener end-products by industry, regulatory bodies and consumers alike.

To address this growing trend, Toyo-Morton engineers in Japan successfully raised the solids content of its laminating adhesive compositions to 40% in the coating process while converting a portion of raw materials with those derived from natural sources. Typically, increasing the solids content causes the viscosity of the coating adhesive to increase, which can impair coating performance and degrade various physical properties. However, by applying its proprietary polymer design technology, Toyo-Morton could eliminate these tradeoffs and achieve high solids and bio-based content without compromising performance.

The Toyo Ink Group is a pioneer in developing bio-based inks, coatings and adhesives, in particular for the packaging sector. As such, we are well aware of the regulatory and social demands that converters face to provide more sustainable and environmentally friendly packaging,” said Satoshi Maeda, general manager of Toyo-Morton’s technical department. “With the new Ecoad laminating adhesive systems, we were able to respond to our customers’ requirements for reduced use of hazardous chemicals at the raw materials sourcing stage and improved processing efficiency while actively applying renewable raw materials to the extent possible. At Toyo-Morton, we are committed to developing products that reduce customers’ environmental footprint and to lowering CO2 emissions of our products throughout their entire life cycle in accordance with ongoing life cycle assessment analysis.”

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.
