Toyochem achieves new adhesive with up to 80% biomass content

Biomass content increased by synthesizing polymers from bio-based raw materials.

Toyochem, a member company of the Toyo Ink Group, has developed a new pressure-sensitive adhesive (PSA) with a high bio-based content for use in packaging, labels, and tapes. According to Toyochem, the bio-based content for the company’s Cyabine series of polyurethane adhesives recorded values up to 80%, while the Oribain series for acrylic adhesives up to 75%.

Both series also include a removable PSA composition with 10% bio-based content, a feature that had had considered “difficult” accomplish by using conventional bio-based adhesives.

As countries worldwide work to transition to a circular economy, materials produced from biomass are expected to play a key role. Given the focus on mitigating climate change and its impact, research and investment have shifted from petroleum-based economy to sustainability based on recycling and renewable resources. As such, bio-based materials have attracted attention across a diverse range of fields, due to the ecological advantages that come with their use.

Toyochem achieved the new PSA by synthesizing the polymer from raw materials derived from biomass. As a result, the new adhesive gives packaging converters who are looking to incorporate biomass into their packaging structures an eco-friendly alternative without compromising on performance.

The new Cyabine and Oribain adhesives are currently available in Japan with a worldwide release to follow in the coming years.
