Glymo-free Flextra adhesives

21.11.2019 H.B. Fuller Europe GmbH (Zurich, Switzerland) has launched a series of products free of epoxy silane commonly known as e.g. Glymo, within its Flextra range of adhesives for flexible packaging. The renowned adhesive provider also confirmed that this range does not contain organotin or BPA and specific grades are free of cyclic esters.

This modification gives converters and food manufacturers complete confidence that when they use one of H.B. Fuller's Flextra adhesives for their flexible packaging, they are choosing a compliant and food safe adhesive solution that will give them the performance they're looking for.

Growing regulation

This reassurance is key at a time when converters and food manufacturers face growing regulation and increased pressure from consumers.

The Flextra range includes both solvent-based and solvent-free products for medium and high performance applications. Individual solutions also offer additional benefits such as room temperature curing, fast curing and PAA decay, as well as the option to use an aliphatic system to avoid PAA altogether.

Replacing Glymo

The announcement from H.B. Fuller is in line with recommendations from FEICA, the Association of the European Adhesive & Sealant Industry, for members to replace Glymo in food packaging adhesives before mid-2020. This follows guidance from the European Food Safety Authority (EFSA) that Glymo, which is typically used to improve adhesion to inorganic surfaces such as aluminium or SiOx coated films, has a genotoxic potential. It is expected that the regulatory classification will change from 10ppb to 0.15ppb shortly.
