Use our Aquaseal water based barrier coatings for film based flexible packaging.
Aquaseal™ 2218 is a water based solution of a fully hydrolysed PVOH. Used for paper/re-moistenable adhesives, as raw material for sizes and textile finishes, as binder resin in surface finishing of paper, for regulating processing characteristics of water based coatings. Gas barrier.
Aquaseal™ X 2281 is a novel high solids barrier coating based on a vinyl alcohol resin in water. Despite its high degree of hydrolysis, it has been possible to achieve a 20% solid content whilst maintaining the viscosity at 500mPas allowing higher coating weights to be achieved with existing equipment. Designed as a product for coatings on paper or film, for example as a printable oxygen barrier. The barrier performance remains humidity sensitive above about 23°C/65% humidity but this can be improved with cross-linking.
