As part of our recent developments for several customers we are looking to replace conventional layers to coat directly on papers (i.e., "primers") with renewable materials.
In formulating a comprehensive solution for sustainable and potentially food-safe packaging, the call for proposal incorporates requirements for primers within the broader context of water-based dispersion coating development. Aside from the crucial demand for superior adhesion to paper and compatibility with various coating techniques, a heightened emphasis is also in ultra-high OTR barrier and heat resistance.
We are looking for a water-based dispersion coating solution that strongly adheres to paper substrates and achieves ultra-high oxygen barrier. The coating solution should demonstrate heat resistance (for subsequent extrusion applications).
- Viscosity: 25s-40s according to to DIN 53211, Ø 4 mm, 20°C or viscosity lower than 600 cP
- Thermal stability of at least 300˚C
- Components do not interfere with paper recycling (e.g. wax)
- OTR <1 cc/sqm/24hrs in standard conditions
-
For our eventual solution, we seek the following performance after applying 3 gsm dried coated layer on paper: OTR<=1 at 23˚C, 50%RH and WVTR<=1 at 23˚C, 85%RH
-
Ideally biobased and/or biodegradable
-
Approved food contact
-
Good adhesion on paper and clay coated paper (adhesion strength higher than 5N/15mm)
-
TRL 6+ would be ideal (but solutions that do not meet this maturity are still welcomed)
-
PVDC, PFAS (Polyvinylidene chloride, per- and polyfluorinated substances)
-
Siliconising agents
-
Components that are not suitable for (or interfere with) paper recycling according to CEPI guideline (e.g., components creating microstickiness and visual impurities in paper recycling)
-
Wax dispersion (incl. microcrystalline waxes)
