A coated paperboard is disclosed which includes a barrier coating containing substantially no fluorochemical or wax, exhibiting good resistance to oil and grease, no tendency toward blocking, the coated paperboard being fully repulpable as well as compostable. The coated paperboard may further have a printable coating on a surface opposite from the barrier coating.

The invention concerns a CF paper comprising a base paper and a coating applied thereto, said coating containing at least one binding agent, at least one ink-absorbing agent, at least one coating pigment and conventional additives, and being characterised in that the at least one binding agent comprises a cross-linked biopolymeric material in the form of nanoparticles.

The present invention comprises a method, process, and composition that enhances the performance of paper straws through the use of zein treatments which significantly enhance the wet strength of paper straws. Selection of the paper substrate found that Hanji paper displays remarkable durability, reinforcing performance of the straws even when exposed to water and high salinity. Furthermore, the present invention exhibits substantial effectiveness in curbing starch migration from the paper straws, creating a protective barrier against starch-based glues that might otherwise compromise beverage flavor and pose gluten-related concerns. Additionally, the present invention outlines a method for crafting spirally-wound straws using a biodegradable paper strip impregnated with the zein treatment. The straws of the present invention offer an adhesive-free, sustainable, and environmentally-friendly solution for making durable straws.
