Greaseproof paperboard is specialty packaging board engineered with an impervious surface barrier that prevents oils, fats, and moisture from penetrating into the paper fibers.
### Types of Greaseproof Barriers:
1. Aqueous (Water-Based) Dispersion Coatings (Eco Standard): Applied as a thin liquid barrier that cures on the board. 100% recyclable and repulpable in standard paper recycling mills.
2. Vegetable Parchment / Mechanical Density: Paper fibers refined to eliminate microscopic pores, creating a natural mechanical barrier without synthetic chemicals.
3. Biopolymer Coatings (PLA / PHA): Plant-derived bio-coatings that provide waterproof and oilproof barriers while being industrially compostable.
4. Avoid PFAS (Forever Chemicals): Modern packaging standards strictly prohibit fluorinated chemicals (PFAS/PFOS) in food packaging due to health and environmental regulations.
### Common Uses:
- Fast-food burger and fry boxes
- Donut and pastry bakery packaging
- Pizza boxes and takeaway meal cartons
- Smoked meats, cheeses, and deli product packaging.
