Avant Cheeseburger Wrappers
Skip until Burger King reveals packaging coating composition.
Burger King wrapper coatings resist grease, a classic PFAS application in food packaging. Burger King discloses nothing about composition.

What’s concerning
Waterproof / stain-resistant treatment
Water-repellent treatments have historically contained PFAS chemicals.
Category baseline
PFAS exposure happens more often with clothing products.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
PFAS
Burger King's refusal to disclose coating composition and historical industry reliance on PFAS in burger wrappers makes fluorinated compounds likely present, though not confirmed. PFAS can migrate into fatty foods like cheese and meat.
Source: ATSDR ↗Non-fluorinated coating leachates (if silicone or proprietary alternative)
If the coating is silicone or a proprietary non-PFAS alternative, migration of oligomers or additives into food is possible under warm or fatty conditions. No specific studies on Avant wrapper composition are publicly available.
Ink or adhesive contamination from printing
Burger King branding and graphics on the wrapper may use inks or adhesives; if these contact the interior food surface, heavy metals or solvents could leach, though food-grade standards typically limit this risk.
Thermal degradation of coating during hot-food contact
Grease-resistant coatings can degrade when exposed to hot, fatty foods, releasing breakdown products into the meal. The temperature profile of a fresh cheeseburger in contact with the wrapper creates conditions for potential leaching.
Microplastic or coating particle shedding
If the coating is synthetic or poorly adhered to the paper substrate, mechanical wear from handling or food friction could release microscopic particles into the food, though visible contamination would be noticeable.
The full breakdown
What it's made of and why it matters
Avant Cheeseburger Wrappers are paper-based food contact packaging with a grease-resistant coating, typical of fast-food burger wrapping. The coating's composition is not publicly disclosed by Burger King, which is the primary concern: grease-resistant coatings on food packaging historically relied on fluorinated compounds (PFAS) or, less commonly, silicones or wax blends. Without transparency from the brand, the specific chemistry cannot be verified as safer. Paper itself is generally low-hazard, but the coating determines food safety risk.
The brand's record and disclosure
Burger King has not publicly disclosed the coating chemistry of its food packaging or committed to PFAS-free alternatives across its supply chain. The company has not achieved certifications like Cradle to Cradle or sustainable packaging standards that would signal independent verification of coating safety. As of available public records, Burger King has not responded to industry pressure regarding fluorinated packaging coatings, placing it behind competitors who have made explicit commitments to phase out PFAS in food contact materials.
How it compares in its category
Most major quick-service restaurant chains (McDonald's, Wendy's) have begun phasing PFAS out of food packaging or publicly committed to safer coatings; Burger King's silence suggests continued use of conventional fluorinated or undisclosed coatings. Paper-based burger wrappers without grease-resistant coating (uncoated kraft) or those using plant-based wax alternatives exist as lower-risk options but are less common in fast-casual settings. Burger King's lack of transparency is a competitive weakness relative to chains pursuing documented safer-coating transitions.
If you buy it
If you cannot avoid this product, minimize exposure by removing food from the wrapper as soon as possible and not allowing it to contact the paper during transport or eating. Do not heat or microwave food in the original wrapper, as this can increase leaching of coating compounds into food. Avoid letting greasy or acidic foods (cheese, sauces) sit in contact with the wrapper for extended periods. The safest approach is to request paper-wrapped items without grease-resistant coating or switch to chains offering documented PFAS-free packaging.
