What McCain Classic Fries is made of, ingredients and materials
McCain Classic Fries arrive in a paper/cardboard bag with a grease-resistant coating applied to the interior. This coating prevents oil from the fried potatoes from soaking through and damaging the packaging or creating mess. The identity of the grease-resistant agent is not publicly disclosed by McCain; in the frozen food industry, such coatings commonly contain PFAS "forever chemicals" (PFAS), which migrate into food in small amounts and do not break down in the body or environment.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
PFAS
Paper food packaging with grease-resistant finish typically contains PFAS compounds. McCain does not disclose composition, and no independent testing of this specific product is on public record. Migration into fatty foods like fries is known to occur at low levels.
Source, ATSDR ↗Packaging coating degradation and leaching
Extended storage in warm conditions or exposure to acidic or high-fat foods may degrade the grease-resistant coating. If the coating breaks down, micro-particles or residual coating chemicals could theoretically transfer to food, though this is not established as a frequent problem in normal use.
Acrylamide from cooking (product, not packaging)
French fries are a known source of acrylamide, a chemical formed when starchy foods are heated to high temperatures. This is a product composition issue, not a packaging hazard, and is inherent to fried potato products regardless of brand. Cook according to package instructions to minimize formation.
Plastic layer or inner film components
Some McCain bags may include a thin plastic layer or film as part of the internal structure to enhance grease resistance. Composition and migration risk of this layer are not disclosed; heating or damage to the bag could theoretically release plastic particles, though this is not documented as a practical risk.
What’s reassuring
Microbial contamination risk (general frozen food)
No recalls or public health incidents specific to McCain Classic Fries related to bacterial or viral contamination are on record. Frozen foods are generally stable if kept at 0°F or below and handled according to package directions.
How is this PFAS grade calculated?
The brand's record and disclosure
McCain has not issued public statements about the composition of its grease-resistant coatings or committed to PFAS-free alternatives. The company does not appear on lists of food brands that have pledged to eliminate PFAS from food contact packaging. This silence is notable given regulatory pressure in Europe and some US states to phase out PFAS in food packaging by 2025 to 2027.
How it compares in its category
Most frozen french fry brands use similar grease-resistant paper coatings; Ore-Ida, Lamb Weston, and store brands typically employ the same approach. Some frozen fry producers have begun switching to coatings not linked to PFAS, though this shift is not yet universal. McCain's lack of public commitment puts it in the middle-to-lower tier of transparency for this product category.
If you buy it
Store unopened bags in a cool, dry place; exposure to heat or moisture before cooking will not significantly increase PFAS transfer. Do not allow the fries to sit in the opened bag for extended periods after cooking. Transfer leftovers to glass or ceramic containers rather than keeping them in the original packaging. If PFAS exposure is a priority concern for your household, consider requesting McCain's coating disclosure or switching to brands with transparent PFAS-free or reduced-PFAS claims.
