Poor

Skip or contact McCain for coating transparency; grease-resistant food packaging commonly uses PFAS.

Verdict · SkipPFAS coating poses documented concern; no other hazards on record for McCain fries, but grease-resistant paperboard requires manufacturer transparency.

Paperboard packaging with grease-resistant coating typical of food containers. McCain does not publicly disclose whether this coating contains PFAS or Teflon-family coating.

What Mccain Flavorlast Thick Potato Fry is made of, ingredients and materials

McCain Flavorlast Thick Potato Fry bags are paperboard lined with a grease-resistant coating to prevent oil migration and sogginess during freezing and storage. The coating chemistry is not disclosed on packaging or in public McCain documentation. Grease-resistant food-contact coatings commonly rely on PFAS "forever chemicals" (PFAS) to repel fats; these compounds persist in the environment and accumulate in human tissue.

PFAS

Paperboard grease-resistant coatings for frozen food bags frequently contain PFAS. McCain has not disclosed the specific chemistry, and the brand's poor PFAS transparency score (25/100) reflects industry-standard silence on this material.

Microplastics

No recall or published safety data on Flavorlast bags shedding plastic particles or coating fragments. Frozen storage at recommended temperatures minimizes degradation risk.

Heavy metals

McCain packaging is regulated as food-contact material in most jurisdictions; no specific contamination reports are on record for this product. Printing inks on outer surfaces do not typically migrate to frozen product.

Mold or bacterial growth in bag seal

McCain Flavorlast bags are factory-sealed and intended for freezer storage, which prevents microbial growth. Risk is limited if bags remain frozen and unopened until use.

Formaldehyde / VOCs

No published data indicates formaldehyde emissions or off-gassing from McCain frozen fry bags. Paperboard food packaging is generally lower-emission than foam or laminated plastics.

How is this PFAS grade calculated?

The brand's record and disclosure

McCain has not published a public statement identifying the specific grease-resistant coating chemistry used in Flavorlast packaging. No third-party certifications (such as PFAS-free labeling or sustainable packaging claims) are visible on product marketing. The brand's silence on coating composition is consistent with broader industry opacity; few frozen-food manufacturers voluntarily disclose PFAS in food-contact materials.

How it compares in its category

Most frozen french fry bags use grease-resistant paperboard, and McCain is a major player with no public PFAS reduction commitment. Competitors (Ore-Ida, Lamb Weston private label) similarly do not disclose coating type. Products marketed as PFAS-free or sustainable are rare in this category, making Flavorlast typical rather than distinctive in either direction.

If you buy it

Store unopened bags in a cool, dry place; freezer storage is appropriate per label directions. Do not microwave the bag itself; transfer fries to a microwave-safe dish or oven tray. Bag contact with fries is brief and occurs at frozen or moderately heated temperatures, reducing leaching risk compared to hot-fill or extended storage scenarios. If concerned about PFAS exposure, contact McCain customer service to request documentation of coating composition.
