#9 White 5.5x4.5" Grease Resistant Bags (2,000/Case)
Wait for the brand to disclose coating chemistry; grease-resistant food packaging commonly contains PFAS.
The brand's grease-resistant bag coating is not identified in public product specifications. Grease-resistant food-contact papers historically rely on PFAS-based treatments, and the brand makes no PFAS-free claim or third-party certification.

What #9 White 5.5x4.5" Grease (2,000/Case) is made of, ingredients and materials
These are kraft paper bags with an applied grease-resistant coating. The coating formula is not specified by the brand in available product documentation. Grease-resistant food packaging almost universally relies on either fluorochemical (PFAS-based) or silicone coatings; without disclosure, the PFAS content cannot be ruled out. The paper substrate itself is neutral, but the coating is where chemical leaching risk concentrates, especially when in contact with fatty baked goods, oils, or foods stored at elevated temperatures.
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
The brand has not disclosed whether the coating is PFAS-based. Industry standard for grease resistance in kraft bags historically relies on fluorochemicals; without confirmation otherwise, PFAS leaching into fatty foods is a reasonable concern, particularly during storage or if the coating is abraded.
Source, ATSDR ↗Coating breakdown and microparticle migration
Grease-resistant coatings on paper can degrade with age, moisture, or mechanical stress. If the coating flakes or peels, small particles may migrate into packaged foods. No specific degradation data for the brand's formulation is publicly available.
Formaldehyde / VOCs
Some grease-resistant coatings release volatile compounds during manufacture or storage. Residual solvent exposure is typically low for the end user but has not been independently tested for these specific bags.
Source, ATSDR ↗What’s reassuring
Ink or adhesive contaminants from printing
If the bags are printed (e.g., with branding or barcodes), ink-based heavy metals or volatile organics are possible but not documented for this specific product. Standard food-grade inks are regulated, but composition depends on supplier and is rarely disclosed at the SKU level.
Allergen or contamination retention in porous paper
Kraft paper itself can harbor dust, mold spores, or residues from recycled fiber. The grease-resistant coating may reduce permeability but does not eliminate this baseline risk. Proper storage and handling minimize concern.
How is this PFAS grade calculated?
The brand's record and disclosure
The brand is a major paper and packaging manufacturer without a published commitment to exclude PFAS from food packaging. The company has not voluntarily disclosed the chemistry of grease-resistant coatings across its product line. No public statement positions ahead of or behind industry standards on fluorochemical phase-out. This silence is significant, competitors in the foodservice packaging space have begun to disclose or eliminate PFAS in response to regulatory and consumer pressure, making the brand's non-disclosure a notable gap.
How it compares in its category
Standard kraft bakery bags with grease-resistant coating occupy a middle tier of transparency. Some manufacturers (notably compostable and certified-sustainable brands) now offer PFAS-free alternatives using silicone or other non-fluorinated barriers, though these are typically at premium pricing. Bulk commodity suppliers like rarely lead on chemical transparency; their products are generally assumed to use conventional fluorochemical coatings unless stated otherwise. For budget-conscious buyers, these bags perform as expected; for those prioritizing chemical safety, the lack of disclosure is a red flag.
If you buy it
Use these bags for dry or moderately moist baked goods with minimal oil exposure. Avoid extended contact with greasy pastries, fried items, or foods stored warm. Do not microwave or heat foods inside the bags. Replace bags immediately if the coating shows flaking, tears, or breakdown. Store unopened cases in cool, dry conditions; humidity can accelerate coating degradation. Consider these a temporary-use product pending the brand's disclosure of coating chemistry or a switch to a manufacturer with transparent, PFAS-free alternatives.
