Kraft Paper Bakery Sandwich / Cookie Bag 8 1/2 " x 1" x 6 1/2" Grease Resistant Bags. for Sandwiches, Pastry Food Snack Wraps Baggies Sleeves 1000 pc.
Wait for Westrock to disclose the grease-resistant treatment as PFAS risk remains uncertain.
This grease-resistant kraft bag lacks any public disclosure about its coating chemistry. Grease-resistant food packaging frequently uses PFAS-based water-repellent coating treatments, though some brands have switched to PFAS-free alternatives.

Material
Kraft paper with grease-resistant coating (type unspecified)
Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
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.
Grease-resistant coating migration (unknown chemistry)
Westrock has not disclosed whether the coating contains fluorinated compounds (PFAS) or alternative treatments. Migration to fatty foods is theoretically possible with prolonged contact or heat; actual risk depends on unconfirmed coating type and food type.
Thermal degradation of coating
If the grease-resistant treatment is polymer or fluorinated, heating (microwave, oven contact) may cause degradation and release of monomers or volatile byproducts. Kraft paper itself is stable; the coating behavior is unknown without chemical disclosure.
What’s reassuring
Ink or printing residues (if printed bags)
Kraft paper bags may carry food-safe inks, but no specific testing or recalls for this Westrock SKU are documented. Standard food packaging regulations govern ink; no hazard is established unless bags are printed on interior contact surfaces.
Recycled fiber contaminants (if recycled content)
Recycled kraft paper can theoretically contain trace metals or foreign matter from prior use, but FDA-approved recycled food contact paper is regulated to exclude hazardous contaminants. No incidents are on record for Westrock bags.
The full breakdown
What it's made of and why it matters
This product is kraft paper, a mechanically processed virgin or recycled cellulose material, with an applied grease-resistant coating. The coating's chemical identity is the critical unknown: it may be a fluorinated compound (raising PFAS concern), a silicone-based treatment, or a wax-polymer blend. Without disclosure, migration risk to fatty foods cannot be assessed. Kraft paper itself is inert and does not leach hazards; the coating is the sole chemical concern.
The brand's record and disclosure
Westrock is a major U.S. paper packaging manufacturer with no public PFAS disclosure policy or certification for grease-resistant food contact bags. No recalls or regulatory violations specific to this product line are on record. The company has not voluntarily committed to PFAS-free coatings in food packaging. Westrock's silence on treatment chemistry is consistent with industry-wide lack of transparency on grease-resistant additives.
How it compares in its category
Most commercial kraft sandwich and bakery bags use grease-resistant coatings; few manufacturers disclose the chemistry. Competitors like Bagcraft and BioMass similarly lack public PFAS commitments. PFAS-free alternatives (silicone-coated or wax-lined kraft) exist but are less common and typically cost more. This product sits in the mainstream opaque segment where grease resistance usually implies fluorinated treatment until proven otherwise.
If you buy it
Use for dry and low-fat foods (crackers, pastries, light sandwiches) to minimize contact between coating and oily contents. Avoid prolonged storage of greasy items; the coating's migration risk increases with heat and contact time. Do not microwave or expose to direct heat, as unknown coatings may degrade. If PFAS exposure is a concern for your household, request Westrock's technical data sheet or switch to verified PFAS-free brands.
