4 1/4" x 6 1/2" White Bakery Bag w/ Clear Front
Wait for Westrock to disclose coating chemistry or provide PFAS-free certification.
This bakery bag's clear front and grease-resistant properties suggest a water- and oil-repellent coating that historically often contained PFAS. Westrock makes no public disclosure of the coating's chemistry or PFAS status.

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
Westrock has not disclosed whether the coating uses fluorinated PFAS, non-fluorinated alternatives, or silicone-based systems. Older formulations may contain legacy PFAS; newer ones are often safer, but verification is absent.
Source: ATSDR ↗Bacterial growth in damp storage
Paper bags absorb moisture and can harbor mold or bacterial growth if stored in humid conditions or if used to hold moist baked goods. Not a manufacturing defect but a use-case issue requiring dry storage.
What’s reassuring
Plastic window leaching
The clear plastic front (likely polypropylene) does not have established leaching issues under typical bakery storage conditions (room temperature, dry baked goods). Risk rises significantly if used with hot foods or extended contact with fatty items.
Ink or dyes on printed surfaces
No contamination reports exist for Westrock bakery bags; modern food-contact inks are regulated and typically safe. However, ink location (exterior only, typically) minimizes food contact.
The full breakdown
What it's made of and why it matters
This is a paper bag with a grease-resistant coating on the interior surface and a clear plastic window (likely polypropylene or cellulose). The grease-resistant coating type is not specified by Westrock, which is the core safety concern: such coatings historically used PFAS compounds (fluorinated chemicals) to repel oils and moisture. The clear front window is a separate plastic material that may leach if exposed to hot or fatty foods, though typical bakery use (room-temperature baked goods) keeps this risk low.
The brand's record and disclosure
Westrock, a major paper and packaging manufacturer, has not publicly disclosed the specific chemistry of its grease-resistant coatings or committed to PFAS-free formulations. The company has not published third-party certifications (such as FDA Food Contact Substance approval letters or PFAS-free pledges) for this product line. This silence on a widely known industry transition toward PFAS alternatives is a red flag for informed consumers.
How it compares in its category
Paper bakery bags with grease-resistant coatings are standard, but competitors increasingly disclose coating chemistry or offer PFAS-free alternatives (e.g., bags using silicone or non-fluorinated polymers). Westrock's lack of transparency puts this product behind the transparency curve, even if the actual coating is safe. Uncoated kraft paper bags without windows are a lower-risk alternative if appearance is not critical.
If you buy it
Use for room-temperature bakery goods only; avoid hot foods or prolonged contact with fatty items to minimize any potential leaching from coatings or the plastic window. Store in a cool, dry place away from direct heat or light. Do not microwave. Contact Westrock directly to request disclosure of the grease-resistant coating type and PFAS status before making this a regular purchase.
