6 1/2" L x 1" W x 8" D - Pastry / Cookie Bag, Grease Resistant, White. Case of 1000.
Wait for coating composition disclosure; grease-resistant food packaging commonly uses PFAS-based treatments.
Duro Bag's pastry bags are marketed as grease-resistant without any disclosure of the coating chemistry. Grease-resistant paper and food-contact packaging historically rely on fluorinated compounds.

Material
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.
PFAS
Grease-resistant coating type is undisclosed. Industry standard for this application is PFAS-based, but Duro Bag does not confirm. Likelihood of PFAS presence is high; persistence and migration increase with product age, heat, and fatty food contact.
Source: ATSDR ↗Coating degradation and microparticle shedding
Paper bags subjected to moisture, heat, or mechanical stress (folding, transport) may shed coating particles. No published durability or wear testing data available for this product. Risk is low for single-use bakery application but increases if bags are reused or stored long-term.
Thermal stability of coating under heat
Grease-resistant coatings (whether PFAS or alternative) may degrade if exposed to direct heat, oven use, or steam. Product is not labeled for oven-safe or microwave-safe use. Coating breakdown can release additives into food and reduce barrier function.
What’s reassuring
Unlabeled adhesives or processing residues
Paper bags often use water-based adhesives and may be treated with processing aids. Duro Bag does not disclose these; however, no recalls or safety incidents are on record for this product line. Standard food-contact regulations likely apply.
The full breakdown
What it's made of and why it matters
This is a paper bag with a grease-resistant coating applied to the surface. The coating type is not specified by Duro Bag in available product literature, which is the core safety gap. Grease-resistant treatments in food packaging typically rely on either PFAS-based fluorochemicals (most common and most durable) or newer alternatives like polyhydroxyalkanoates or silicone. Without disclosure, you cannot determine whether this bag uses older high-persistence PFAS formulations or newer breakdowns. Paper itself is inert, but the coating is the hazard vector.
The brand's record and disclosure
Duro Bag Manufacturing has not made public commitments to PFAS phase-out or alternative coating disclosure on their website or product sheets reviewed. The company has not published third-party certifications (such as Cradle to Cradle, FDA compliance statements, or PFAS-free claims) for this product line. This silence is typical of mid-market food-service suppliers but represents a significant transparency gap for consumers seeking safer alternatives. No recalls or major contamination incidents are on record for this specific product.
How it compares in its category
Most single-use bakery bags on the market still rely on PFAS coatings because they offer superior water and grease repellency at low cost. Premium alternatives (e.g., bags certified PFAS-free or using wax or clay-based coatings) exist but typically cost 20-40% more per unit and are less common in bulk foodservice cases. Duro's product is a mainstream option with no better or worse safety profile than most competitors in its price tier, but that is the problem: the category as a whole lacks transparency.
If you buy it
Use these bags for immediate, short-term storage of baked goods at room temperature only. Do not microwave, freeze, or store foods with high fat content (nuts, oils, chocolate) for extended periods, as this can accelerate migration of coating residues into food. Replace the bag if visible wear, darkening, or grease saturation occurs; coating breakdown increases leaching risk. Request a product safety data sheet and coating composition from Duro Bag directly before large-scale or long-term use.

Duro Bag 25 lb Short Heavy Duty Kraft Grocery Bag
Unbleached kraft paper
Mold or microbial growth on stored paper
Limited concern
Lower concern as uncoated kraft is unlikely to contain PFAS, though Duro offers no transparency.
⚠Risky category by default
Duro Bag Manufacturing
Duro Bag 71010 Heavy-Duty Kraft Grocery Bag
kraft paper, uncoated or minimal treatment
Mold and microbial contamination
Limited concern
Lower PFAS concern; uncoated kraft bags rarely need fluorinated water or grease barriers.
⚠Risky category by default
If You Care
5 1/4" x 7 1/2" Kraft Bakery Bag w/ Clear Front
Kraft paper with unbleached cellulose; clear window (likely cellulose film or polyester); no added fluorinated treatment
Ink and dyes on printed surfaces
Limited concern
Cellulose film window degradation and microparticles
Limited concern
Adhesive or glue residues (window seal)
Limited concern
Mold and bacterial growth if moisture intrusion occurs
Limited concern
Lower concern as kraft plus clear window design avoids typical PFAS treatment.
