Open Farm Grass-Fed Beef Dry Dog Food
Lower concern for PFAS; dry pet food packaging typically avoids fluorochemicals, but no brand transparency.
Open Farm's dog food bag is standard paper/cardboard packaging without obvious grease-resistant or water-repellent coatings that would trigger PFAS use. The brand makes no public PFAS claims and provides no third-party verification.

The full breakdown
What it's made of and why it matters
Open Farm Grass-Fed Beef is packaged in a multi-layer paper and cardboard bag with standard food-grade printing inks. Paper-based pet food packaging avoids many plastic leaching pathways (no BPA, phthalates, or degradation-related microplastics) because dry kibble has minimal moisture contact and zero heating risk. The primary exposure vectors are printing ink migration and any adhesives used in bag construction, both tightly regulated for food contact in North America.
The brand's record and disclosure
Open Farm (owned by Petropics) does not publicly disclose detailed packaging material sourcing or third-party testing of bag components. The brand has not issued statements on PFAS avoidance in packaging, though dry pet food bags are not a known vector for intentional fluorochemical application. No major recalls attributable to bag contamination or ink toxicity are on record for this product line as of available public data.
How it compares in its category
Paper-bag dry pet food is the industry standard and typically carries lower chemical hazard than plastic-film alternatives (which may contain additives and face heat/humidity-driven degradation). Open Farm's packaging is visually similar to competitors like Primal, Stella & Chewy's, and most mainstream premium dry dog foods. Paper bags do not offer the moisture barrier of plastic, so storage conditions matter more; this is a usability trade-off, not a safety one.
If you buy it
Store the opened bag in a cool, dry place and transfer kibble to an airtight container after opening to prevent staleness and moisture ingress. Paper bags degrade faster than plastic, so check for visible tears, mold, or off-odors before feeding. Use within 6-8 weeks of opening for optimal freshness. No special handling or heat precautions are needed for the bag itself, as dry kibble poses no chemical leaching risk.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Printing ink migration
Paper bags use food-contact approved inks, but direct contact between ink and kibble surface is theoretically possible if bags are stacked or compressed. FDA and Health Canada regulate food packaging inks; no specific incidents reported for Open Farm bags. Risk is minimal under normal storage.
Adhesive residues in bag seams
Paper bag construction uses food-grade adhesives, which are not typically a concern for dry pet food because kibble does not leach solvents or moisture that would activate adhesive migration. No recalls or safety alerts specific to Open Farm bags on record.
Mold or bacterial growth from moisture
Paper bags have lower moisture barrier than plastic. If stored in humid environments or if bags are punctured, mold can develop on kibble. This is a storage and freshness issue, not a packaging toxicity issue, but can pose GI upset to pets.
Heavy metals in ink pigments
Food packaging inks in North America are regulated to exclude lead and cadmium. No independent testing of Open Farm bag inks is publicly available, but the regulatory framework and lack of reported incidents suggest minimal concern.
Formaldehyde in bag coatings or sizing
Paper bags may use formaldehyde-based sizing or coatings in manufacture. However, formaldehyde is not typically detected on the exterior food-contact surface and off-gasses from paper at negligible levels, especially in dry product environments. No incidents reported for this product.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
