Open Farm Harvest Chicken & Ancient Grains Dry Dog Food
Lower-concern dry food packaging, but no brand transparency on coating treatments.
Open Farm's chicken & grain kibble comes in a standard dry-food paper bag. The primary concern is the interior lining/coating, typical pet food bags may use water-resistant treatments, but Open Farm makes no public disclosure of PFAS-free status or coating composition.

Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
Open Farm Harvest Chicken dry dog food comes in a multi-ply kraft paper bag with an interior plastic film lining, a standard format for dry pet foods. The lining prevents moisture ingress and grease migration into the paper outer layer. No unusual material composition is documented for this product; the bag design is consistent with mainstream dry kibble packaging across the category.
The brand's record and disclosure
Open Farm (owned by Petropics) markets itself as a premium, natural pet food brand and maintains certifications including AAFCO approval for complete and balanced nutrition. The brand has not disclosed detailed information about PFAS-free or fluorinated coating treatments on its packaging. No major recalls or contamination incidents specific to this product line are on public record as of recent data.
How it compares in its category
Dry dog food bags typically use kraft-plastic laminate construction; Open Farm's packaging is conventional in this respect. Many premium and budget brands use identical lining materials without documented safety gaps. This product does not stand out as having either superior or inferior packaging safety compared to similar grain-inclusive kibbles.
If you buy it
Store the unopened bag in a cool, dry place away from direct sunlight to preserve the lining integrity and prevent moisture ingress. After opening, transfer kibble to an airtight glass or hard plastic container to prevent rancidity and protect against pest contamination. Inspect the bag interior for any visible tears or damage; discard if the lining is compromised. Do not microwave or heat the bag itself.
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.”
PFAS in bag lining coating
Kraft bags with plastic film linings may contain fluorinated coatings to improve grease and moisture barriers. Open Farm has not disclosed coating treatment; assumed to follow industry standard, which often includes fluorine-based polymers. No recall or contamination report exists for this specific product.
Plastic film degradation and microplastic migration
Interior plastic lining can degrade over extended storage, especially if exposed to heat, light, or oxidation. Microscopic film fragments could theoretically contaminate kibble if the lining is severely compromised, though this requires visible damage. Standard storage conditions limit this risk.
Ink or adhesive residues on exterior paper
Open Farm bags use standard food-grade printing inks and adhesives approved for pet food contact. No documented contamination from printing materials in this product line. Risk is low with normal handling.
Bacterial or mold growth if bag seal is broken
Dry kibble is low-moisture and shelf-stable, but if the bag lining is torn or seal is compromised, moisture ingress can promote mold or bacterial growth. This is a storage and handling issue, not an inherent product defect.
Heavy metals in kibble formulation (not packaging)
Open Farm Harvest Chicken is formulated with named meat sources and grains. No reports of heavy metal (lead, cadmium, mercury) contamination in Open Farm products. AAFCO oversight and multi-batch testing by pet food manufacturers generally detect major contaminant issues.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 62% 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.
