Open Farm Ancient Grains Small Breed Dry Dog Food
Dry pet food bags rarely use Teflon-family coating coatings; PFAS risk is lower but packaging composition remains undisclosed.
Open Farm's dog food comes in a standard kraft paper bag with polymer laminate. The brand makes no public disclosure about PFAS in packaging.

Why this grade
Category baseline

No PFAS disclosure
No public statement about PFAS in this product.
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 uses kraft paper outer layer with an unspecified inner polymer lining, a standard construction for dry pet food to provide moisture and oxygen barriers. The inner lining material (likely polyethylene, polypropylene, or nylon) is not publicly disclosed by the brand. Since the product contacts kibble (not water or acidic foods during storage), leaching risk from polymers is lower than for human food storage, but composition opacity prevents full assessment of potential additives in that lining.
The brand's record and disclosure
Open Farm is owned by Petropics and markets itself on natural and non-GMO ingredients for the food itself, but does not publicly disclose packaging material composition or certifications. No major recalls specific to packaging contamination have been reported for this line. The brand does not appear to have issued transparency statements about PFAS or other packaging chemicals, representing a gap in their disclosure standard compared to some competitors.
How it compares in its category
Dry pet food bags across brands typically use similar kraft-and-polymer constructions; Open Farm's approach is conventional. Competitors like Primal and Stella and Chewy offer similar or equally opaque packaging information. Some premium brands (e.g., The Farmer's Dog) use disclosed recycled or compostable materials, but Open Farm does not differentiate here. The lack of material transparency is common but not a market outlier.
If you buy it
Store the unopened bag in a cool, dry place away from direct sunlight to minimize any polymer degradation over time. Once opened, transfer kibble to an airtight glass or food-grade plastic container to reduce exposure to the inner lining. Do not expose the bag to heat sources or extended moisture. The bag is single-use; do not reuse it for other foods or liquids.
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.”
Polymer lining leachables (unspecified composition)
Inner lining material and additives (e.g., slip agents, antioxidants) are not disclosed. Risk of migration to dry kibble is low, but composition opacity prevents definitive assessment. No reported incidents for this product.
Printing inks or dyes on kraft exterior
Exterior printing may contain heavy metals or solvents, though standards for pet food bags are generally lower-risk than human food. No specific quality data available for Open Farm's printing practices.
Moisture or mold from paper deterioration
Kraft paper is permeable; if stored in humid conditions, the bag itself can degrade and allow moisture ingress, which could create an environment for mold on kibble. This is a storage issue, not a chemical hazard in the product itself.
BPA or BPS in polymer lining
No public reports of BPA or BPS in Open Farm bags. Dry kibble contact is lower-risk than for heated liquids, and pet food regulations do not mandate BPA-free claims. Lack of data does not mean absence of risk, only that no incidents are documented.
PFAS in polymer lining (non-Teflon-family coating)
Dry pet food bags rarely use Teflon-family coating coatings; PFAS risk is lower than in non-stick cookware or food packaging with water/grease barriers. Polyethylene or polypropylene linings are not known to contain PFAS, but composition remains undisclosed.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 58% 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.
