OPEN FARM Ancient Grains Grass Fed Beef Dry Dog Food

C · Moderate

Lower concern for typical pet food packaging; no evidence of deliberate PFAS use, but standard PE liners are not verified PFAS-free.

Verdict: BuyPet food bag with standard kraft/PE construction; no established safety concerns beyond typical packaging; brand transparency limited but product category poses minimal inhalation or direct-contact risk.

Open Farm's dry dog food bag uses standard kraft paper with polyethylene film lining, common pet food packaging with no known PFAS triggers (no grease resistance, waterproofing, or nonstick claims). The brand makes no PFAS disclosure.

The full breakdown

What it's made of and why it matters

Open Farm's packaging uses kraft paper (outer layer) bonded to a polyethylene (PE) plastic liner (inner layer). This is the industry standard for dry pet food to provide moisture and oxygen barriers while keeping contents fresh. PE itself is chemically stable and FDA-cleared for food contact in the US. The concern arises only if the PE liner degrades, is heated excessively, or contains non-standard additives; for dry kibble stored at room temperature, risk is minimal.

The brand's record and disclosure

Open Farm (owned by Petropics, part of the Petropics Company family) markets itself as a premium, natural pet food brand with emphasis on grass-fed sourcing and ingredient transparency. However, the brand has not published detailed packaging material safety statements or PFAS verification on record. No major recalls or packaging-related safety incidents have been established for this product line. The company's silence on PFAS in packaging is typical of smaller pet food manufacturers; it does not indicate deliberate use, but rather lack of third-party verification.

How it compares in its category

Kraft/PE bag construction is universal across mainstream and premium dry pet food brands; Open Farm does not differentiate here. Some competitors (e.g., higher-end brands) use compostable or recyclable kraft-only bags without PE liners, though these are less effective moisture barriers. Open Farm's approach is neither better nor worse than competitors like Orijen, Acana, or Stella & Chewy's in terms of packaging safety. The real differentiator remains ingredient quality and sourcing, which is outside packaging safety scope.

If you buy it

Store the bag in a cool, dry place away from direct heat and sunlight; do not leave open bags near heat sources or in direct sun, as this can accelerate PE degradation. Transfer kibble to airtight glass or metal containers after opening if you plan storage beyond 2-3 weeks, both to preserve freshness and minimize any theoretical microplastic migration. Inspect the bag for visible tears, punctures, or ink leaching before purchase. Wash your hands after handling the bag, especially if contents have been in contact with soil or moisture.

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.”

Possible

Polyethylene (PE) liner degradation and microplastic migration

PE liners can degrade under heat, light, or physical stress, theoretically releasing plastic fragments into kibble. For dry pet food stored at room temperature in intact bags, this risk is low; however, risk increases if bags are punctured, stored near heat, or exposed to sunlight over months. No recalls specific to Open Farm's PE liner have been documented.

None known

Ink and adhesive leaching from bag printing

Kraft paper bags are printed with branding and ingredient lists using food-safe inks, which are regulated by the FDA. Open Farm does not appear on recall lists for ink-related contamination. Risk is minimal provided the exterior ink does not directly contact kibble and the bag remains intact.

Possible

Moisture and mold in compromised bags

If the PE liner is punctured or the bag seal is compromised, moisture can enter and facilitate mold or bacterial growth in kibble, which poses a food safety risk to pets. This is a handling and storage issue rather than a manufacturing defect, but remains relevant to safe use.

None known

Heavy metals or contaminants in kibble (ingredient-related, not packaging)

Open Farm markets grass-fed beef and organic/natural ingredients. No testing reports or recalls for lead, cadmium, or other heavy metals in this product line are on public record. Pet food is regulated by AAFCO and the FDA; Open Farm's ingredient sourcing claims are not independently verified on the packaging safety level.

None known

Allergen cross-contamination or labeling accuracy

Open Farm does not have an established pattern of allergen labeling failures or cross-contamination recalls for this product. The ingredient list is printed on the bag; accuracy depends on manufacturing controls, not packaging material. No specific incidents reported.

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.
