Iams ProActive Health Adult Lamb Rice Dry Dog Food
Lower concern for PFAS from bag material, but Iams does not publicly disclose PFAS testing or treatment avoidance.
Iams ProActive Health dry dog food comes in a standard kraft paper bag, which is not known to receive water/grease-resistant PFAS coatings in the dry pet food category. However, Iams/Mars Petcare has made no public PFAS commitment or disclosure about this product's packaging.

The full breakdown
What it's made of and why it matters
Iams ProActive Health dry dog food comes in a kraft paper bag, the industry standard for dry pet kibble. Kraft paper is unbleached or lightly bleached cellulose fiber with minimal chemical treatment required. The bag interior may have a thin plastic or wax barrier to protect against moisture and oxygen, but exposure of kibble to paper itself poses no known leaching risk for pet food applications.
The brand's record and disclosure
Iams (owned by Mars Petcare) does not publicly disclose PFAS testing, treatment avoidance, or third-party certifications for packaging materials. The brand has had isolated product recalls (mold, contamination) but none related to packaging material toxicity. No established pattern of disclosure on packaging chemical safety exists for this product line.
How it compares in its category
Kraft paper bags are the norm across dry dog food brands and carry lower contamination risk than multi-layer plastic or heavily coated papers. Competitors like Purina, Orijen, and store brands use identical kraft packaging. Iams offers no material differentiation or transparency advantage, nor disadvantage, versus mainstream rivals in this tier.
If you buy it
Store the bag in a cool, dry place away from direct sunlight to prevent kibble oxidation and moisture absorption. Check the kraft bag for tears or punctures before purchase and seal opened bags with a clip or airtight container to maintain freshness. Replace the bag every 4-6 weeks after opening; kraft paper breathability means kibble degrades faster than in rigid plastic. No special handling or material concerns apply.
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.”
Moisture and mold risk from kraft paper permeability
Kraft paper is porous and breathes; in humid environments, kibble inside can absorb moisture and develop mold. This is a storage issue, not a chemical hazard from the material itself.
Ink or dye migration from bag printing
Pet food bag inks are food-contact approved in the US and EU, but direct contact between kibble and outer printed surface is minimal. No recalls or reports link Iams bag printing to contamination.
Barrier coating leachables (if present)
Some kraft bags include a wax or thin plastic liner; food-grade formulations are required by regulation. No evidence of leaching into dry kibble or hazardous exposure in this product.
Paper dust or fiber fragments in kibble
Kraft bags are not treated to shed fibers into dry food. This is not a documented issue for pet kibble in standard kraft packaging.
Allergen cross-contamination from shared machinery
Kraft bags are manufactured on shared equipment across food and non-food products; allergen segregation depends on facility controls. Iams does not disclose supplier-level allergen protocols.
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.
