Purina Pro Plan Sensitive Skin Stomach Salmon Rice Dry Dog Food
Lower risk for typical dry pet food bag, but coating details remain unconfirmed.
This Purina Pro Plan dry dog food bag is standard kraft paper that likely has a grease-resistant interior lining, though Purina doesn't disclose the coating type or PFAS status. No public lab testing or PFAS-free certification exists for this packaging.

What Purina Pro Plan Sensitive Dry Dog Food is made of, ingredients and materials
Purina Pro Plan Sensitive Skin Stomach comes in a kraft paper bag with an interior coating designed to repel moisture and fats from the kibble. The coating composition is not publicly disclosed by Purina, which is standard industry practice for this product type. Kraft paper itself is food-safe and widely used for dry pet foods; the internal barrier prevents oil migration into the outer bag and maintains product freshness. The unspecified coating is the primary unknown factor, though grease-resistant coatings on pet food bags typically include waxes, polyethylene, or other standard food-contact polymers.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Unidentified interior coating composition
The specific chemical identity of the grease-resistant interior coating is proprietary and not disclosed. While standard food-contact polymers have lower concern under current regulations, lack of transparency prevents independent verification that the coating does not contain unreported additives or migrate into kibble over time.
Moisture-driven bag degradation and mold risk
Kraft paper can absorb humidity and degrade structurally, potentially compromising the interior coating seal. In high-humidity storage conditions, this may allow mold growth on kibble or allow the coating to separate, though this is a usage and storage issue rather than a manufacturing defect.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Lipid oxidation and rancidity from bag exposure
The salmon-based kibble contains fats that can oxidize if exposed to oxygen over extended storage. The kraft bag's permeability is normal for dry pet food and does not pose a acute safety hazard, though it may reduce product freshness.
Ink or printing residues on bag exterior
Purina bags use standard food-grade inks for labeling and branding. No reports of ink migration into the kibble or toxicity from exterior contact have been documented, and exterior inks do not contact the food directly.
Cross-contamination from bag handling or storage
The bag itself does not introduce chemical hazards, but improper storage near chemicals, pesticides, or non-food items could secondarily contaminate kibble. This is a usage and environment issue, not a product defect.
How is this PFAS grade calculated?
The brand's record and disclosure
Purina Pro Plan is owned by Nestlé and has no widely publicized recalls specifically for bag material hazards or coating leaching. Purina does not voluntarily disclose the exact composition of bag interior coatings, citing proprietary formulation. The brand meets FDA compliance for pet food contact materials but does not pursue third-party certifications for bag safety. No credible reports of consumer or pet harm from this product's packaging have been documented in public records.
How it compares in its category
Pet food bags are among the lowest-risk food packaging categories because the product is not heated in the bag and exposure time is typically brief (weeks to months). Most major pet food brands use similar kraft-paper-plus-coating designs without public safety incidents. Some premium brands (e.g., certain Orijen or Acana products) explicitly state they use polyethylene or food-grade wax coatings, offering marginally more transparency. For a mass-market dry pet food, this product's bag design is typical and carries no higher hazard profile than competitors.
If you buy it
Store the bag in a cool, dry place after opening; transfer kibble to an airtight plastic or glass container if you keep the bag open for more than a few weeks to prevent oxidation and pest entry. Do not heat the bag or its contents, and avoid storing directly on damp surfaces where the kraft exterior could absorb moisture and degrade. Inspect the bag for tears or grease stains that might signal coating failure; if the interior is visibly wet or the kibble appears rancid, do not use. Dispose of bags in recycling if local programs accept kraft packaging; the coating does not typically prevent recyclability.
