Koppers · Grease-Resistant Butcher Paper
Pospaper 1,000' 40# Butcher Paper Roll
Butcher paper lower concern; no PFAS claim but minimal risk inherent.
Standard butcher paper is bare kraft, not typically treated with PFAS. No brand disclosure on PFAS, but the material itself carries lower concern than coated food packaging.

The full breakdown
What it's made of and why it matters
Pospaper butcher paper is kraft paper, made from wood pulp via the Kraft process, which strips lignin and produces a mechanically strong, relatively pure cellulose sheet. This product is unbleached or minimally bleached, meaning it avoids the chlorine-based oxidation steps that historically introduced dioxins and other persistent contaminants into bleached papers. Kraft's inherent brown color comes from residual lignin; the material itself is inert under normal food-contact conditions and does not leach plastic additives or synthetic coatings.
The brand's record and disclosure
Koppers is primarily known for industrial wood treatment and railroad ties; limited public disclosure exists on food-packaging safety practices or third-party certifications for this specific product line. No major recalls or disclosed contamination incidents are on record for Pospaper butcher paper. The brand's silence on PFAS reflects a broader industry pattern where kraft paper manufacturers rarely volunteer testing data, though the material class itself carries inherently lower risk than plastic-coated or bleached alternatives.
How it compares in its category
Unbleached kraft butcher paper is a baseline-safe choice within food-wrapping materials, ranking well ahead of plastic-coated papers (which may contain fluorinated compounds) and chlorine-bleached variants. Pospaper's 40-pound weight is standard for heavy-duty meat wrapping and freezing, offering adequate grease resistance through lignin content without added synthetic barriers. It is functionally equivalent to generic butcher kraft from other commodity suppliers, with no premium certifications (like FSC or organic-grade) claimed or visible.
If you buy it
This product is safe for direct food contact including raw meat, poultry, and frozen items; no special precautions are needed beyond normal sanitation. Do not use at temperatures above 200C (92F would be irrelevant here, but use common sense for freezer storage or brief contact with warm food). The roll does not require special storage beyond a cool, dry environment; it is not water-resistant and will degrade if soaked. Replace if visibly torn, wet, or contaminated, and ensure it is stored away from strong odors or chemical fumes that kraft paper can absorb.
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.”
Bleach residues (chlorine compounds, dioxins)
Unbleached or minimally bleached kraft poses negligible risk. No testing on record for this specific product, but the material class avoids chlorine-oxidation steps that were historical sources of contamination in older bleached papers.
Heavy metals in inks or sizing
Food-contact kraft papers are not typically printed and do not carry inks. Pospaper is a plain roll with no visible print; sizing agents (clay, starch) used in kraft production are food-safe. No reported incidents.
Mineral oil or paraffin wax coating migration
Uncoated kraft does not rely on mineral oil for grease resistance; resistance comes from lignin. Some specialty butcher papers use food-grade wax, but Pospaper specifications do not indicate this. Confirm packaging labeling if wax-coating is a concern.
Mold or microbial contamination during storage
Kraft paper is hygroscopic and can support mold growth if stored in damp conditions. This is a handling and storage issue rather than manufacturing defect; keep rolls in a dry location and check for visible mold before use.
Formaldehyde or formaldehyde-releasing binders
Kraft pulping does not require formaldehyde-based resins. No binders or adhesives are typical in plain butcher paper rolls. No reports of off-gassing or odor issues specific to this product.
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.
