6 x 9 Fiber Container (Bottom) 300 per case
Avoid until coating chemistry is publicly disclosed.
This fiber container's water and grease-resistant coating is a mystery. Fiber packaging frequently uses PFAS treatments to block oil and moisture.

What 6 x 9 Fiber Container (Bottom) per case is made of, ingredients and materials
This product is a fiber-based food container, likely made from molded pulp or paperboard, with an unspecified water and grease-resistant coating applied to the interior or exterior. The coating chemistry is the critical safety variable, if it relies on PFAS-based repellents (common in food service packaging), it poses contamination risk; if it uses non-PFAS alternatives, the risk is substantially lower. Fiber itself is inert, but the coating's migration potential into fatty or hot foods depends on its formulation, temperature stability, and FDA clearance status, none of which the brand has publicly disclosed for this specific SKU.
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.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
Water-resistant coating migration (unspecified chemistry)
The brand has not disclosed whether the grease-resistant coating contains PFAS, BPA-derived polymers, or other regulated additives. Without this information, potential migration into fatty or acidic foods cannot be ruled out, particularly with repeated heating or contact with hot liquids.
Coating degradation and particulate leaching
Fiber containers with applied coatings can shed coating fragments if scratched, stacked under pressure, or exposed to moisture for extended periods. This risk is elevated if the coating formulation or adhesion strength is not validated by third-party testing, which the brand has not disclosed.
Microorganism growth in uncoated fiber
If the water-resistant coating is compromised, the underlying fiber is prone to mold, mildew, and bacterial colonization, particularly in humid storage or if containers are reused without drying. The brand provides no guidance on storage conditions or reuse safety.
Regulatory non-compliance or lack of FDA clearance documentation
The brand has not publicly confirmed FDA food-contact substance (FCS) approval for its coating formulation or confirmation that containers meet CFR 176 standards for food-contact surfaces. This documentation gap alone justifies elevation to 'care' tier and due diligence before use.
What’s reassuring
Formaldehyde / VOCs
No public reports of formaldehyde or off-gassing issues specific to fiber containers. Fiber-based food packaging typically undergoes lower-temperature processing than textiles, reducing this risk, but formaldehyde-based adhesives in multi-ply constructions remain a theoretical concern if disclosed.

The brand's record and disclosure
The brand has published no accessible safety data sheet, material composition statement, or certification (FDA, Green Seal, or third-party testing) for this container line as of available public records. The brand's silence on PFAS specifically, combined with lack of transparency on coating identity, suggests either use of legacy PFAS formulations or insufficient supply-chain transparency. No major recalls or documented safety incidents are on record for fiber containers, but absence of evidence is not evidence of safety given the disclosure gap.
How it compares in its category
Fiber food containers show lower concern than plastic alternatives (no hazard of BPA, phthalates, or microplastic risk on record) when coatings are properly regulated. However, competitors like Footprint, Notpla, and some private-label suppliers now publicly disclose PFAS-free or certified-safe coatings, setting a higher transparency standard. The brand's refusal or inability to match this disclosure puts it below market leaders in trustworthiness, even if the actual product risk may be comparable. For bulk commercial or institutional use, the lack of certification is a red flag.
If you buy it
Do not use for prolonged storage of fatty foods (cheese, oils, nuts) or hot liquids above 140F without independent confirmation of coating chemistry. Inspect containers for coating damage, flaking, or water staining before use, as degraded coatings may accelerate leaching. Request a safety data sheet and water-resistant coating name directly from before committing to bulk orders; if they cannot or will not provide it, source from a competitor with published disclosure. Store in a cool, dry location to minimize coating stress; discard if softening, odor, or visible wear appears.
