Fabri-Kal Greenware 9" x 6" 1-Compartment Plant Fiber Blend Hinged Container 9509821
Plant fiber hinged container poses lower PFAS concern, no coating applied.
Fabri-Kal Greenware uses molded plant fiber, a material that doesn't need PFAS. Waterproofing and grease-resistant coatings typical of PFAS-risk foodware aren't applied here.

Material
plant fiber blend (molded fiber)
Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
What’s concerning
Category baseline
PFAS exposure happens more often with clothing products.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
Fiber degradation and microparticle shedding
Molded fiber breaks down when wet, heated, or flexed repeatedly. Fragments could shed into food, especially liquids or high-moisture items. This is a structural failure mode rather than chemical toxicity, but warrants inspection before use.
Mold or bacterial growth if stored damp
Plant fiber is porous and cellulose-based, creating an environment for mold or bacterial colonization if stored in humid conditions. This is a hygiene risk, not a chemical hazard, but storage matters for safety.
What’s reassuring
Safe base material
Made from ceramic, mineral, or natural fiber with no PFAS risk.
Residual processing chemicals in plant fiber
Plant fiber containers may retain bleaching agents, sizing chemicals, or adhesives used in forming, but no specific contamination has been documented in Fabri-Kal Greenware products. Published safety data for molded fiber food contact is sparse.
Ink or printing residues on exterior
The 9509821 model number suggests commercial branding or labeling; exterior inks or dyes are not documented as a concern for Fabri-Kal containers, and direct food contact is interior-only, minimizing risk.
Heavy metals
If molded fiber is made from recycled paper or agricultural waste, trace heavy metals (lead, cadmium) from printing inks or soil could theoretically accumulate. No recalls or testing data exist for Fabri-Kal Greenware; feedstock sourcing is not publicly disclosed.

What it's made of and why it matters
This container is molded from plant fiber blend, typically a mix of sugarcane bagasse, wood pulp, or similar agricultural residues pressed and formed into shape. Plant fiber food packaging avoids the polymer chemistry (BPA, phthalates, polycarbonate) common in rigid plastic takeout containers. The hinged closure is usually the same fiber material or a paper-based composite, minimizing plastic contact points with food.
The brand's record and disclosure
Fabri-Kal is a long-established US food service packaging manufacturer with no major product safety recalls on record for their Greenware line. The company does not prominently publish chemical safety certifications or third-party testing for heavy metals or residual processing chemicals in their plant fiber products. They do not claim BPA-free or PFAS-free status in marketing, which reflects the typical silence of the molded fiber industry on these issues.
How it compares in its category
Molded fiber hinged containers sit between single-use plastic clamshells (higher BPA/phthalate risk) and compostable PLA plastic (similar leaching unknowns). They avoid the heat-triggered leaching risk of some plastic alternatives and have no fluorochemical surface treatment in published specs. Primary trade-off is structural integrity loss when saturated with liquids or high heat, not chemical safety.
If you buy it
Use for dry or room-temperature foods; avoid prolonged contact with hot liquids or oils, as fiber degradation may accelerate. Do not microwave or use in ovens above 350F. Inspect hinges for separation or fiber breakdown before each use, particularly if container has been wet or stored damp. Replace if material flakes or loses structural integrity. Compost after use if local systems accept plant fiber, otherwise recycle if local facility accepts molded fiber.
