Tanimura & Antle · Food Packaging
Compostable Takeout Containers
Avoid until coating chemistry is disclosed; compostable containers often use PFAS barriers.
Plant-fiber compostable containers lack public disclosure of their waterproof coating. Industry-standard compostable packaging frequently uses fluorinated barriers like Teflon-type coating or PFOA alternatives to achieve grease and moisture resistance without lab verification.

What’s concerning
Waterproof / stain-resistant treatment
Water-repellent treatments have historically contained PFAS chemicals.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
Category baseline
food packaging is a category where PFAS exposure is more common.
PFAS
Fluorinated water-resistant coatings are standard in compostable takeout containers. Tanimura & Antle's silence on coating composition and the category's known PFAS prevalence suggest this product likely contains PFAS unless proven otherwise. Migration into fatty or acidic foods is possible, especially if stored warm or long-term.
Source: ATSDR ↗Other synthetic polymer or fluorinated additives in coating
Even if PFAS-free, undisclosed barrier coatings may contain other halogenated or synthetic compounds (e.g., polyurethanes, acrylates) that can leach under stress or heat. Without ingredient transparency, substitution risks cannot be ruled out.
Microplastic or particulate shedding from coating
If the barrier coating is polymer-based or synthetic, mechanical stress (cutting, folding, microwaving) or aging can cause the coating layer to flake or degrade into food. This risk is heightened for containers stored improperly or reused multiple times.
Incomplete industrial composability due to coating residue
Many compostable container coatings, especially fluorinated or synthetic barriers, fragment rather than fully biodegrade in standard industrial composting, leaving plastic-like particles in finished compost. This undermines the 'compostable' label's environmental value and may introduce microplastics into soil.
What’s reassuring
Bisphenol A or other phenolic compounds in adhesives or processing
No specific reports link Tanimura & Antle containers to BPA or BPS, but plant-fiber processing and coating application may involve phenolic or epoxy-based adhesives. Without material safety data sheets, this cannot be confirmed as absent.
The full breakdown
What it's made of and why it matters
Tanimura & Antle's compostable containers are constructed from plant-based fiber or pulp (likely sugarcane bagasse, wheat straw, or wood pulp) rather than foam or plastic. The critical unknown is the waterproof barrier coating applied to make them grease- and moisture-resistant. Plant fiber alone is porous and unsuitable for wet or oily foods without a sealant. The coating chemistry is not publicly disclosed by the brand, which is a major transparency gap in an industry where PFAS-based coatings are common.
The brand's record and disclosure
Tanimura & Antle, a produce distributor, has not issued public statements about the specific chemistry of their compostable container coatings, including whether PFAS, other fluorinated compounds, or synthetic polymers are used. The company has not obtained third-party certifications (such as OK Compost Industrial or certification from the Biodegradable Products Institute) that would typically require disclosure of coating materials. This silence in a product category where PFAS use is documented represents a significant red flag for informed purchasing.
How it compares in its category
Many major compostable takeout container brands (including World Centric and some retailers' private labels) have begun disclosing PFAS-free coatings or shifting to alternative barrier systems. However, industry-wide adoption of PFAS alternatives remains incomplete, and smaller suppliers like Tanimura & Antle's foodservice division have not matched this transparency. Plant-based fiber containers without PFAS barriers exist but are less common; most compostable options still rely on undisclosed or fluorinated coatings.
If you buy it
Before use, contact Tanimura & Antle directly to request written confirmation that the barrier coating is PFAS-free and specify which alternative sealant is used. Store containers in cool, dry conditions away from direct sunlight to minimize coating degradation. Do not use for foods heated above 70 degrees Celsius (158 degrees Fahrenheit) in the container itself, as heat can compromise the barrier and increase leaching risk. Compost only in industrial facilities that accept coated fiber; home composting may not break down the sealant layer completely.
