ECO- Lipak Wholesale Sugarcane Clamshell To-Go Boxes
Lower concern. Compostable sugarcane packaging rarely uses PFAS.
Sugarcane bagasse clamshells are inherently PFAS-low, with no known Teflon-family coating coatings. No brand disclosure on PFAS, but material type suggests minimal chemical treatment risk.

Category baseline
food packaging is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
The full breakdown
What it's made of and why it matters
These boxes are made from sugarcane bagasse, the fibrous residue left after sugar extraction, pressed and formed into rigid clamshell containers. Bagasse is a cellulose-based material with no synthetic polymers, so it avoids the plastic leaching risks (BPA, phthalates) common in petroleum-based food packaging. The material is inherently food-safe when processed without problematic additives, and its structure does not degrade easily into microplastics during normal use or microwave heating.
The brand's record and disclosure
Compostables brand maintains a silent stance on detailed PFAS testing and ingredient disclosure, which is typical for small compostable packaging manufacturers but limits transparency. No safety recalls, contamination reports, or regulatory actions are on record for this product line. The brand aligns with compostability certifications (likely BPI or equivalent), which imply third-party vetting of material safety, though certification does not guarantee absence of all chemical additives.
How it compares in its category
Sugarcane bagasse clamshells rank among the safest options for single-use food containers, ahead of conventional polystyrene (styrene leaching risk), PET (antimony catalyst residue), and coated paperboard (potential fluorinated coatings). They are comparable in safety to uncoated molded-fiber containers and superior to PVC clamshells (phthalate and chlorine concerns). The main trade-off is durability and grease resistance; bagasse absorbs liquids and may not perform well for oily foods without additional coating.
If you buy it
Use these boxes for dry or low-moisture foods at ambient to warm temperatures; they are microwave-safe but prolonged heating or contact with fatty/acidic foods may soften or discolor them. Store in a dry environment, as bagasse can absorb moisture and develop mold or mildew if left wet. Compost in a commercial facility if available, or dispose as compostable waste; home composting may take months. Replace boxes if visible mold, discoloration, or structural breakdown occurs.
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.”
Bleaching agents and residual processing chemicals
Bagasse pulp is typically bleached during processing; residual bleach (chlorine dioxide or hydrogen peroxide) or dyes may remain in the material. Food contact safety standards in most jurisdictions limit these to acceptable levels, but no public third-party testing of these specific boxes is available.
Coatings or waterproofing additives (non-fluorinated)
To improve grease and moisture resistance, bagasse clamshells are often coated with wax, clay, or synthetic polymers (polyhydroxyalkanoates). The brand does not disclose coating composition; unidentified coatings could include problematic additives, though fluorinated water repellents are less common in compostable-marketed products.
Mold and microbial contamination during storage
Bagasse is a natural fiber that readily absorbs moisture and can support mold growth if stored in humid or wet conditions. This is a practical hygiene risk, not a chemical hazard, but can contaminate food if boxes are used when visibly affected.
Microplastics from degradation
Bagasse does not contain or break down into microplastics because it is a natural cellulose fiber, not a synthetic polymer. This is a significant advantage over conventional plastics or mixed-material clamshells.
Heavy metals in adhesives or dyes
No public reports of heavy metal contamination in sugarcane bagasse food containers. Compostability certification standards typically screen for lead and cadmium in inks and adhesives, reducing this risk compared to unregulated packaging.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% 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.
