Avant Grub Biodegradable 6x6 Take Out Food Containers with Clamshell Hinged Lid Mi
Lower concern. Plant-based packaging rarely PFAS-treated, but no verification.
Springpack's bagasse containers are inherently lower PFAS risk due to plant fiber material. No brand disclosure on PFAS, and no third-party testing available to confirm.

Why this grade
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
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
Bagasse is fibrous plant pulp left over from sugarcane processing, pressed and molded into rigid clamshells. Unlike polystyrene or PET, it contains no petroleum-derived plastics, so it avoids leaching of BPA, BPS, or phthalates into food. The material is inherently compostable and biodegradable, which reduces long-term environmental burden. However, bagasse is porous and may retain moisture or absorb odors, and its structural integrity degrades faster than synthetic alternatives when exposed to heat or prolonged moisture.
The brand's record and disclosure
Springpack has minimal public safety transparency; no major recalls or documented safety violations are on record for this product line. The brand makes no explicit claims about PFAS-free status or third-party testing, which is typical for smaller bagasse container suppliers. No certifications such as FDA direct contact approval or compostability standards (BPI, OK Compost) are evident in available product labeling, leaving verification gaps for food-contact safety.
How it compares in its category
Bagasse clamshells occupy a middle position: safer than polystyrene foam (which can leach styrene) or unlined PET (potential antimony catalyst residue), but less documented than rigid PLA or molded fiber with explicit food-contact certifications. Many competing brands (such as World Centric or Footprint) provide compostability certification; Springpack's product lacks visible third-party assurance. Cost and compostability are trade-offs for reduced hazard transparency.
If you buy it
Use for cold or room-temperature foods; avoid prolonged contact with hot foods above 140F, as bagasse softens and may shed fibers. Do not microwave, as high heat may degrade the material and leach unidentified residues. Replace containers if you notice visible mold, odor absorption, or structural weakening (softening, cracking). For best safety, allow containers to dry fully between uses if reused, and compost per local guidelines rather than landfilling.
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 and processing chemicals
Bagasse pulp is typically bleached and chemically processed during molding. No testing on record for residual chlorine compounds or other processing agents in Springpack containers; industry standard practices vary widely.
Mold and microbial growth
Bagasse is porous and hygroscopic; if containers are stored damp or in high-humidity conditions before use, mold or bacterial biofilm can develop. Springpack labeling does not specify moisture-control packaging or antimicrobial treatment.
Fiber shedding when heated
Bagasse integrity degrades under sustained heat (above 140F). Hot foods or microwave use can cause fibers to flake into food; this is a known limitation of plant-fiber clamshells, not specific to Springpack but inherent to the material class.
Heavy metals or dyes in coatings
Bagasse containers typically have no plastic or synthetic coatings, so cadmium, lead, or azo dyes are not expected. No safety incidents or testing data contradict this for Springpack products.
Adhesive or ink migration from labels
If labels are glued or printed directly onto the container interior, solvents or adhesive components could leach into food. Springpack labeling does not specify label placement or ink composition; this depends on how units are finished.
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.
