Fold-Pak Bio-Plus- Earth Take-Out Containers
Avoid until coating chemistry is transparent; grease-resistant fiber commonly uses PFAS.
Molded fiber marketed as eco-friendly typically requires water and grease barriers, often using fluorinated surfactants or PFAS compounds. This brand provides no coating disclosure or testing, leaving risk uncertain.

What Fold-Pak Bio-Plus- Earth Containers is made of, ingredients and materials
Fold-Pak Bio-Plus containers are molded from wood pulp fiber, a renewable alternative to plastic or foam. The pulp substrate itself poses minimal chemical hazard. However, these containers include a grease-resistant coating whose chemistry Biotrem has not publicly disclosed. Molded fiber coating technologies commonly rely on fluorinated compounds (PFAS) or wax-based systems; without transparency, the specific formulation cannot be assessed.
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.
PFAS
Molded fiber containers typically use Teflon-family coating or fluorochemical coatings for water and grease repellency. Biotrem's silence on coating chemistry and the product's intended use (takeout, greasy foods) make PFAS presence probable despite unconfirmed. This hazard is graded separately but remains the primary concern.
Source, ATSDR ↗Coating degradation and microparticle shedding
Repeated use, high temperatures, or acidic foods can compromise the integrity of polymer or wax coatings on molded fiber. Shed coating particles entering food are not well-studied in this product category, but degradation is a known failure mode for coated fiber containers.
What’s reassuring
Pulp residue and ink migration
Molded fiber is virgin or recycled wood pulp; no published recalls or hazard alerts for Bio-Plus specifically. Biotrem's use of recycled fiber is not disclosed, so ink residue or contamination from prior uses cannot be ruled out without material sourcing transparency.
Allergen or contamination from manufacturing
No documented allergenic additives, dyes, or antimicrobial treatments are publicly linked to Biotrem Bio-Plus containers. Standard molded fiber does not routinely include formaldehyde resins or heavy metals, but process water contamination or cross-contamination is a generic risk in food contact manufacturing.
How is this PFAS grade calculated?
The brand's record and disclosure
Biotrem markets Bio-Plus as an eco-alternative and emphasizes sustainability messaging, yet provides no publicly available safety data sheet, coating composition disclosure, or PFAS commitment. No third-party certifications (e.g., FDA verification of coating safety, NSF, or PFAS-free labeling) are documented for this product line. This silence on a material safety question is a red flag for molded fiber in the food service category, where grease resistance typically triggers PFAS use.
How it compares in its category
Molded fiber takeout containers occupy a middle ground between foam (known PFAS risk) and uncoated cardboard (no grease resistance). Competitors like Dart FormaGreen and some Biotrem alternatives do publish coating information or pursue PFAS-free certifications; Fold-Pak Bio-Plus's silent approach is notably weaker. Standard compostable plastics (PHA, PLA) pose different hazards but at least face more regulatory scrutiny on additives.
If you buy it
Reserve use for dry or room-temperature foods only; do not microwave or fill with hot liquids, as heat can accelerate coating leaching. Store containers in a cool, dry place away from direct sunlight to slow degradation. Inspect regularly for whitening, flaking, or odor changes signaling coating breakdown. Request a Safety Data Sheet from Biotrem before bulk purchase; a transparent response strengthens confidence in the product.
