What Bio Pack To-Go Containers - 6 pack Small is made of, ingredients and materials
Bio Pack To-Go containers are molded from compostable pulp or fiber (likely sugarcane bagasse or similar plant waste), which is food-safe when uncoated. The critical unknown is the water-resistant coating applied to the interior and exterior. The brand does not publicly specify whether this coating uses PFAS-based fluorochemicals, wax, or other sealants. The coating's chemical identity directly determines leaching risk into food, especially hot or fatty items.
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.
Water-resistant coating leachables (unspecified chemistry)
The interior coating formulation is not disclosed by the brand. Leaching into food is possible with heat, fat, or acidic contents, but cannot be assessed without knowing whether the coating is PFAS-free, wax-based, or synthetic polymer.
Microplastic release during heating or degradation
If the water-resistant coating is a synthetic polymer (rather than natural wax or bioplastic), heating or physical stress may cause microplastics to shed into food. The pulp substrate itself does not shed microplastics.
Contamination from mold or bacterial biofilm if pre-wetted or stored damp
Porous fiber containers retain moisture more readily than plastic. If stored in humid conditions or wet before use, fungal or bacterial growth is possible. This is a use and storage issue rather than a formulation hazard.
What’s reassuring
BPA & bisphenols
Compostable pulp containers do not inherently contain BPA or phthalates. However, if adhesives or processing aids were used in molding, trace contamination is theoretically possible. No testing or complaints are on record for Bio Pack products.
Source, FDA ↗Formaldehyde / VOCs
Formaldehyde-based resins are used in some paper and pulp products for strength and water resistance. The brand does not disclose use of such resins. No independent testing or recalls confirm their presence, but absence of disclosure is a gap.

The brand's record and disclosure
The brand maintains a public commitment to compostable and sustainable packaging but does not publish detailed material safety data sheets or coating composition on their website or product labeling. No independent recalls, safety complaints, or certifications (such as OK compost or FDA approval statements) are on record for this specific product line. The brand's silence on PFAS and coating chemistry represents a disclosure gap rather than confirmed absence of concern.
How it compares in its category
Compostable fiber containers are marketed as alternatives to plastic-lined paper and expanded polystyrene with lower concern regarding certain chemical classes. However, they typically underperform plastic in barrier properties, necessitating a water-resistant coating whose safety depends entirely on formulation. Most established compostable container brands (such as World Centric or Footprint) disclose coating type (e.g., plant-based PHA or food-grade wax). Biopac's lack of transparency places it below peer standards for consumer trust.
If you buy it
Contact directly and request written confirmation that the water-resistant coating does not contain PFAS or other fluorochemicals. Avoid prolonged contact with hot (above 60 degrees Celsius) or fatty foods (oils, sauces, dressings) until coating safety is verified. Use for ambient or cool foods when possible. Check that containers are fully composted after use; if local composting is unavailable, disposal as waste may leave residual coating in landfill.
