Komax Biokips Food Storage Bowls Set-of-4 Round
Lower PFAS concern; standard food storage plastic with no known Teflon-family coating coatings, but brand discloses nothing.
Komax Biokips bowls are injection-molded polypropylene food containers without reported nonstick or water-resistant coatings that would typically trigger PFAS use. The brand makes no PFAS claims or disclosures.

Why this grade

No PFAS disclosure
No public statement about PFAS in this product.
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
Komax Biokips bowls are polypropylene (PP, #5 plastic), a thermoplastic polymer chosen for food storage because it resists cracking and has a higher melting point than PET or HDPE. PP does not contain BPA or phthalates by design. The main chemical risk with PP is leaching of oligomers or additives (like slip agents or UV stabilizers) if the plastic is exposed to high heat or solvents, though at temperatures typical of food storage and dishwashing, this risk is minimal.
The brand's record and disclosure
Komax is a Canadian houseware manufacturer with no major public safety recalls or controversies on record for food storage containers. However, the brand provides no published PFAS statement, third-party certifications (such as FDA compliance letters or BPA-free verification), or detailed ingredient disclosure for colorants or processing aids. This silence is not unusual for mid-market plastic tableware makers but means independent verification of safety claims is limited.
How it compares in its category
Polypropylene food storage containers are among the safest plastics for food contact; they rank favorably against PET (#1), which can leach antimony, or polycarbonate, which historically contained BPA. Komax Biokips sits in the standard mid-range of durable plastic container sets. Comparable brands (Rubbermaid, OXO, Sistema) offer similar material and comparable transparency gaps; Pyrex glass alternatives carry no plastic leaching risk but are heavier and breakable.
If you buy it
Do not microwave contents in these bowls unless the lid is removed; PP softens at approximately 160 degrees Celsius and may warp under prolonged microwave use. Hand wash or use a cool dishwasher cycle to extend life. Replace containers if cracks or cloudiness appear, as degraded plastic can shed particles. Store food at room temperature or in a cool cabinet; avoid prolonged contact with hot oils or acidic foods, which may accelerate minor leaching of additives.
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.”
Oligomer and additive leaching from polypropylene
PP can release small-molecular-weight compounds (lubricants, antistatic agents, or colorant precursors) under heat or mechanical stress. Risk is low under normal storage and dishwashing conditions but increases if containers are reused for hot liquids or heated in a microwave repeatedly.
BPA / BPS contamination
Polypropylene is not formulated with BPA or its substitutes by material design. No recalls or reports of BPA in Komax Biokips containers exist. Risk is negligible for this resin type.
Phthalate plasticizers
PP does not require phthalate plasticizers for flexibility. Standard food-grade PP formulations used in rigid containers do not contain phthalates. No evidence suggests Komax uses phthalates in this product line.
Microplastic shedding from wear or degradation
Repeated washing, UV exposure, or thermal cycling can degrade PP over years of use, potentially releasing microplastics into food or the environment upon disposal. Cracks, cloudiness, or surface scratches are signs of beginning degradation and warrant replacement.
Heavy metal pigments in colored plastics
If the bowls are colored (common in Biokips sets), the pigments used are not disclosed publicly. Historical industry practice included cadmium or lead in some colored plastic products, though modern food-contact plastics are typically pigmented with safer iron oxides or organic dyes. No specific reports exist for Komax Biokips, but brand transparency would reduce uncertainty.
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.
