Maxima Ultragreen One Shot Fishing Line
Lower concern; standard nylon monofilament has no documented PFAS need, but no brand disclosure available.
Maxima Ultragreen One Shot is a nylon monofilament fishing line with no public evidence of Teflon-family coating coatings or PFAS-based treatments. The brand makes no PFAS claims either way.

The full breakdown
What it's made of and why it matters
Maxima Ultragreen One Shot is extruded nylon monofilament, a single continuous polymer strand with no coatings, dyes, or additives visible in standard product documentation. Nylon 6 monofilament is chemically inert in water and does not leach monomers or degradation products under normal fishing conditions. The 'green' coloration is achieved through disperse dyes incorporated during extrusion; these are standard textile-grade dyes not known to migrate into water under use.
The brand's record and disclosure
Maxima is a legacy fishing-line manufacturer (founded 1971) with no public recalls, safety certifications, or environmental disclosures specific to this line on record. The brand does not publish material safety data sheets or third-party testing results for monofilament products. No controversies regarding chemical safety or PFAS use have been documented for Maxima monofilament in available sources.
How it compares in its category
Monofilament nylon fishing line is among the safest synthetic fishing materials from a toxicology perspective. Most competitors (Berkley, Seaguar, Suffix) use identical nylon monofilament chemistry and offer no superior chemical transparency. Some brands promote fluorocarbon alternatives, which carry no added hazard over nylon but cost more; braided lines introduce microfiber shedding concerns absent in solid monofilament.
If you buy it
Store spools in cool, dry conditions to slow UV and hydrolytic degradation of nylon. Replace line annually or after 50 to 100 hours of use, as tensile strength decays from UV and mechanical stress, not chemical leaching. No special handling is required; monofilament poses no skin or inhalation hazard during casting or knot-tying. Dispose of spent line in trash or (ideally) fishing-line recycling programs; it does not biodegrade quickly in water.
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.”
UV and hydrolytic degradation of nylon polymer
Extended sun exposure and water immersion degrade nylon backbone over months, releasing small oligomers and monomers (caprolactam, hexamethylene diamine) into water at trace levels. This is inherent to all nylon monofilament and not unique to Maxima; no documented health impact from fishing-line degradation in freshwater or saltwater.
Disperse dye migration from green colorant
Disperse dyes used in monofilament extrusion are chemically bonded to the nylon polymer and do not migrate significantly into water under normal pH and temperature. No Maxima-specific data exists, but azo-dye toxicity concerns apply to textiles, not solid-phase polymers with covalent dye bonding.
Microplastic shedding
Monofilament can fragment during casting, knot-tying, and fish-handling, creating microplastics (1-5 mm particles) that enter aquatic environments. This is a ecological concern, not a direct consumer toxicology issue, but relevant to overall product safety profile and disposal practice.
Tensile failure and lability during use
Monofilament brittleness increases with age and sun damage, raising risk of line snap and fish-hook ejection into the angler's face or body. This is a mechanical hazard, not a chemical one, but material degradation is well-documented across all nylon monofilament brands including Maxima.
Lack of material safety disclosure
Maxima publishes no safety data sheets, chemical composition guarantees, or third-party testing for this product. Without independent verification, trace heavy metals or processing residues in the polymer cannot be ruled out, though standard nylon extrusion does not introduce regulated hazards.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 70% 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.
