Maxima Ultragreen Monofilament Fishing Line 35lb Green
Lower concern; nylon monofilament unlikely to contain PFAS.
Nylon monofilament line without known PFAS treatment or water-repellent coating. No lab testing available, but bare nylon monofilament presents lower PFAS risk than coated lines.

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.
Monomer leaching (caprolactam)
Nylon-6 can release trace caprolactam (the cyclic monomer) under warm or acidic conditions, though this is only relevant if line is heated or consumed, neither a typical fishing use. In normal outdoor freshwater or saltwater storage and use, leaching is negligible.
UV degradation and microplastic shedding
All nylon monofilament degrades and fragments under prolonged sunlight and mechanical stress; discarded fishing line is a known ocean plastic pollutant. Maxima line follows the same material behavior as all monofilament. This is an environmental concern, not a direct health hazard to the user.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Azo dyes in green colorant
Green monofilament requires colorants, typically organic pigments, which are screened for restricted azo compounds in modern manufacturing. No independent testing or regulatory action against Maxima Ultragreen has documented banned azo dyes; however, dye composition is proprietary and not disclosed publicly.
Heavy metals
Nylon monofilament colorants are applied as dry additives or pre-colored resin; modern fishing line producers avoid cadmium and lead-based pigments due to cost and liability. No recalls or testing data for Maxima line suggests metal contamination.
Source, FDA ↗PFAS
Nylon monofilament extrusion does not require PFAS-based water-resistant coatings or processing aids. Maxima has not been flagged in any PFAS testing or litigation; the material class itself carries lower PFAS risk than fluorocarbon line or treated textiles.

What it's made of and why it matters
Maxima Ultragreen is extruded nylon monofilament, a single continuous polymer strand used for fishing. Nylon (polyamide-6 or PA6) is a thermoplastic that does not require coatings, dyes, or adhesives that introduce typical chemical hazards in textiles or cookware. The green coloration is achieved through colorants mixed into the polymer before extrusion, a closed process with minimal leaching risk in freshwater or saltwater use.
The brand's record and disclosure
Maxima is a long-established fishing line manufacturer (part of the Berkley/Pure Fishing portfolio). The brand maintains no public PFAS disclosure statement, nor are there documented recalls or regulatory actions specific to Maxima monofilament products. Industry practice for monofilament production does not typically involve PFAS-based processing aids, and no independent testing has flagged Maxima lines as PFAS sources.
How it compares in its category
Nylon monofilament has lower concern regarding fluorinated compounds compared to fluorocarbon (which may contain or leach fluorinated compounds) or braided lines (which involve coatings and multiple adhesive layers). Maxima's 35lb test is a mid-range product with no known formulation differences from competitors like Berkley Trilene or Stren; the green dye is cosmetic and does not alter hazard profile versus clear monofilament.
If you buy it
Store spools in a cool, dry place away from direct sunlight to prevent UV embrittlement and discoloration (normal polymer aging, not chemical leaching). Nylon monofilament does not require washing or special maintenance before use. Replace line annually or after heavy use to maintain knot strength; older or sun-damaged line becomes brittle and loses integrity. Handle spool disposal as waste plastic; do not burn, as nylon releases nitrogen oxides when combusted.
