Berkley Trilene XT Solar Monofilament Service Spool
Standard nylon fishing line with no documented PFAS risk.
Nylon monofilament without documented PFAS treatment. No brand disclosure on PFAS, though lower concern than coated or waterproofed products.

Material

Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
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.
Nylon degradation and microplastic shedding
UV exposure and mechanical wear can cause nylon monofilament to fragment into microparticles, particularly if line is lost in water or discarded improperly. This poses environmental rather than direct consumer toxicant risk, but proper disposal is prudent.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Skin irritation or abrasion
Nylon monofilament can cause mechanical abrasion or localized irritation if drawn tightly across skin or mucous membranes, but this is physical injury rather than chemical hazard and not specific to this brand.
Heavy metals
No reports of lead, cadmium, or other heavy metals in Berkley Trilene XT monofilament. Industry standard for fishing line does not include heavy-metal dyes or stabilizers that would pose leaching risk.
Source, FDA ↗Volatile organic compound off-gassing
Nylon monofilament does not off-gas formaldehyde, VOCs, or odorous compounds under normal storage or use conditions. Any odor from a new spool is residual manufacturing scent and dissipates without health concern.
Ingestion or aspiration hazard
This product is not intended for consumption and poses no toxicological ingestion risk if accidentally swallowed in small amounts, though mechanical obstruction is a theoretical risk (extremely rare in practice).
The full breakdown
What it's made of and why it matters
Berkley Trilene XT is extruded nylon monofilament, a synthetic polymer engineered for tensile strength and water resistance in fishing applications. Nylon monofilament does not contain added heavy metals, phthalates, or volatile organic compounds as part of its standard formulation. The material is thermally stable at normal handling temperatures and does not off-gas or leach into aquatic environments in ways that pose consumer health risk during typical use as fishing line.
The brand's record and disclosure
Berkley (owned by Pure Fishing, a Newell subsidiary) is a major fishing-tackle manufacturer with decades of market presence and no established history of product safety recalls or toxicant contamination in monofilament lines. The brand does not publicly disclose detailed chemical composition or third-party safety certifications for fishing line products, which is typical for the category. No regulatory actions or safety controversies specific to Trilene XT monofilament are on record.
How it compares in its category
Nylon monofilament lines (Berkley, Spiderwire, Stren, and private-label variants) occupy the mainstream of recreational fishing and all share the same basic material chemistry and safety profile. Fluorocarbon alternatives exist but introduce similar or greater opacity concerns; braided lines use polyethylene. Trilene XT sits at the mid-range price point with no material safety distinction from competitors in the monofilament segment.
If you buy it
Store spools indoors, away from direct sunlight, to preserve tensile properties and prevent UV-induced brittleness. Do not heat or incinerate the line; dispose of spent monofilament as solid waste (do not flush, as it risks entanglement of aquatic life). Replace the line annually or after heavy use, as nylon degrades over time and weakened line poses functional failure risk rather than health hazard. Wash hands after handling if skin sensitivity exists, though nylon contact dermatitis is rare.
