What Daiwa J-Braid Grand X8 Line is made of, ingredients and materials
Daiwa J-Braid Grand X8 is a braided polyethylene (PE) fishing line with a water-resistant coating applied to the fiber bundle. Polyethylene itself is chemically inert and does not leach into aquatic or food environments under normal fishing use. The coating, however, is the unknown variable, water-resistant treatments on fishing lines historically use Teflon-family coating or other synthetic compounds to reduce water absorption and increase durability, and some formulations may contain PFAS-based repellents. Daiwa has not publicly disclosed the specific coating chemistry for this product line.
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.
Microplastic shedding from coating degradation
As the water-resistant coating breaks down from UV exposure and mechanical wear, fine fibers and coating particles shed into waterways. This is a known issue with all braided PE lines but severity depends on coating durability and composition, which Daiwa has not disclosed.
PFAS
Water-resistant treatments on fishing line commonly employ Teflon-family coating historically used in PFAS chemistry, though modern alternatives exist. Daiwa's silence on this question leaves uncertainty; the 40/100 PFAS grade reflects this ambiguity.

PE itself is chemically stable, but braided line structure breaks apart into microfibers under UV and mechanical stress, creating persistent plastic pollution. Concentration risk is highest in catch-and-release fishing environments and freshwater systems with slow degradation.
Coating leachates under freshwater or saltwater immersion
While PE core does not leach, any coating additive (UV stabilizers, slip agents, or water-repellent compounds) may migrate into surrounding water over months of use, particularly in warm or brackish conditions. Daiwa has provided no migration or leachate testing data.
What’s reassuring
Heavy metals
J-Braid Grand X8 is available in multiple colors; no reports of heavy metal testing or contamination in dyes used on Daiwa lines. Standard commercial fishing line dyes are not routinely screened, so absence of reports does not confirm absence of risk.

The brand's record and disclosure
Daiwa (parent company Globeride Inc., Japan) maintains a limited public disclosure policy on material composition and chemical treatments. No independent third-party certifications (e.g., environmental or chemical safety standards) are publicly advertised for this line. No recalls or reported safety incidents specific to J-Braid Grand X8 are on record. The brand has not issued statements clarifying PFAS use or avoidance in fishing line coatings, a common gap in the recreational tackle industry.
How it compares in its category
Braided PE lines are the dominant choice in modern fishing tackle and generally pose fewer chemical hazards than monofilament nylon lines, which can leach additives. Most major manufacturers (Berkley, Shimano, KastKing) apply proprietary water-resistant coatings without public PFAS transparency, making J-Braid Grand X8 representative of category opacity rather than an outlier. Uncoated PE lines are theoretically available but rare and perform worse in real conditions. No fishing line category offers routine third-party chemical certification.
If you buy it
Store line away from prolonged direct sunlight to slow polymer degradation and coating breakdown, which can increase microfiber shedding over years of use. Rinse line in freshwater after saltwater exposure to reduce salt crystallization and coating stress. Replace line annually or after visible wear, fraying, or color fading, as these signal coating compromise. Do not assume PE braids are inert in aquatic environments once the coating degrades; microfiber fragments persist in freshwater and saltwater ecosystems.
