Monofilament fishing line

Monofilament is made by melting and mixing polymers and then extruding the mixture through tiny holes, forming strands of line, which is then spun into spools of various thicknesses.

Early monofilament did, however, have good knot strength and very low visibility to the fish, creating a small loyal following among fishermen.

It is often used for deep water fishing from boats because lower diameters are used, which give less resistance to currents, and the low stretch makes bites easily detectable.

PVDF is also a denser material and therefore not nearly as buoyant as nylon monofilament, and anglers often utilize fluorocarbon lines when they need lighter baits/lures to sink more quickly and stay deeper below the surface without using heavy sinkers.

Monofilament is not advisable for deepwater fishing, since it can absorb water, resulting in loose knots, and its sensitivity can decrease when it is wet.

[4] The transparency of monofilament fishing line makes it desirable for special effects where objects need to look like they are floating unsupported.

These lines are extremely difficult to spot when submerged in water, and fish, birds, and other marine life can easily become entangled, causing starvation, amputation, and death.

The breakdown of lines, especially in string trimmers, leads to microplastics which may cause starvation or poisoning of organisms in soil or water.
