What Is a Fishing Line Made Of?

Fishing line is an important tool for anglers, whether they’re fishing in freshwater or saltwater. It is the main connection between the fish and the angler, and it is vital that it be strong, durable, and able to withstand even the harshest of conditions. But what exactly is a fishing line made of?

Fishing lines come in many varieties, but all of them are composed of some form of polyethylene. This type of plastic is strong, durable and resistant to UV rays, so it can withstand long days out on the water without breaking or fraying. Polyethylene also has low stretch properties, making it ideal for casting and retrieving lures with precision.

Fluorocarbon fishing line is a popular choice for anglers because it is virtually invisible underwater. This type of fishing line is made from fluoropolymers that have been extruded into lines with different diameters and strengths. Fluorocarbon fishing lines are also incredibly abrasion-resistant, so they won’t break easily when dragged over rocks or other rough surfaces.

Braided fishing lines are made from strands of high-strength fibers such as Spectra or Dyneema that have been woven together to create a single continuous line. Braided lines are extremely strong and offer excellent sensitivity with minimal stretch – making them perfect for detecting even the slightest nibbles from fish. They also come in a variety of colors so you can choose one that best matches your fishing conditions.


Fishing lines come in a variety of materials including polyethylene, fluorocarbon and braided fibers such as Spectra or Dyneema. Each material has its own advantages and disadvantages depending on the conditions you’re fishing in. No matter which material you choose though, make sure you select one that will stand up to your needs so you can enjoy your time on the water.
