Plastic filament facts…
Many store labels don’t tell you what the plastic filament(s) are.
They should—because there can be large differences in performance and cost
per year of life.
Why don’t they? Some don’t know. Others don’t care—and assume that users
buy on price alone.
That’s why we advise not buying rope, twine or tape from manufacturers/
sellers who do not clearly state which filament it is.

Filament options…
In descending order of cost per ft and inherent resistance to sunlight:
1. Polyester.
2. Virgin polyethylene monofilament.
3. Polyethylene monofilament.
4. Polypropylene film.
The differences between these in response to sunlight, movement, stretching,
mildew and years of life can be large. Some work for less than 2 years—and some
for more than 20 years.
Relative visibility to animals and
humans differs. And it’s critical. Why?
1. If it’s easy to see, it’s more likely to
stop livestock and wildlife.
2. Visibility = avoidance = safety for both
animals and humans.
But animals and humans differ in the
ability to see fences. Many animals see color
poorly. Their world is largely black, white
and shades of gray. But most have better
night vision than we do. (And birds see
much better than humans.)
Photos (above) simulate both direct
sunlight and “nightlight.” To achieve this
we eliminated the color from the photo and
enhanced the amount of night light.
Key conclusions:
• Size in diameter or width matters—
larger is always better for visibility.
• Contrast matters—black/white is
much more visible than solid white,
green, orange or black.
