Corrugated Plastic Vs. High Denisty Polyethylene
The majority of the plastic signs that we produce are made of high-density polyethylene plastic. It is a solid plastic that is very flexible and will not crack when it is bent even if it is very cold out. This type of plastic sign is made to give you more longevity. Screen printed plastic signs will last roughly 7-10 years. This number only refers to fading. Typically the sign will begin to fade long before the material actually wears down.
Corrugated plastic is hollow and has flutes running through it. Typically this is the type of material that yard signs (political signs) are made out of. Corrugated plastic is more appropriate for short-term outdoor use. In addition, the flutes that run through the sign allow for easy installation of stakes for easy mounting in a yard.
