Usually, the outdoor Corrugated Plastic Sign adopts 4mm thick white PP corrugated board. When it encounters extreme weather such as rain, the Corrugated Plastic Sign is too humid, and the temperature drops below zero, the Corrugated Plastic Sign should be designed with long service life. Generally, it can be dealt with by using PE material or increasing thickness and density.

If the area where the Corrugated Plastic Sign is located is very strong, it is best not to use bright colors such as red and orange as the substrate. Generally, darker colors are recommended for printing. You can also add anti-ultraviolet and anti-nutrition additives during the processing process, which can help extend the service life.
