Product Description

White coroplast signs :                                                                       

White coroplast sign is an extruded coroplast sheet(also called pp hollow board) with hollow structure, the raw material is environmentally friendly polypropylene, and the white coroplast sign has the characteristics of lightweight, non-toxic, corrosion resistance, non-polluting, waterproof, shockproof, anti-aging, etc.
When white coroplast sheets are used for signboards if c
ustomers have high requirements, the white coroplast sheets need to be corona treated. Corona treatment is a kind of electric shock treatment, which makes the surface of the pp hollow boards have stronger adhesion. The principle is to use high frequency and high voltage to discharge corona on the surface of the plate to be processed (high-frequency AC voltage is as high as 5000-15000V/㎡)

The thickness of the pp hollow board can be 2-12mm, but the plastic hollow board used for the advertising board is usually 4mm-6mm, the most used is 4mm, and the weight of the 4mm coroplast sign board is 600g-1200g
