    4×8 corrugated plastic signs are hollow structural advertising boards made of polypropylene (PP) material with dimensions of 4ft x 8ft. This kind of advertising board is very popular and is often used as road signs, hazard warnings, election boards, promotion boards, menu catalogs, event displays, etc.

    Corrugated plastic signs are also called coroplast signs, correx signs, corflute signs, coro signs, etc.

    When customers need high-quality corrugated plastic signs, we recommend corona-treated coroplast sheets. Corona treatment is a kind of electric shock treatment, which makes the surface of the sheet have higher adhesion. The principle is to use high-frequency and high-voltage corona discharge on the surface of the hollow board (high-frequency AC voltage is as high as 5000-15000 V/㎡) to generate low-temperature plasma. These ions are penetrated by the electric shock to the surface of the board and destroy Its molecular structure, and then the surface molecules being treated are oxidized and polarized, and the ion shock corrodes the surface, so as to increase the adhesion ability of the pp hollow board surface. We are a professional coroplast sheets manufacturer in China and the dyne value of our coroplast sheets can reach 60+.
