Custom Corona Treated Waterproof Heavy Duty 4x8 Coroplast Sheets
Coroplast sheet is an eco-friendly plastic sheet made of
polypropylene material. It is also known as
correx/corflute/coroplast/danpla/cartonplast sheets. It has the
properties of waterproof, heavy-duty, non-toxic, recyclable,
cost-effective, strong and durable, and so on.
Now I will introduce you a special type of coroplast sheet, it is a
corona-treated coroplast sheet.
The corona-treated coroplast sheet is an ordinary coroplast
sheet with corona treatment. Corona treatment is a kind of electric
shock treatment, which makes the surface of the board 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 are destroyed 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+.
