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+.

What are the advantages of Corrugated Plastic Sheets?
1. Moisture-proof, waterproof, corrosion-resistant, salt-alkali resistant.
2. There are many kinds of corrugated plastic correx sheets. Anti-static correx sheets can be produced by adding anti-static agent to the raw material, flame-retardant hollow board can be produced by adding flame retardant to the raw material, and conductive agent can be added to the raw material to produce Conductive coroplast sheets.
3. The coroplast has stable chemical properties, is non-toxic, tasteless and harmless, and is environmentally friendly.
4. The sheet material of the coroplast is extremely processable, and it can be used for painting, filming and other processes.
Our factory covers an area of more than 15,000 square meters. Now we have11 advanced production lines with full sets of auxiliary machines running 2 shifts every day.
