What should I pay attention to when using a corona treated PP corrugated sheet?

The corona-treated sheet has a strong adsorption force for dust. We recommend that the PP corrugated sheet used for printing should be wrapped by PE film and stored in a clean, dust-free warehouse.

Try not to paste a temporarily used sticker on the corona-treated PP corrugated sheets because it has a strong adsorption to the glue. The glue will penetrate into the surface of the sheet and is difficult to remove.

After six months, the corona effect will diminish. Therefore, it is recommended to print and use polypropylene corrugated board within half a year to ensure the best results.
