1) Keep the pp corrugated sheet clean
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.
Check the following PP corrugated board wrapped by PE film.
2) Try not to paste a sticker on corona-treated panels
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.
3) The best service life of corona-treated panels is six months
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.
