U.S. developed M-Guard screen wet cardboard

Libery/Mining Paper Co., Ltd. of Minnesota, USA, has developed M-Guard screen wet cardboard, which resembles corrugated paperboard. It is also similar to the commonly used inner liner, which is printable, recyclable, and regrind. The board's screen wet performance has a visual effect. This screen wet performance is due to the effect of internal chemical bonding during the manufacturing process of the paperboard, saving time without any conversion. The board achieves good screen wet performance through its inherent absorption.
