Problems solved by technology

[0002] Corrugated paper is a plate made of liner paper and corrugated corrugated paper bonded by adhesive. It may be wet by rain or sea water during use, which will affect its use.
However, the existing adhesives for corrugated paper have the problems of poor moisture-proof ability and slow drying speed. The corrugated paper bonded with it does not have the effect of waterproof and moisture-proof, cannot protect the packaged goods well, and the product quality cannot be guaranteed.
