Ordinary corrugated boxes have poor water and moisture resistance. Today's waterproof and moisture-proof corrugated cartons, such as waxed cartons and polyethylene laminated cartons, cannot be recycled. Therefore, Japan has developed a new type of recyclable waterproof carton. This kind of carton contains hydrolyzable resin, has good moisture resistance, and can be degraded for recycling. It is a good substitute for waxed carton and laminated carton.
