  • Apparatus and method for producing waterproof structural corrugated paperboard
    Patent number: 8631848
    Abstract: Two paper webs saturated with an A-phase phenolic resins and dried to a B-phase are conveyed through separate low melting point metal alloy baths, one web after being corrugated, to convert the resin to a fully cured C-phase, whereafter the webs are joined to form a waterproof single face corrugated web.
    Type: Grant
