Abstract

An improved continuous process for manufacturing thermoplastic synthetic resin corrugated board sheets, which comprises continuously advancing a continuous sheet of thermoplastic synthetic resin through a core sheet forming zone thereby forming the moving sheet. on a corrugated cardboard core sheet, and continuously bonding by surface-melting pressure surface coatings of a continuous thermoplastic synthetic resin sheet, coincidentally or successively, on the front and rear faces of said shaped core sheet, characterized in that thin layers of a thermoplastic synthetic resin (B) having a melting point at least 10ºC lower than that of any thermoplastic synthetic resin (A) constituting said core sheet, and surface coating sheets are formed on faces chosen from the group which Consists of (i) front and back faces of thermoplastic synthetic resin sheet ca to be formed inside the core sheet, (ii) faces to be attached to the core sheet, of each one of said surface coatings, and (iii) all the faces mentioned in (i) and (ii), before shaping the core sheet and before melt pressure bonding of said surface coatings onto said continuous core sheet.
