Abstract

Corrugated sheet is made by bonding a flexible sheet material by a series of parallel welds to a 2nd sheet which can subsequently be heat shrunk to draw the welds closer together. Continuous sheet is formed into longitudinal corrugations and subsequently laminated between facing sheets to make stiff board, esp. if then laminated with continuous sheet having transverse corrugations to make perpendicularly double corrugated packaging board. Pref. corrugated laminates have flexible non-shrink layer of e.g. paper, ono-oriented plastic film, fabric or metal (Al) foil, and the heat shrinkable layer of PVC or polyethylene film, esp. 0.05 mm thick with a potential contraction of >=20%. Process allows continuous prodn. of longitudinal or crossed axis corrugated core board, thus increasing output rates and reducing cost. Presence of thermoplastic layer improves moisture barrier props. of the board.
