Method for producing reinforced corrugated paper board with two interlocking corrugations and with outer cladding

摘要

A method for producing reinforced corrugated board with enhanced resistance to curling uses a well-in-well process with two similar corrugated paper layers interlocked and linked by adhesive spots or strips (5, 6). The board is further strengthened by applying flat outer paper layers to one or both sides and securing same with adhesive spots or strips (4, 7).
