종래, 건축 내, 외장용 또는 거푸집용, 간막이용, 문짝용 등의 판재로서 목재합판을 사용하였으나, 이 목재 합판은 내구성이 떨어지고 또한 습기에 취액하며 재생이 불가능한 단점이 있었다.Conventionally, wood plywood is used as a board material for building, exterior or formwork, partitioning, door door, etc., but this wood plywood has a disadvantage in that it is inferior in durability, insoluble in moisture, and impossible to regenerate.

이러한 문제를 해결하기 위하여, 열경화성 또는 열가소성 합성수지를 성형몰드에 의하여 단일체로 압출 성형하여 이루어진 판재를 사용하였으나, 이것은 합성수지 자체 비중이 목재보다 커서 취급과 사용에 어려움이 많았고 또한 하중강도가 떨어져 균형유지가 어려웠으며 제조원가도 높은 문제점이 있었다.In order to solve this problem, a plate made by extruding thermosetting or thermoplastic synthetic resin into a single body by a molding mold was used. However, since the synthetic resin itself has a specific gravity greater than that of wood, it is more difficult to handle and use, and also has a low load strength to maintain balance. It was difficult and there was a high manufacturing cost problem.

또한, 단순히 미발포 합성수지 시트를 다층으로 적층한 것, 또는 고무시트에 합성수지 필름을 여러층 적층한 것, 또는 합성수지 시트의 양면이나 일면에 금속박판을 적층한 것 등을 사용하였으나, 이것들은 휨변형의 문제는 어느정도 해결할 수 있었으나 자체 중량이 무거워 취급과 사용이 어렵고 또한 제조원가가 높은 문제점이 있었다.In addition, it was simply used to laminate a non-foamed synthetic resin sheet in a multi-layer, or to laminate a plurality of synthetic resin film on a rubber sheet, or to laminate a metal thin plate on both sides or one side of the synthetic resin sheet, but these The problem was solved to some extent, but its own weight was heavy, difficult to handle and use, and also had a high manufacturing cost.
