旧瓦楞箱的回收量及消耗量正迅速增长(见表1)。消耗量变化主要体现在牛皮挂面纸板和半化学浆瓦楞芯层中旧瓦楞箱(OCC)的利用量增加。目前,牛皮挂面纸板中约10%、半化学浆芯层约30%的配料为OCC。

Changes in consumption are mainly reflected in the increased use of old corrugated containers (OCC) in kraft linerboard and semi-chemical pulp corrugated core. At present, about 10% of the veneer of veneer and about 30% of the semi-chemical core layer is OCC.
