摘　　要：我国造纸原生纤维资源短缺,2017年国产原生纸浆仅占纸浆消耗总量的16.4%;废纸作为一种再生资源,成为制浆造纸不可或缺的主要原料之一,对森林资源保护起到不可替代的作用。国内包装纸板基本上都采用废纸生产,由于国内废纸循环次数较多,纤维损耗大,物理强度差,需要长纤维的补充。进口废纸中的原生木浆纤维含量高、强度好,是一种好的再生资源,对我国包装纸板生产具有重要作用。大量减少进口废纸容易造成纸浆中长纤维不足,会影响大型低定量高速纸机的抄造率(断纸、降低车速)和产品质量。Due to China＇s shortage of original fiber resources, domestic original pulp output only accounted for 16.4% of China＇s total pulp consumption in 2017. So the waste paper, as a kind of recycle materials, becomes the important raw material for pulp and paper industry, and plays a vital role in forest resources protection. China domestic packaging board is mainly made from waste paper, and it needs a supplement of imported long fiber because China domestic waste paper is featured by easy fiber loss and poor physical performance during recycling. Comparably, imported waste paper has the advantages of high original fiber content and good fiber strength, which makes it the better regenerated material for packaging board manufacture. Thus, reducing the importation of waste paper to a large extent can possibly lead to inadequate long fiber supplement, and influence the formation rate of paper sheet and the quality of paper products.
