Several types of paper are used in the corrugated board industry. They are divided in 2 different types called Liner (箱板紙）and Fluting/Medium(瓦楞芯紙）./ 有幾種類型的紙用于瓦楞紙板行業(yè)，它們可分為兩種類型：箱板紙和瓦楞芯紙。

Liner paper is mainly used as the outside papers of the corrugated sheet. We use a top-liner(里紙）on the single-facer and a bottom-liner(面紙）at the double facer. There are also a middle-liner(中紙）when running double-double, but in some cases, fluting or medium is also used as middle-liner./箱板紙主要用在瓦楞紙板的外面。 單面機(jī)部分的叫里紙，雙面機(jī)部分的叫面紙。當(dāng)生產(chǎn)多瓦楞紙板時又要用到中紙，在某些情況下，瓦楞原紙也被用來做為中紙使用。

Liner paper differs from fluting or medium paper, mainly through the different fibre length, and throught the fabrication methods, it is also mostly more expensive./箱板紙與瓦楞芯紙的主要不同之處在于纖維的長度和制造方法，箱板紙更昂貴。

Different types of liner are used on the corrugator. such as: KRAFTPAPER(牛皮紙）， SCHRENZ or WASTEPAPER(廢紙原紙）， DUPLEX or TEST LINER(全廢箱板紙）

Different types of fluting: SCHRENZ or WASTEPAPER(廢紙原紙）， SEMI-CHIMICL(半化學(xué)紙）， a combination of both(兩者混合）, and STRAW or BOGUS PAPER(草紙）.

All of these papers are available in different grades and quality's, one more easy to run on the corrugator than others, depending on different factors. we call this the "runnability" of the paper. Especially the fluting plays a big part in the running of the corrugator. We will look further into the different demands whick will decide what makes a certain paer easy to run, and another difficult./ 所有原紙都有不同的檔次和質(zhì)量，一種原紙比另一種原紙更容易在瓦楞機(jī)上運(yùn)行，取決于不同的因素。我們將之稱為原紙的“運(yùn)行性能”。尤其是瓦楞芯紙對瓦楞機(jī)的運(yùn)行有著重大的影響。我們將深入了解為什么有的原紙容易運(yùn)行，而有的不容易運(yùn)行。

SCHRENZ or WASTEPAPER: 廢紙原紙
has been widely used in most of the Eurpean country, especially in Holland, Germany, Belgium, Austria, France. This maily due to the fact that these countrys have practically no virgin wood to be used for the paper industry, as Scandinavia has. it is a porous paper, who takes up liquid easily such as starch, but is rather weak as a paper. Is therefore mainly used as fluting paper, due to the fact that it can become a rather stiff paper. Because it is cheap, it is also widely used as an inside liner. 曾在歐洲國家被廣泛使用，尤其是荷蘭，德國，比利時，奧地利和法國。主要原因是這些國家缺乏如北歐那樣豐富的原木資源。它是一種多孔的紙，易吸水，例如淀粉漿，強(qiáng)度比較差，可變得較堅挺，因此，主要用作瓦楞芯紙。 因為它價格便宜，所以也被廣泛用作中紙。

When used as a fluting, remember that schrenz is rather difficult to take-up heat, therefore it is essential that we heat the paper sufficiently to reach the correct temperature. Use the pre-conditioner to achieve this.當(dāng)我們使用廢紙原紙作為瓦楞芯紙使用時，一定要注意，它的吸熱性非常差，因此，要達(dá)到我們所需要的溫度，充分的加熱是必不可少的，我們可通過預(yù)熱烘缸來幫助我們實(shí)現(xiàn)。

SEMI-CHEMICAL.半化學(xué)紙：
The name semi-chemical is mostly used to indicate cellulose and less for paper, as it is nearly always used to mix with wastepaper or old paper. This paper has been developed especially for the corrugted board industry, and has the advantage to creat a very stiff, strong fluting.半化學(xué)主要用來指紙的纖維素低，因為它幾乎總是用來混合廢紙或舊紙制成。此類紙?zhí)貏e適合于瓦楞紙板行業(yè)，具有成型后堅挺的優(yōu)勢。

Some scandinavian papers have also a small percentage of Kraft fibre mixed in it, what increase even more the strength of the fluting, but also makes it more difficult to run! The fibres are very short and hard, are mainly positioned in length direction and causes therefore a rather difficult fluting to run. It is nearly impossible to run semi-chemical without the steam showers and without conditioning the paper with the pre-conditioner.一些北歐的原紙混合入了一小部分?？ɡw維用來進(jìn)一步加強(qiáng)瓦楞芯紙的強(qiáng)度，但也使得它更加難以運(yùn)行！纖維很短和硬，主要依長度方向分布，因此運(yùn)行起來相當(dāng)困難。沒有蒸汽噴淋和用預(yù)熱器預(yù)熱的幫助，半化學(xué)紙是非常難以運(yùn)行的。
