According to the different strength of corrugated board, different layers can be made. All kinds of corrugated board are classified by the number of layers, including double-layer, three-layer, five-layer and seven-layer paper, any combination of different types of corrugated board, and there must be at least one concave convex core paper sandwich layer in the middle of the corrugated board.

按照断面楞型，可以分为U型，V型，UV型。它们都有着各自的特点；

According to the cross-section corrugated type, it can be divided into U-shaped, V-shaped and uv-shaped. They all have their own characteristics;

V型强度高，但弹性差不容易恢复。

The strength of V-shape is high, but the elasticity is poor and it is not easy to recover.

U型弹性好容易恢复，但是强度不高。

The U-shaped elasticity is good and easy to recover, but the strength is not high.

UV型强度高，而弹性好容易恢复。

UV type has high strength, good elasticity and easy recovery.

所以目前市场上使用多的就是这种UV型瓦楞纸板。

So at present, the most used in the market is this type of UV corrugated board.

瓦楞纸箱的制造过程

Manufacturing process of corrugated box

原纸

Base paper

瓦楞纸板的原材料是需要达到纸箱等级的纸张，一般瓦楞纸芯主要是由较长的原木纤维制成的，而上下两层纸板则是由较短的硬木纤维制成。

The raw material of corrugated board is the paper that needs to reach the carton grade. Generally, the corrugated core is made of long log fiber, while the upper and lower layers of cardboard are made of shorter hardwood fiber.

还会利用各种回收的废纸，将其经过筛选，打碎制成纸浆以及干燥等工序后，制成大卷的纸张。

It will also use all kinds of recycled waste paper, after screening, crushing into pulp and drying process, to make large rolls of paper.

压制纸板

Pressboard

就是压制瓦楞纸芯，通过机器将纸张从大卷上拉出，进入到一组高温高湿并带齿轮的瓦楞辊中，在两个齿轮辊的压力下让纸张形成凹凸相间的瓦楞形状，使瓦楞纸板具有强度和缓冲能力。

The first is to press the corrugated paper core. The paper is pulled out from the large roll by the machine and enters into a group of corrugated rollers with high temperature and humidity and gears. Under the pressure of two gear rollers, the corrugated paper forms a corrugated shape with concave and convex phases, so that the corrugated board has strength and buffering capacity.

成型的瓦楞纸芯会碰到另一个带胶水的辊轮，就会将瓦楞纸芯一面粘上胶水，在转动过程中正好粘在，从另一辊轮上引出的卷纸上。

The formed corrugated paper core will touch another roller with glue, and glue will be stuck on one side of the corrugated paper core, which will stick to the roll paper from the other roller during the rotation.

还有在瓦楞纸板的另一面粘上卷纸，通过高温让胶水干燥后，就会形成双层瓦楞纸板。

Also in the other side of the corrugated paper, through high temperature to dry the glue, it will form a double-layer corrugated board.
