1. Type a ridge

A型楞的特點(diǎn)是單位長(zhǎng)度內(nèi)的瓦楞數(shù)量少，而瓦楞高。使用A型楞制成的瓦楞紙箱，適合包裝較輕的物品，有較大的緩沖力。

The characteristic of type a corrugated is that the number of corrugated in unit length is small, while the corrugated height is high. The corrugated box made of A-type corrugated is suitable for packing lighter articles and has large cushioning force.

2、B型楞

2. Type b ridge

B型楞與A型楞正好相反，單位長(zhǎng)度內(nèi)的瓦楞數(shù)量多而瓦楞，其性能也與A型楞相反，使用B型楞制成的瓦楞紙箱，適合包裝較重和較硬的物品，多用于罐頭和瓶裝物品等的包裝。另外，還有一種傾向就是利用B型楞堅(jiān)硬不易破的特點(diǎn)，經(jīng)過(guò)沖切后制成形狀復(fù)雜的組合箱。

B-type corrugated box is just opposite to A-type corrugated box. The number of corrugated boxes per unit length is large and the corrugated is the lowest. Its performance is also opposite to that of A-type corrugated box. The corrugated box made of B-type corrugated box is suitable for packing heavy and hard articles, and is mostly used for the packaging of canned and bottled articles. In addition, there is a tendency to make use of the hard and difficult to break characteristics of the B-shaped ridge to make a composite box with complex shape after punching and cutting.

3、C型楞

3. C-shaped ridge

C型楞的單位長(zhǎng)度的瓦楞數(shù)及楞高介于A型楞和B型楞之間。性能則接近于A型楞。近年來(lái)隨著保管、運(yùn)輸費(fèi)用的上漲，體積較小的C型楞受到人們的重視，現(xiàn)已成為歐美采用的楞型。

The corrugation number and height per unit length of C-type corrugation are between A-type corrugation and B-type corrugation. The performance is close to that of A-type ridge. In recent years, with the rise of storage and transportation costs, the smaller C-shaped corrugated has attracted people's attention and has become the corrugated used in European and American countries.

其次，談一下用于內(nèi)包裝和小包裝的E型瓦楞的特點(diǎn)。

Secondly, talk about the characteristics of e-type corrugated for inner packaging and small packaging.

4、E型楞

4. E-shaped ridge

E型楞在30㎝長(zhǎng)度內(nèi)的楞數(shù)一般為95個(gè)左右，楞高約為1.1㎜(我公司E瓦楞高為1.7㎜)與外包裝用的A、B、C型瓦楞相比，具有更薄更堅(jiān)硬的特點(diǎn)。因此，開發(fā)E型楞主要目的是將它作成折疊紙盒以增加緩沖性。用E型楞制成的瓦楞紙盒，外觀美觀、表面光滑，可進(jìn)行較復(fù)雜的印刷，因此通常用于裝潢性瓦楞紙盒。

The number of e-type corrugated within 30cm is generally about 95, and the corrugated height is about 1.1mm (the e-corrugated height of our company is 1.7mm). Compared with type A, B and C corrugated used for outer packaging, it is thinner and harder. Therefore, the main purpose of developing E-shaped corrugated is to make it into a folding carton to increase the cushioning. Corrugated cartons made of e-type corrugated have beautiful appearance and smooth surface, and can be used for more complex printing. Therefore, they are usually used for decorative corrugated cartons.
