纸箱是应用最广泛的包装制品，按用料不同，有瓦楞纸箱、单层纸板箱等，有各种规格和型号。
纸箱常用的有三层、五层，七层使用较少，各层分为里纸、瓦楞纸、芯纸、面纸，里、面纸有茶板纸、牛皮纸，芯纸用瓦楞纸，各种纸的颜色和手感都不一样，不同厂家生产的纸（颜色、手感）也不一样。
瓦楞纸板是由面纸、里纸、芯纸和加工成波形瓦楞的瓦楞纸通过粘合而成。根据商品包装的需求，瓦楞纸板可以加工成单面瓦楞纸板、三层瓦楞纸板、五层、七层、十一层等瓦楞纸板。
不同波纹形状的瓦楞，粘结成的瓦楞纸板的功能也有所不同。即使使用同样质量的面纸和里纸，由于楞形的差异，构成的瓦楞纸板的性能也有一定区别。国际上通用的瓦楞楞形分为四种，它们分别是A型楞、C型楞、B型楞和E型楞。它们的技术指标和要求见表一。A型楞制成的瓦楞纸板具有较好的缓冲性，富有一定的弹性，C型楞较A型楞次之。但挺度和抗冲击性优于A型楞；B型楞排列密度大，制成的瓦楞纸板表面平整，承压力高，适于印刷；E型楞由于薄而密，更呈现了它的刚强度。
Cartons are the most widely used packaging products. According to different materials, there are corrugated cartons, single-layer cartons, etc., with various specifications and models.
There are three or five layers commonly used in cartons, and seven layers are rarely used. Each layer is divided into lining paper, corrugated paper, core paper and face paper. Lining paper and face paper include tea board paper, kraft paper, and core paper use corrugated paper. The colors and hand feel of various papers are different, and the paper (color and hand feel) produced by different manufacturers are also different.
Corrugated board is made of face paper, lining paper, core paper and corrugated paper processed into corrugated wave by bonding. According to the demand of commodity packaging, corrugated board can be processed into single-sided corrugated board, three-layer corrugated board, five layer, seven layer and eleven layer corrugated board.
The corrugated board with different corrugated shapes has different functions. Even if the same quality of face paper and lining paper are used, due to the difference of corrugated shape, the performance of the corrugated board is also different. There are four types of corrugating shapes commonly used in the world. They are type A, type C, type B and type E. See Table 1 for their technical indicators and requirements. Corrugated board made of A-type corrugated board has good cushioning and certain elasticity, and C-type corrugated board is less than A-type corrugated board. But the stiffness and impact resistance are better than those of A-type ridge; The B-type corrugated board has a large arrangement density, and the corrugated board has a flat surface and high bearing pressure, which is suitable for printing; Because the E-shaped ridge is thin and dense, it shows its rigidity and strength.
