瓦楞纸箱是用瓦楞纸板经过模切、印刷、压痕、钉箱(或粘箱)制成的一种硬度大的纸质包装。
Corrugated box is a kind of hard paper packaging made of corrugated board through die cutting, printing, indentation and nailing (or gluing).
瓦楞纸箱以其独特的硬度逐渐取代了过去的木箱包装，销量位于包装制品之首。
Corrugated box with its unique hardness gradually replaced the past wooden box packaging, sales in the first packaging products.
大家知道，纸箱除了能保护商品外，还要能体现商品的信息，便于商品的识别存储等，这就需要对纸箱进行印刷。
As we all know, cartons can not only protect the goods, but also reflect the information of the goods and facilitate the identification and storage of the goods, which requires the printing of cartons.
现在主要有两种纸箱印刷方式和生产方式：凸版印刷(也叫纸箱水墨印刷)和平版胶印(也叫油墨彩色印刷)。
Now there are mainly two carton printing methods and production methods: relief printing (also known as carton ink printing) and offset printing (also known as ink color printing).
瓦楞板作为纸箱的主体，常用的有A、B、C、E、F楞，厚度依次减少，A楞更厚，F楞更薄。
Corrugated board as the main body of the carton, commonly used a, B, C, e, F, the thickness decreases in turn, a is the thickest, f is the thinnest.
一般同样材质的瓦楞纸，厚度与挺度是成反比的。
Generally, the thickness and stiffness of corrugated paper of the same material are inversely proportional.
现在生产瓦楞纸箱的工艺流程，因纸箱设计的特点，规格尺寸等，主要分有三种：
At present, the technological process of producing corrugated boxes is mainly divided into three types due to the characteristics of box design, specifications and dimensions
1、瓦楞纸板→印刷→开槽→模切→粘箱→包装全自动一次成型;
1. Corrugated board → printing → slotting → die cutting → gluing box → automatic one-time packaging;
2、瓦楞纸板→印刷→开槽→钉箱→粘箱或直接包装送货;
2. Corrugated board → printing → slotting → nailing → gluing or direct packaging and delivery;
3、瓦楞纸板→印刷→模切→钉箱→粘箱或直接包装送货。
3. Corrugated board → printing → die cutting → nailing → gluing or direct packaging delivery.
设计瓦楞纸箱，一般要考虑三个尺寸：内尺寸、外尺寸和制造尺寸。
Generally, three dimensions should be considered in designing corrugated box: internal dimension, external dimension and manufacturing dimension.
一般，外尺寸=内尺寸 *2*纸板厚度(考虑实际制造过程的厚度损失);制造尺寸=外尺寸-系数(系数一般取决于纸板的层数与材质)。现实中还应根据不同客户的特点合理调整上下偏差。
Generally, the outer size = inner size * 2 * paperboard thickness (considering the thickness loss in the actual manufacturing process); Manufacturing size = external size - coefficient (coefficient generally depends on the number of layers and material of paperboard). In reality, we should adjust the up and down deviation reasonably according to the characteristics of different customers.
