一是被包物品的特性、实物形状、内装物品，在确定纸箱内尺寸的伸放时应考虑不同，楞型构成的瓦楞纸板对伸放的影响。如对硬度大的内装物，惠州纸箱厂在确定纸箱内尺寸的伸放时不能小，可约为取上公差，以防被包物品装不进去。而内装物是柔软的物品，在确定纸箱内尺寸时就尽量取下公差数，因为这类物品在仓储过程中会随仓储时间的延长，物品受重力作用而下沉，引起纸箱高度空间变大，导致抗压能力下降。
One is the characteristics of the wrapped goods, physical shape, the contents of the goods, in determining the size of the carton extension should be taken into account, the corrugated board formed by different corrugated board on the extension. For example, for the contents with high hardness, Huizhou carton factory should not be small in determining the size of the carton, and can be about the tolerance, so as to prevent the packed items from being packed. As the contents are soft goods, the tolerance number should be taken down as far as possible when determining the inner size of the carton, because this kind of goods will sink under the action of gravity with the extension of storage time in the storage process, resulting in the increase of the height space of the carton and the decrease of the compression resistance.
二是要考虑纸箱在包装产品过程中的要求。如重型纸箱厂家是用机械包装产品，还是工人用手工包装产品，工人在包装产品时操作是否方便，是否还需要使用其他工具才能包装，有无其他特殊要求等。这些因素在设计纸箱时也应考虑进来。
The second is to consider the requirements of cartons in the process of packaging products. For example, whether the heavy-duty carton manufacturers use mechanical packaging or manual packaging, whether the workers can operate conveniently when packaging products, whether they need to use other tools for packaging, and whether there are other special requirements. These factors should also be taken into account when designing cartons.
三是被包物品的运输方式。在确定是用纸箱内径还是外径时，除要考虑被包物品的特性外，还要考虑到运输条件，如汽车、火车、集装箱、托盘对纸箱尺寸的要求，这些是确定纸箱尺寸要考虑的因素。另外仓储条件和储存时间、纸箱的物理强度要求也是设必领要考虑的因素。
The third is the mode of transportation of the wrapped goods. When determining whether to use the inner diameter or outer diameter of the carton, we should not only consider the characteristics of the packed goods, but also consider the transportation conditions, such as the requirements of the size of the cartons by automobiles, trains, containers and pallets. These are the factors to be considered in determining the size of the cartons. In addition, storage conditions and storage time, physical strength requirements of cartons are also factors that must be taken into consideration when designing.
四是惠州纸箱厂的瓦楞纸箱加工工艺与生产能力。从纸箱的瓦楞形状、用材选择到纸箱的加工工艺方案及流程和设备的加工能力、印刷内容与印刷方式、印刷版的选用，并要根据惠州纸箱厂设备的加工精度考虑纸板、纸箱的伸放，分纸毛边。另外就是纸箱摇盖的压痕宽度和不同的楞型与不同楞型组合的瓦楞纸板尺寸伸放选择，以及各生产环节的流转衔接要求。
The fourth is the corrugated box processing technology and production capacity of Huizhou carton factory. From the corrugated shape and material selection of the carton to the processing technology scheme and process of the carton and the processing capacity of the equipment, the printing content and printing mode, and the selection of the printing plate, the extension of the paperboard and the carton and the separation of the rough edges should be considered according to the processing accuracy of the equipment in Huizhou carton factory. In addition, it is the indentation width of the box shake cover and the selection of the size of the corrugated board with different corrugated shapes and different combinations of the corrugated boards, as well as the requirements for the circulation and connection of each production link.
