一是被包物品的特性、實物形狀、內裝物品，在確定紙箱內尺寸的伸放時應考慮不同，楞型構成的瓦楞紙板對伸放的影響。如對硬度大的內裝物，惠州紙箱廠在確定紙箱內尺寸的伸放時不能小，可約為取上公差，以防被包物品裝不進去。而內裝物是柔軟的物品，在確定紙箱內尺寸時就盡量取下公差數，因為這類物品在倉儲過程中會隨倉儲時間的延長，物品受重力作用而下沉，引起紙箱高度空間變大，導致抗壓能力下降。

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.

二是要考慮紙箱在包裝產品過程中的要求。如重型紙箱廠家是用機械包裝產品，還是工人用手工包裝產品，工人在包裝產品時操作是否方便，是否還需要使用其他工具才能包裝，有無其他特殊要求等。這些因素在設計紙箱時也應考慮進來。

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.

三是被包物品的運輸方式。在確定是用紙箱內徑還是外徑時，除要考慮被包物品的特性外，還要考慮到運輸條件，如汽車、火車、集裝箱、托盤對紙箱尺寸的要求，這些是確定紙箱尺寸要考慮的因素。另外倉儲條件和儲存時間、紙箱的物理強度要求也是設必領要考慮的因素。

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.

四是惠州紙箱廠的瓦楞紙箱加工工藝與生產能力。從紙箱的瓦楞形狀、用材選擇到紙箱的加工工藝方案及流程和設備的加工能力、印刷內容與印刷方式、印刷版的選用，并要根據惠州紙箱廠設備的加工精度考慮紙板、紙箱的伸放，分紙毛邊。另外就是紙箱搖蓋的壓痕寬度和不同的楞型與不同楞型組合的瓦楞紙板尺寸伸放選擇，以及各生產環節的流轉銜接要求。

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.
