Palletizing cartons is now standard practice in export shipping. It prevents damage to paper boxes, facilitates forklift handling, and streamlines
management, thus simplifying the handling process and reducing transportation costs. The loaded pallets are typically secured together with
stretch film and strapping to prevent boxes from falling, being crushed, or getting lost during complex transportation processes. This also helps
prevent theft, simplifies inventory management, and optimizes warehouse space.
However, how to stack cardboard boxes is a very meticulous task. It’s not as simple as just putting the boxes on a pallet as commonly believed;
if you think that, you’re making a big mistake.
What Is The Purpose Of Using Pallets To Pack Paper Boxes?
Cardboard boxes are typically the first choice for storing and transporting goods. Packing cardboard boxes onto pallets for transport is currently
the most efficient way to store or transport large quantities of goods. It not only saves space and time but also saves labor and reduces handling
difficulties.
If you are a company that frequently ships goods or operates in international e-commerce, you may already be using palletized shipping. Even
if you have a regular carrier, you need to understand pallet placement techniques to prevent damage during transport.
Tips For Palletising Cardboard Boxes:
1. Ensure The Pallet Is Intact And Sturdy
Pallets serve as the base for all paper boxes, therefore the most important principle is that any base supporting an object must be sturdy.
Otherwise, even if the boxes are arranged well, they are prone to collapse during stacking or transportation.
Therefore, we need to ensure that the pallets are free of cracks, breaks, and any debris. Only when the pallets are intact can we use stretch film,
corner protectors, and straps for reinforcement, preventing the boxes from shifting, collapsing, or breaking during transport.
2. Make Sure Your Paper Boxes Are Stacked Well On The Pallet
Generally, it’s best to place the heaviest boxes at the bottom, as this lowers the center of gravity and makes them less likely to tip over. This also
increases the stability of the pallet and makes them more resistant to pressure, preventing damage to lighter items. However, stacking the heaviest
boxes together isn’t ideal either. The wisest approach is to distribute them evenly across the pallet. Even weight distribution contributes to structural
stability.
After placing the heaviest box at the bottom, do not stack the boxes in a pyramid shape, forming a triangle or an uneven distribution. Instead,
stack them into a cube composed of multiple boxes that are interleaved. If possible, rotate each box so that each box overlaps with the boxes
below it.
It’s important to note that while we fully agree that cartons on pallets should be stacked, as the interlocking mechanism provides greater stability,
vertical stacking is preferable when your product is very light, soft, or fragile. This is because the carton’s compressive strength is maximized in
this stacking method. However, very light products should not be stacked too high, as they are prone to tipping over.
3. Prevent The Box From Slipping
In international logistics, palletized transport typically uses airplanes or ships. However, seas are rough, ships rock, and airplanes inevitably
experience turbulence and tilting during flight. If boxes on pallets are not secured or fastened during these processes, they are prone to slipping
or shifting. This can result in minor issues like displacement and collisions, or more serious damage and breakage.
Fortunately, there are many ways to prevent boxes from slipping off pallets. For example, stretch film, high-strength straps, or even airbags can
be used. Stretch film should be wrapped around the boxes on the pallet at least four times, including the bottom of the pallet. If straps are used,
they need to be applied both horizontally and vertically.
4. Never Leave Overhangs
Regardless of the stacking method used, ensure that no cardboard boxes are suspended above the pallet edge. Do not overlap. Even the
slightest gap or misalignment will reduce the compressive strength of an individual box, decreasing its weight-bearing capacity and potentially
causing deformation. Therefore, when stacking boxes, place them close to the pallet edge, but not beyond it. This ensures stack stability and
facilitates securing.
Placing products in a suspended position not only easily damages them but also affects the measured area of the pallet, leading to errors in
the final shipping cost.
5. Paste Label
Labeling is crucial in both international and international shipping. It facilitates identification of goods by the pick-up person and warehouse,
and helps the recipient count and confirm the shipment. It also prevents goods from being lost or unidentified. Labels need to be affixed to
each box of goods. This is naturally a critical step in palletized shipping.
在出口运输中，将纸箱码放在托盘上（即托盘化）现已成为一种标准做法。这种做法不仅能防止纸箱受损，便于叉车搬运，
还能简化管理流程，从而降低搬运难度并削减运输成本。码放完毕的托盘通常会用缠绕膜和打包带进行固定，以防止纸箱在
复杂的运输过程中发生滑落、挤压变形或丢失的情况。此外，托盘化还有助于防范盗窃，简化库存管理，并优化仓库空间的
利用效率。
然而，如何码放纸箱却是一项非常讲究细节的任务。这绝非像人们通常以为的那样——仅仅把箱子随意堆放到托盘上那么简单；
如果您抱有这种想法，那就大错特错了。
**为何要使用托盘来码放纸箱？**
纸箱通常是存储和运输货物的首选包装容器。将纸箱码放到托盘上进行运输，是目前存储或运输大批量货物时效率最高的方式。
它不仅能节省空间和时间，还能节省人力，并降低搬运操作的难度。
如果您是一家频繁发货的企业，或者从事国际电子商务业务，您很可能已经在采用托盘化运输的方式了。即便您拥有长期合作
的承运商，您依然需要掌握正确的托盘码放技巧，以确保货物在运输过程中免受损坏。
**纸箱托盘化码放的实用技巧：**
**1. 确保托盘完好且坚固**
托盘是承载所有纸箱的基础，因此最核心的原则是：任何用于支撑物体的基底都必须坚固可靠。否则，即便箱子码放得再整齐，
在堆叠或运输过程中也极易发生坍塌事故。
因此，我们必须确保托盘上没有任何裂痕、破损或杂物。只有当托盘本身完好无损时，我们才能通过缠绕膜、护角板和打包带
进行加固，从而防止纸箱在运输途中发生移位、坍塌或破裂。
**2. 确保纸箱在托盘上码放稳固**
通常而言，最好将重量最重的纸箱码放在托盘的最底层，因为这样做能降低整体重心，从而减少倾覆的风险。这不仅能增强
托盘的整体稳定性，还能提升其抗压能力，从而有效保护上层较轻的货物免受挤压损坏。不过，将所有最重的纸箱集中堆放在
一起也并非理想之策；最明智的做法是将这些重箱均匀地分布在托盘的各个位置上。重量分布越均匀，整体结构的稳定性
也就越强。将最重的箱子置于底部后，切勿将箱子堆叠成金字塔形（即形成三角形或分布不均的形状）。相反，应将其堆叠成
由多个相互交错的箱子构成的立方体形状。如果条件允许，应调整每个箱子的朝向，使其与下方的箱子产生重叠。
值得注意的是，虽然我们完全赞同托盘上的纸箱应采用交错堆叠的方式（因为这种交错咬合的机制能提供更高的稳定性），
但若您的产品属于极轻、质地柔软或易碎类型，则更建议采用垂直堆叠的方式。这是因为在垂直堆叠法下，纸箱的抗压强度
能够得到最大程度的发挥。不过，对于极轻的产品，不宜堆叠得过高，以免因重心不稳而发生倾覆。
3. 防止箱体滑动
在国际物流中，托盘化运输通常通过航空或海运方式进行。然而，海况往往波涛汹涌，船体难免摇晃；飞机在飞行过程中
也无法避免遭遇气流颠簸或机身倾斜。若托盘上的箱子在这些运输环节中未得到妥善固定或捆扎，便极易发生滑动或位移。
由此可能引发轻微的后果（如位置错乱或相互碰撞），也可能导致更为严重的货物损坏甚至破裂。
幸运的是，目前已有多种行之有效的方法可以防止箱子从托盘上滑落。例如，可以使用缠绕膜、高强度捆扎带，甚至充气
气囊等辅助工具。若使用缠绕膜，应将其环绕托盘上的箱体至少四圈，且需将托盘底部一并包裹在内。若选用捆扎带，则
必须同时进行水平和垂直方向的捆扎。
4. 严禁箱体悬空
无论采用何种堆叠方式，都必须确保没有任何纸箱悬空于托盘边缘之外。切勿让箱体超出托盘边界。即使是极细微的缝隙
或错位，也会削弱单个纸箱的抗压强度，降低其承重能力，并可能导致箱体发生变形。因此，在堆叠箱子时，应将其紧贴
托盘边缘放置，但绝不可超出边缘范围。这样做既能确保堆叠结构的稳固性，也有利于后续的捆扎固定操作。
若将产品置于悬空状态，不仅极易导致货物受损，还会影响托盘实际占用面积的测量结果，进而引发最终运费核算上的误差。
5. 粘贴标签
无论是在国内物流还是国际物流中，粘贴标签都是至关重要的环节。标签不仅有助于揽货人员和仓库管理人员快速识别货物信息，
还能协助收货方进行货物的清点与核对；同时，它也是防止货物遗失或因信息不明而无法识别的有效手段。每箱货物均需贴附
标签。这自然是托盘化运输中的关键一步。
