For goods with long, tall shapes and narrow widths, long cardboard box for shipping are the optimal choice.

Understanding an important of the right shipping packaging plays a key role in the goods transportation process, Khang Thanh introduces you to the points to keep in mind to produce satisfactory long shipping boxes.

1. Determine the size and weight of the goods

To produce long cardboard boxes that suit your needs, there are two criteria to avoid waste and maximize the product protection ability of the shipping box: size and weight of the goods.


Firstly, you need to measure the size of the items to be transported accurately. Measure the object’s length, width and height, then increase the shipping box size by 2-3cm to insert paper splints, shaped trays or bubble wrap to protect the product.

Besides cardboard boxes with typical lengths, you need to accurately measure the size of the goods to adjust and customize the long box for shipping.

On the other hand, measuring the weight of products is an essential part of deciding the thickness of corrugated materials used for shipping boxes. The long packaging boxes must have standard rigidity to maximize the protective function.

5. Benefits of producing long shipping box

Ability to protect goods

Long and thin items will be more suitable for long cartons than regular square or rectangular cartons.

Thanks to its narrow width and high length, this shipping box structure will fit objects tightly, reducing vibration and impact and providing maximum protection for goods during transportation.

Cost-effective shipping packaging

Compared to size, although this type of carton has an outstanding length, the width is very narrow to suit specific goods. Therefore, compared to the spread size, long cartons will be smaller, significantly reducing costs.
