Container is an important means of transport for freight, but the packing box itself is not full, the actual utilization rate of container is low is the current situation of the transport industry.

The current container transportation situation: a 20-foot container, the volume is 33m3, generally loaded 25m3, the utilization rate is about 75%;

A 40-foot container, the volume is 67m3, the general load 55m3, the utilization rate is about 82%;

In view of the analysis of the current situation of low utilization rate of containers, we carry out technical research from the following aspects.

1, the establishment of a new idea for the design of container boxes is selected as a container as a means of transport, the carrying space has been determined, when the packaging of a certain kind of goods is determined, the volume of the box of goods should also be roughly determined. How to find the maximum load of the container? We believe that two conditions must be met:

First, the packing case should contain as much goods as possible. Second, the container should be filled with as many boxes as possible.

In order to achieve these two purposes, we have designed and manufactured our own and patented measuring tool - three-dimensional calipers. Three-dimensional calipers can create a relatively closed condition for the measurement of goods. The goods are all contained and squeezed to a certain extent, so that the true volume of the goods can be measured. Changing the stacking method of goods, you can measure a number of real volumes of different shapes, plus the relevant packaging thickness can get different volume of boxes, respectively, these boxes are calculated, you can get different number of boxes, so it is not difficult to choose the box shape suitable for loading containers. At the same time, it can also adjust the shape and improve the box shape according to the needs.

The optimum box shape can generally be determined. The box shape of most goods can have a variety of configurations, and it is always possible to find one of the most suitable box shape for loading containers. We can follow this principle to think and find, it is not difficult to achieve the purpose: 1) whether the packing rate of the goods can be changed, the number of packing is different, the shape of the size must be different; 2) Whether the arrangement of the goods can be changed, the arrangement is different, the overall size will be different; 3) Whether the opening direction of the packing box can be changed, the opening direction is different, and the outline size is necessarily different (the opening direction packaging size is larger than other directions).

2, the establishment of the expression of the intention to communicate the packaging from the design of the packaging box to the shipping of the packaging box, at least three units, that is, the manufacturer, the business enterprise, the container station, which lasted for ten days. Therefore, the intention of packing should have a clear expression for everyone. Generally simple stacking can be expressed through language, text, or layered plane plans, but to express more complex packing methods, especially several packing methods, these methods are difficult to express clearly. Through our long-term understanding of the container loading and unloading process, we use the main diagram to express, which can intuitively reflect the three-dimensional orientation and legend of each arrangement, so as to facilitate the packing operation. The dimensions are marked comprehensively, which facilitates checking the reserved gaps in each direction of the container. The production of three-dimensional diagram is also very simple, the drawings and the orientation of the packaging box are printed in advance, and the use of only a few parallel lines on the drawing, fill in the numbers, and cut and paste it.

3, the establishment of standard boxes and databases for the design of packaging boxes In order to more convenient to find out the size of the container, according to the different specifications of various containers, respectively prepared different standard box specifications, and usually a variety of high utilization rate, loading more successful box assembly, the establishment of a database for measurement, determine the size of the box reference. Try to use standard boxes or boxes with high utilization rate, which can improve the design speed. As long as we continue to accumulate data and experience, the design of packaging boxes will be done faster and better.

Taking full advantage of the new situation and prospect of containers, our company has adopted new technologies to increase container loading capacity, and now it has reached the following levels: a 20-foot container can hold 30-3m3, not less than 2m3; A 40-foot container can hold 60-64m3, not less than 58m3, and the utilization rate can reach 90%-96%. Each container can hold an extra 3-9m3 of cargo. As the utilization rate of packing boxes and containers has been improved, the loading capacity of some commodities has been greatly improved. For example, the main export products of our company are full-eye children's clothes and full-eye pants, and the loading capacity of 20 British flying containers has been increased from 2500 dozen to 3500 dozen, increasing the loading capacity by 40%.

Now each freight per cubic meter LCL price 50-230 US dollars, package price 40-150 US dollars, each container can save freight of more than 100 US dollars. In 2010, our company saved about 45,000 US dollars in freight for the whole year. This technology has not yet been fully rolled out, if it is fully rolled out, it can save more freight.

After the application of this scientific and technological achievement, it has not only brought considerable economic benefits to our company, but also brought changes to the spiritual outlook of our employees. Now the salesman really pay attention to the packaging and transportation work, as long as the production of a box of goods, they will design the packaging box with the manufacturer, make full use of the container capacity, and consider the maximum number or quantity range of the entire container when ordering.

Manufacturers have also undergone gratifying changes, they have changed the backward original design method, before the design of the packaging box, to understand the calculation theory, understand the container information, and the salesman to discuss the program, with measuring tools to measure, calculate, and compare repeatedly before finally determining the box. After packing, the actual size should be reported to the business unit.

Since the manufacturer and the business enterprise have made the preliminary preparation for the packing, the container station can be operated in accordance with the packing diagram. In this way, the packing speed can be accelerated and the service quality can be improved.

There are a lot of goods transported by container shipping and packaging, and the container freight is high. If we can pay attention to the packaging and transportation of each batch of goods, we can save a very considerable freight. If this technology is promoted throughout the country, all enterprises in the country, no matter which factory produces and processes the products, and no matter where the containers are packed, have reached the purpose of making full use of the containers, then the national annual savings in freight will reach hundreds of millions of dollars.
