单元化的概念包含两个方面: 一是对物品进行单元化的包装，（即标准的单元化物流容器的概念）将单件或散装物品，通过一定的技术手段，组合成尺寸规格相同，重量相近的标准“单元”。而这些标准“单元”作为一个基础单位，又能组合成更大的集装单元。
The concept of unitization includes two aspects: one is the unitized packaging of goods (i.e. the concept of standard unitized logistics container). Single or bulk goods are combined into standard "units" with the same size and specification and similar weight by certain technical means. As a basic unit, these standard "units" can be combined into larger container units.
二是围绕这些已经单元化的物流容器，它们的周边设备包括工厂的工位器具的应用和制造也有一个单元化技术的含义在里面，包括规格尺寸的标准化，模块化的制造技术和柔性化的应用技术。
Second, around these already unitized logistics containers, their peripheral equipment, including the application and manufacturing of the factory's working position instruments, also has a meaning of unitization technology, including the standardization of specifications and sizes, modular manufacturing technology and flexible application technology.
从包装的角度来看，单元化是按照按一定单元将杂散物品组合包装的形态。由于杂、散货物难以象大型的单件货物那样进行处理，而且体积、重量都不大，总是需要进行一定程度的组合，才能有利于使用，有利于物流活动的开展。
From the perspective of packaging, unitization is the combination of packaging form of miscellaneous items according to a certain unit. Because it is difficult to deal with miscellaneous and bulk goods like large single goods, and the volume and weight are not large, it is always necessary to carry out a certain degree of combination, in order to be conducive to the use of logistics activities.
从运输角度来看，单元化集装所组合的组合体往往又正好是一个装卸运输单位，非常便利运输和装卸。比如托盘或其他集装方式。
From the perspective of transportation, the combination of unitized container is often just a loading and unloading unit, which is very convenient for transportation and loading and unloading. Such as pallets or other containerization.
