What is the impact of containerization?

Containerization is the process by which goods that previously used to be transported in breakbulk are being shipped in standardized units. Containerization has revolutionized cargo shipping. The widespread use of ISO standard containers has driven modifications in other freight-moving standards, gradually forcing removable truck bodies or swap bodies into the standard sizes and shapes (though without the strength needed to be stacked), and changing completely the worldwide use of freight pallets that fit into ISO containers or into commercial vehicles. Improved cargo security is also an important benefit of containerization. The cargo is not visible to the casual viewer and thus is less likely to be stolen and the doors of the containers are generally sealed so that tampering is more evident. This has reduced the "falling off the truck" syndrome that long plagued the shipping industry. Use of the same basic sizes of containers across the globe has lessened the problems caused by incompatible rail gauge sizes in different countries.
