Exposure to vibration can affect the shipping container, its interior packaging, means of closure, and contents. These tests allow analysis of the interaction of these components

Loose Load Vibration Methods

When it comes to loose load vibration and fixed displacement vibration testing, there are three areas of focus that Test-O-Pac uses to assess a package’s ability to protect products. These include:

1) Transit Environment
Different transportation solutions expose packages to different vibration stressors. These stresses are simulated in the laboratory and the results of our tests provide critical information to package manufacturers in order to assist them in creating superior packing solutions.

2) Operational environment
After transit, products and packaging are subjected to additional vibrations as they are moved around the storage facility using equipment. Once again, Test-O-Pac’s tests ferret out weaknesses in package design and the results are provided to manufacturers in order to create better packaging.

3) Warehousing environment
Last but not least, products and packaging experience vibration during storage occurs while they are stored on shelves and flooring due to vibrations given off by climate control systems, equipment and passing vehicles.

Our Methodology

Test-O-Pac’s testing methodology covers a variety of packaging materials as well as vibration stressors. Tests such as the bounce test and ASTM D642 are designed to test the package’s durability and ability to protect its internal contents under specific conditions. Each test is designed to fully test the viability and performance of each container and its ability to protect its contents when subjected to vibrations. Test-O-Pac’s testing methodology meets the requirements of International Organization for Standardization standards ISO 8318 and ISO 2247.


In particular, exposure to loose load vibration can have a significant impact on the shipping container, its interior packaging components, and its contents. Test-O-Pac’s tests allow researchers the ability to analyze the interaction of each of these components in order to determine the best way to minimize damage. Design modifications are based on the results of the test to achieve optimum performance in all aspects of the shipping and storage environments. Whenever possible, laboratory results are compared to real world data in order to understand the common failures of packaging in the real world.
