Containers and packing are exposed to various types of stress while being filled, moved, stored and transported. But there are several methods used to test packaging products, and there are specific tests that can be applied to a particular design or material being used.
These tests help ensure that your packaging needs are met, depending on the type of product you are packaging and the modes of transportation that will be used to deliver it to your customers. If you’re looking for information on packing testing then contact us by browsing online.
There are two main stress points in packaging:
Mechanical stresses: the most common mechanical stresses in transported products are force stresses, such as stacking pressure, impacts, vibrations and falls.
Climatic stress: Climate plays a vital role in packaging durability and performance, particularly during storage and transportation.
Fortunately, test designs exist to assess the performance of containers, regardless of how they may be exposed to these kinds of stresses and strains. Even when a packaging solution is too impractical to test in the conventional way, computer analysis can do the testing.
Many packaging stresses and strains can be accurately tested, including the following:
- Compression/stacking performance is tested by applying and releasing pressure, and by applying and holding pressure.
- Vibration can be tested horizontally, vertically, or on a multi-axis, and the amount of vibration can also be calibrated to test degrees of vibration intensity.
- Impact tests can be performed in a variety of ways, including free falls, rotational impact, impacts applied to hazardous material packaging, tilted impacts, drops, and more.
- Temperature and atmospheric stress tests can include various degrees of humidity and temperature cycling.
Other tests include water spray and testing of corrugated packaging materials and designs.
