Compression Package Testing
Testing for compression determines how well packaging holds up under steady stress. Testing of this kind may be carried out mechanically, pneumatically, or hydraulically. It is intended to apply a predefined load to a package or container, whether it is full or empty.
Compression testing and stacking testing are conducted in very similar ways. Over a predetermined period—or until collapse—a predetermined load is maintained. In the event of a collapse, the amount of time that has passed is calculated, the package’s dimensions are determined, and its contents are scrutinized.
We understand the significance of compression integrity testing because our lab is ISTA and ISO 17025 accredited. It can be challenging to fulfil compliance testing standards. We are aware of the difficulties and help businesses through them. Are you prepared to begin?

Why Are Testing Compression Packages Important?
Packages can be kept in the distribution system for a long time. One or more containers may be piled on top of one another when the shipment is being stored.
Any layer of the packing may experience failure. These failures can cause firms to waste time on return shipments and product repairs, which will result in lost sales, lost customer loyalty, and other problems.
Keystone Compliance strives to execute all necessary tasks and any compression testing that our clients require without ever over-testing packages.
Method for Compression Integrity Testing
Usually, a test lab and manufacturer work together to determine what constitutes a pass or fail test. In many instances, the unit must be undamaged and intact to pass the test. Before the start of the testing, the performance criteria must be set.
Interior packing may or may not be required, depending on the test’s goals. It is advised to use several samples for the majority of testing criteria.
The samples must be prepared for the compression test when necessary by exposing them to set temperatures and humidity levels. The ASTM D4332: Conditioning Containers, Packages, or Packaging Components standard test for conditioning packages specifies the ambient temperatures, relative humidity, and conditioning durations.
After that, a package is subjected to a steady load using a compression machine or weight. Observations are then made. When a collapse happens, details about it are documented. This covers both the container’s and its contents’ damage.
Last but not least, the following details are included in the report. This list does not purport to provide all the information in the study.
- dimensions of the test container,
- If any, a description of the contents
- criteria for acceptance that have been developed,
- the test’s date, time, and the engineer’s name,
- any exercise performed,
- a summary of each container’s test findings.
Infinita Lab Compression Test Tools and Resources
There are several compression/tensile testers in our brand-new laboratory for evaluating packages. We have dozens of climatic chambers with shakers up to 12 kips and sizes up to 1,300 cubic feet.
Compression Resistance of Containers: ASTM D4577 is intended to apply a specified static load to a container, whether it is empty or filled.
Palletized or unitized load configurations are covered by ASTM D4577. A phase of the distribution system allows for the storage of packages for a predetermined amount of time. One or more containers may be stacked on top of one another when these goods are kept.
Compression and stacking, ISO 12048
used to simulate stacking, where the test examines performance under specific load situations.
A package’s performance in terms of strength or the protection it provides for its contents is evaluated according to ISO 12048. When the unit is subjected to compressive forces, this test is relevant. The test procedure runs until a failure happens or until a specific load is imposed for a specific amount of time.
