ASTM F904

Test Materials
ASTM F904 specifies the use of flexible packaging materials, including films, pouches, or bags that are sealed with adhesives or heat. Test specimens should be prepared according to the standard dimensions and include various seal configurations to ensure representative results.

Test Process
The test process involves applying a specified force to the sealed packaging to determine its seal strength. Samples are placed in a tensile testing machine, and the force required to break the seal is measured. Conditions such as temperature and humidity should be controlled to ensure consistency during testing.

Test Result Interpretation
Results from ASTM F904 are interpreted by analyzing the seal strength data obtained during testing. The measured force is assessed against the seal area, allowing for the calculation of seal strength in units such as pounds per inch. This information is crucial for evaluating the integrity and reliability of packaging seals for various applications.
