Norma ASTM F88

Test Materials: ASTM F88 specifies the use of flexible barrier materials, such as plastic films, laminates, and foils, typically used in packaging. The test is designed to assess the strength of seals formed between these materials under specific conditions. Samples must be prepared with uniform seals to ensure accurate testing.
Test Process: The seal strength test involves applying a controlled force to the sealed area of the material, using a tensile tester. The sample is pulled at a consistent speed, and the maximum force required to break the seal is recorded. The test conditions, including the sample’s dimensions, temperature, and humidity, should be controlled as per ASTM guidelines.
Test Result Interpretation: The results are interpreted based on the maximum force required to break the seal. A higher force indicates stronger seal integrity, while a lower force suggests weaker sealing. These results are critical for determining the durability and reliability of packaging seals, ensuring they meet performance standards for product protection.
