How to Test Seal Strength of Peel Lids According to ASTM F2824 and ISO 17480 Standards
Ensuring the integrity and safety of sealed packaging is critical across various industries, including food, medical, and pharmaceuticals. The seal strength of peel lids is a key factor in maintaining product quality and preventing contamination. In this article, we will explore how to test the seal strength of peel lids according to ASTM F2824 and ISO 17480 standards.
I. Understanding Seal Strength of Peel Lids
The seal strength of peel lids refers to the force required to peel or separate the lid from its container. This parameter is crucial in assessing the packaging’s ability to protect its contents effectively. Inadequate seal strength can lead to leaks, contamination, and compromised product integrity.
ASTM F2824 and ISO 17480 Standards
To standardize the testing process, ASTM F2824 and ISO 17480 provide detailed procedures and requirements. These standards ensure consistency, reliability, and comparability of test results across different testing scenarios.
II. ASTM F2824 Standard
1. Purpose and Scope
The ASTM F2824 standard, titled “Standard Test Method for Mechanical Seal Strength Testing for Round Cups and Bowl Containers with Flexible Peelable Lids,” outlines specific procedures for measuring the mechanical seal strength of round cups and bowl containers with flexible peelable lids. This standard aims to provide a consistent method for assessing seal strength, ensuring reliability and reproducibility.
2. Test Methods and Procedures
Calibration and Setup
- Calibration: Ensure the force-measuring device is calibrated to maintain accuracy.
- Setup: Secure the container and lid in the test equipment fixture, aligning the peel line with the direction of the test.
Conducting the Test
- Attach the Lid: Secure the lid’s peeling tab to the grip of the force-measuring device.
- Set the Peel Rate: Adjust the peel rate to 12 ± 0.5 in./min (300 ± 12.7 mm/min).
- Initiate the Test: Begin the test and record the force required to peel the lid.
Interpreting Results
Analyze the data focusing on maximum, minimum, and average forces. Compare the results with industry standards to determine compliance.
III. ISO 17480 Standard
1. Purpose and Scope
The ISO 17480 standard, “Packaging — Accessible Design — Ease of Opening,” complements ASTM F2824 by providing guidelines for the ease of opening of packaging. This standard emphasizes user-friendliness and accessibility, ensuring that packaging can be easily opened by consumers, including those with limited dexterity.
2. Test Methods and Procedures
Calibration and Setup
- Calibration: Confirm the calibration of the testing device to ensure accurate measurements.
- Setup: Properly secure the container and lid in the testing apparatus.
Conducting the Test
- Attach the Lid: Connect the lid’s peeling tab to the testing device.
- Set the Parameters: Adjust the testing parameters according to ISO 17480 guidelines.
- Initiate the Test: Conduct the test and record the force required to peel the lid.
Interpreting Results
Evaluate the results based on maximum, minimum, and average forces. Ensure the packaging meets the ease of opening requirements specified in ISO 17480.
