How to Test The Quality of Aluminum Easy Peel Off End

In the flexible packaging industry, aluminum foil is widely used, and it is no exception in the easy peel off end. Aluminum easy tear lid the most widely used easy-to-peel sealing film packaging products on the market. The application of aluminum foil for bottle cap makes food products have certain anti-theft properties.
At the same time, aluminum foil easy peel off caps have good moisture resistance and sealing properties, and are easy to operate during packaging. Therefore, aluminum foil easy-to-peel cover materials can be used in beverage bottles, glass bottles, yogurt cups and other product packaging. What are the inspection items for aluminum foil easy-tear lids? What specific project indicators are included?

1. Appearance inspection: Evaluate the surface quality of the aluminum foil easy-tear cover, including color, gloss and any visible defects.

2. Dimension measurement: The dimensions of the aluminum foil easy-tear lid meet the design specifications and ensure that it can fit the corresponding container.

3. Material analysis: Determine the specific material composition of the aluminum foil sealing to ensure that the aluminum foil sealing meet the standard requirements.

4. Sealing performance test: Detect the sealing strength and sealing integrity when the easy-tear cover is closed with the container to prevent leakage.

5. Easy-tear performance test: Evaluate the difficulty of users opening the easy-tear cover when using it to ensure that it is easy to tear manually.

6. Pressure resistance test: verify the stability and durability of the aluminum foil easy-tear cover when subjected to external pressure.

7. Temperature resistance test: test the performance stability of the aluminum foil easy-tear cover under high and low temperature environments.

8. Chemical corrosion resistance test: Evaluate the corrosion resistance of the tear-off cover to various chemicals to meet the needs of different packaging contents.

9. Microbiological testing: confirm whether the tear-off cover is contaminated by microorganisms during production and storage to ensure product safety.

10. 10. Heavy metal content testing: ensure that the heavy metal content in the aluminum foil tear-off cover does not exceed the prescribed safety standards to avoid health risks.

11. Test of the adhesion strength between the tear-off cover and the aluminum foil: measure the adhesion between the tear-off cover and the 8011 aluminum foil to ensure that it does not fall off during transportation and use.

12. Wear resistance test of easy-tear cover: evaluate the wear resistance of the easy-tear cover surface under long-term friction to ensure that the appearance and function are not damaged.

13. Impact resistance test of easy-tear cover: determine whether the easy-tear cover can remain intact when suddenly impacted.

14. Aging resistance test of easy-tear cover: test the changes in physical and chemical properties of the easy-tear cover under long-term natural or accelerated aging conditions.

15. UV resistance test of easy-tear cover: evaluate the durability and protection effect of the easy-tear cover under ultraviolet light.

16. Water vapor permeation resistance test of easy-tear cover: measure the ability of the easy-tear cover to block water vapor penetration to protect the contents from moisture.

17. Grease permeation resistance test of easy-tear cover: verify the barrier ability of the easy-tear cover for grease and other non-polar solvents.

18. Gas permeation resistance test of easy-tear cover: ensure that the easy-tear cover can effectively prevent the penetration of oxygen and other gases and maintain the gas composition inside the package.

19. Low temperature resistance test of easy-tear cover: Test the physical stability and performance of the easy-tear cover in a low temperature environment.

20. High humidity resistance test of the easy-tear cover: Confirm that the physical properties and functionality of the easy-tear cover remain unchanged in a high humidity environment.
