8011 Alum Foil for PP/ROPP Caps and Seal Liner

Aluminum foil has the advantages of moisture-proof, light-shielding, non-toxic and tasteless. As the most popular aluminum foil alloy, 8011 alum foil has the advantages of strong stability, strong sealing, food grade, clean oil removal, few pinholes, good product shape and other advantages in addition to the common advantages of aluminum foil.

8011 aluminum sheet for PP/ROPP caps is mainly used for the packaging of wine, beverages (steamed and non-steamed) and medical and health products, and can meet special requirements such as high-temperature cooking and sterilization.

8011 aluminum alloy is not only a kind of aluminum foil for bottle cap, but also an important alloy of the aluminum sealing foil. The chosen aluminum foil is mainly 8011 aluminum foil. The substrate is the supporting layer of the aluminum foil sealing film, usually made of plastic film or paper.

8011 aluminum foil has good thermal conductivity and insulation, and can effectively block the impact of external temperature and humidity on the product. At the same time, 8011 aluminum foil also has high strength and corrosion resistance, which can protect the product from damage by external physical and chemical factors.

Aluminum foil induction seal liner is suitable for food, spices, detergents, motor oil, cosmetics, etc. The product features are that the aluminum foil sealing film is separated from the padding paper after induction heating, and the aluminum foil sealing layer is sealed with the bottle mouth, which has watertightness, anti-overflow, anti-counterfeiting and freshness preservation.

Aluminum foil testing methods and contents are important links to ensure the quality and performance of aluminum foil products. The following are some methods and contents of aluminum foil testing:

Testing methods

1. Thickness measurement: Use tools such as thickness gauges to measure the thickness of aluminum foil to ensure that it meets relevant standards.

2. Pinhole detection: Perform detection in accordance with national standards to ensure that the aluminum foil has no pinhole defects.

3. Mechanical property test: Perform relevant mechanical property tests such as tensile strength according to the related standards.

4. Surface wetting tension measurement: Measure the surface wetting tension of aluminum foil to evaluate its surface properties.

5. DC resistance measurement: Measure the DC resistance of aluminum foil to evaluate its conductive properties.

6. Heat seal strength measurement: Detect the heat seal strength of aluminum foil, which is particularly important for packaging materials.

7. Metal detection: Use mixed acid to digest the sample to prepare a solution, and perform metal component analysis by flame atomic absorption spectrometry.

Test content:

1. Quality test: evaluate the basic physical and chemical properties of aluminum foil, including its purity and composition.

2. Strength test: test the mechanical properties of aluminum foil such as tear strength and burst resistance.

3. Aging test: evaluate the performance changes of aluminum foil during storage or use.

4. Fire resistance test: evaluate the fire resistance level and performance of aluminum foil.

5. Oxidation test: test the antioxidant properties of aluminum foil.
