How To Test Bottle Sealer Foil Film

With the continuous advancement of modern packaging technology, bottle sealer foil has been widely used in food, medicine, cosmetics and other fields. Aluminum foil sealing film has good sealing performance and oxygen barrier performance, which can effectively protect the quality and safety of products. However, due to the complexity of the production process, aluminum foil sealing film may have quality problems, so strict testing is required.

1. Size detection

The size of the aluminum foil for bottle cap is crucial to the packaging sealing of the product. By measuring the width and length of the aluminum foil sealing film, it can be ensured that they meet the specified size standards. Size detection is generally carried out by optical microscope or measuring instrument.

2. Thickness detection

The thickness of the aluminum foil sealing directly affects its sealing performance and oxygen barrier performance. By using a thickness measuring instrument, the thickness of the aluminum foil sealing film can be accurately measured and controlled. In order to ensure the quality consistency of the product, multi-point thickness detection is also required to detect any possible problems.

3. Strength test

The strength of the aluminum foil sealing film is very important for the wear resistance and tear resistance during transportation and use of the packaging process. Strength testing can be carried out by adopting tensile tests or tear tests to evaluate the physical strength and durability of the aluminium foil for induction sealing.

4. Tensile performance test

Tensile performance refers to the ductility and resilience of the seal aluminium foil under the action of external force. The quality of tensile performance directly affects the sealing effect and packaging quality. Through the tensile test instrument, the deformation degree and recovery of the seal aluminium foil during the stretching process can be tested.

5. Permeability test

The oxygen barrier performance of the aluminum foil sealing film is one of its important functions. Aluminum foil sealing films with good oxygen barrier performance can effectively prevent the penetration of oxygen and extend the shelf life of the product. Permeability testing is usually carried out by instruments such as gas permeameters to evaluate the gas permeability of aluminum foil sealing films.

6. Sealing performance test

The sealing performance of the bottle aluminium seal is one of its most important functions. The quality of sealing performance is directly related to the quality and safety of the product. The sealing performance test is usually carried out using a sealing tester to evaluate the sealing effect of the aluminum foil under different temperature and pressure conditions.

7. Printing quality test

The printing quality on the AA 8011 aluminum foil sealing has an important impact on the packaging appearance and brand image of the product. Printing quality inspection mainly includes the clarity of the printed pattern, the vividness of the color and the adhesion of the printed layer.

Through strict control and evaluation of these testing items, the quality stability of aluminum foil sealing and packaging safety of products can be ensured. At the same time, continuously improving testing technology and methods to improve the performance and quality of aluminum foil sealing film is the future development direction.
