Printed Aluminium Blister Foil

Printed aluminium blister foil is a common material used in the packaging of solid products such as pharmaceuticals. It has a complex and sophisticated structure designed to provide excellent sealing, protection and printability.

Printed aluminium blister foil typically consists of a multi-layer structure, with each layer serving a specific function.

1. Printing layer:

The outermost layer is the printing layer, which is used to print product information, brand logos, etc.. According to the demand, it can be printed on one side or both sides, and the pattern and text can be single-color or multi-color, even including anti-counterfeiting design.

2. Protective layer:

Below the printing layer is the protective layer, used to protect the printing layer from damage. Free from external mechanical damage and chemical corrosion. Usually has a certain degree of abrasion resistance and chemical resistance. 3.

3. Aluminum Foil Layer:

The aluminum foil layer is the core part of the blister aluminium foil, which has excellent air barrier and moisture-proof performance to effectively protect the internal products from the external environment. The aluminum foil used for blister packaigng is mainly 8011 H18, 8021 O and so on.

4. Heat sealing layer:

The innermost layer is the heat sealing layer, which is bonded with the plastic hard sheet (e.g. PVC, PVDC, PE, PET, etc.) to form a hermetically sealed package to ensure the sealing performance of the package and prevent the product from leaking.

The thickness of each layer is generally based on specific product requirements, generally speaking, the thickness of the printing layer and the protective layer is thin, the thickness of the aluminum foil layer is thicker, and the thickness of the heat sealing layer is moderate.

Performance characteristics of printed aluminium blister foil are:

1, Oxygen-resistant, moisture-proof, leak-proof, pollution-proof, light-proof: effectively protect the products inside the package from the external environment.

2, Super mechanical properties and corrosion resistance: ensure that the aluminum foil can maintain stable performance in various environments.

3, High barrier properties: excellent barrier properties to moisture, oxygen, other gases, light and ultraviolet rays.

Why is printed aluminium blister foil the popular in pharmaceutical packaging?

1. Excellent protection:

Aluminum foil has good air and moisture barrier properties, which can effectively protect the internal products from the external environment and extend the shelf life of the products.

2. Aesthetics and practicality:

Printed blister foil can be personalized and customized printing, with exquisite appearance, which enhances the product grade and increases the attractiveness of the product.

3. Convenient to use:

Aluminum foil material is light and easy to carry, easy to open and seal, user-friendly.

4. Environmentally friendly and healthy:

Aluminum foil material can be recycled, in line with environmental requirements, and will not cause pollution to the product, to ensure product safety and health.

To sum up, printed aluminium blister foil has the advantages of excellent protection performance, beautiful and practical, easy to use and environmental protection and health, so it is widely welcomed in the packaging industry.
