Aluminum blister foil, due to its excellent gas barrier properties, is widely used as a capping material in various industries. It provides a reliable and effective barrier that can completely block any gas transmission, including oxygen, moisture, and light. To protection the contents from external factors is crucial, such as pharmaceuticals, healthcare products, food items, and sensitive electronic components. The use of aluminum blister packaging helps ensure product integrity, prolong shelf life, maintain product quality, and enhance safety for both manufacturers and consumers.

The Process of Making Blister Foil
Foil alloy selection: The choice of aluminum alloy for blister foil is important. The alloy needs to have specific properties such as good formability, heat resistance, and barrier properties to protect the contents of the blister package.
Aluminum foil production: The first step is the production of aluminum foil. Aluminum ingots are melted and cast into large rolls or coils of aluminum foil through a continuous casting and rolling process. The thickness of the foil can be controlled during the rolling process.
Foil annealing: The produced foil is then subjected to an annealing process. Annealing involves heating the foil to a specific temperature and then gradually cooling it. This process helps to relieve internal stresses, improve the foil’s mechanical properties, and enhance its formability.
Surface treatment: Blister foil may undergo surface treatments to enhance its properties. This can include applying a protective coating or laminating the foil with other materials to improve its barrier properties and ensure compatibility with the contents of the blister package.
Printing and coating: Blister foil may be printed with branding or product information. Additionally, coatings can be applied to provide specific functionalities such as improved heat sealability or enhanced moisture resistance.
Slitting and cutting: The finished blister foil rolls are slit and cut into the desired widths and lengths. We support customization based on the specific requirements.
