Cold-formed aluminum foil is often used for packaging, especially for pharmaceutical packaging, and alu alu foil has unique structural characteristics that are different from other types of aluminum foil and other packaging materials. Alu alu foil has many structural characteristics.

Cold-formed foil material composition: Letër alumini e formuar në të ftohtë is usually made of high-purity aluminum alloys. The choice of alloy affects mechanical properties, such as strength and ductility. Other alloys are sometimes added to enhance specific properties, such as corrosion resistance or formability.

Thickness and weight
Thin gauge: The thickness of aluminum foil is very thin, usually between 20 dhe 25 mikronë, but the thickness can vary depending on the application.
Lightweight: Due to its thin thickness, the material is lightweight and suitable for applications where weight minimization is critical.

Mechanical properties
Duktiliteti: Cold-formed aluminum foil has high ductility, so it can be easily formed into complex shapes without cracking. This ductility is critical for manufacturing blister packs and other packaging formats.

Strength: Despite its thin thickness, it has sufficient tensile strength to provide barrier protection and maintain integrity during the forming process.

Vetitë penguese
Impermeability: Aluminum foil is an excellent barrier to light, oksigjen, moisture, and other gases. This makes it ideal for protecting sensitive products from environmental factors.

Corrosion Resistance: A natural oxide layer forms on the surface of aluminum foil, which resists corrosion and enhances the durability of the package.

Surface Properties
Smoothness: The surface of cold-formed aluminum foil is usually very smooth and reflective. This is very beneficial for aesthetics and printing.
Coatings and Laminates: Aluminum foil can be coated or laminated with other materials such as plastics or paper to enhance specific properties such as sealability, printability, or additional barrier functions.

Formueshmëria
Cold Formability: Unlike thermoformed materials, cold-formed aluminum foil can be formed at room temperature. The material’s ability to undergo significant plastic deformation without heating is its key characteristic.

Forming Techniques: Common forming processes include deep drawing and pressing, which are used to create the detailed and precise shapes required for pharmaceutical blister packaging.

Thermal Conductivity: Aluminum has high thermal conductivity, which is beneficial for certain packaging applications, but also requires careful handling during the forming process to avoid heat-induced deformation.

Thermal stability: Aluminum foil maintains its structural integrity over a wide temperature range, which is important for a variety of storage and use conditions.

Chemical inertness: Aluminum foil is chemically inert in most environments, helping to preserve contents without reacting with them.

Non-toxicity: Aluminum foil is non-toxic and safe for direct contact with food and pharmaceuticals.

Mundësia e printimit: The smooth surface allows for high-quality printing and is often used for branding, instructions, and regulatory information.
