Foil Aluminum anu sering dianggo pikeun bungkusan, khususna pikeun bungkus fotmace, 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: aluminium foil kabentuk tiis 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, biasana antara 20 jeung 25 mikron, but the thickness can vary depending on the application.
Hara enteng: Due to its thin thickness, the material is lightweight and suitable for applications where weight minimization is critical.

Sipat mékanis
Daktilitas: 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.

Sternal Halher
Undektif: Aluminum foil is an excellent barrier to light, oksigén, kalembaban, sareng gas sanés. This makes it ideal for protecting sensitive products from environmental factors.

Ressi korosi: 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.
Sapasang sareng landinat: Aluminum foil can be coated or laminated with other materials such as plastics or paper to enhance specific properties such as sealability, bisa dicitak, or additional barrier functions.

Euwihan ngaranti
Ruksakna tiis: 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.

Kanyataanitas termal: 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.

Kamampuhan dicitak: The smooth surface allows for high-quality printing and is often used for branding, paréntah, and regulatory information.
