Double Zero Aluminum Foil

Double zero aluminum foil is a "double-zero foil" with a thickness of only 0.007 mm, making it one of the mainstream specifications in the high-barrier packaging sector. Like other double-zero foils, it achieves a good balance between cost-effectiveness and ease of use, which is why it has broader market applications than 6-micron foil.

Commonly used alloys include 1235, 8011, and 8079. The choice of alloy specifically affects its mechanical properties and cost. The most common temper is O-temper (fully soft), which has been completely annealed and offers the highest flexibility. Manufacturing tolerance is typically within ±0.5 µm.

The elongation of double zero aluminum foil is typically between 10% and 35%, indicating that it can withstand significant plastic deformation before fracture. It is generally left in its as-rolled condition, with one bright side and one matte side. It provides nearly complete barrier against oxygen, moisture, light, and volatile substances, with a water vapor transmission rate (WVTR) approaching zero.

double zero aluminum foil plays a key role in various high-barrier packaging applications, especially in the food sector. It often appears as the "functional layer" in composite materials.

Food & Beverage Packaging

• Tetra Pak / Beverage Cartons: Used as a multi-layer composite aseptic packaging material for long-term preservation of liquid foods such as milk and juice.
• Flexible Pouches & Retort Pouches: Laminated with PET plastic film to make food packaging pouches, retort pouches, and stand-up pouches, providing freshness preservation, moisture resistance, and high barrier properties.
• Daily Food Packaging: Made into various flexible packaging bags and lidding films for snacks, candies, chocolates, seasoning packets, etc.

Pharmaceutical & Health Product Packaging

• Pharmaceutical Blister Packaging: Used for blister packs (PTP) for capsules and tablets – one of the core pharmaceutical applications of 7-micron foil. It offers high barrier properties and flexibility, making it easy to form.
• Medical Pouches & Blister Packaging: Used for high-barrier packaging of medical devices and hygiene products.

Cosmetic & Consumer Goods Packaging

• Cosmetics & Personal Care: Used in flexible packaging for face mask pouches, cream samples, shampoo sachets, etc. It can be printed with fine patterns and protects contents from oxidation.
• High-End Consumer Goods: Used in packaging for chocolate gift boxes, premium tea, electronic products, etc.

Industrial & Building Material Applications

• Thermal Insulation Materials: Laminated with kraft paper, etc., for moisture barrier facings in building insulation layers and HVAC ducts, reflecting thermal radiation.
• Home Cooking: Although thinner than dedicated household foil, some high-quality 7-micron foil can also be used for grilling, baking, etc.

Thank you for choosing Yongsheng Aluminum Foil Roll. For best performance, please follow these guidelines:

• Storage: Keep in a cool, dry place away from direct sunlight and moisture.
• Cutting: Use a sharp cutter or built-in serrated edge for a clean cut; avoid tearing by hand.
• Handling: Unroll slowly and keep taut to prevent creases and tears.
• Cleaning: For single use only. Dispose of responsibly by recycling where possible.
• Safety: Keep away from electrical outlets and open flames. When using in a microwave, avoid contact with oven walls.
