Aluminum Foil is a highly versatile metal material renowned for its exceptional barrier properties against moisture, oxygen, light, and contaminants. Engineered from high-purity aluminum alloys, aluminum foil plays a vital role across flexible packaging, food processing, pharmaceutical blister packs, thermal insulation, and industrial manufacturing.

At XQJ Metal (xqjmetal.com), we manufacture and supply premium aluminum foil rolls, jumbo coils, and customized sheets in a wide spectrum of alloys, tempers (O, H14, H18, H22, H24), thicknesses (0.006mm to 0.2mm), and custom widths. Produced with state-of-the-art cold rolling technology, our products ensure precise gauge control, clean pinhole-free surfaces, and superior mechanical performance for demanding global applications.

Popular Aluminum Foil Alloy Grades:

• 8011 Aluminum Foil: The industry standard for food containers, household packaging, bottle caps, and pharmaceutical foil. Offers excellent tensile strength, deep-drawing capability, and thermal endurance.

• 8079 Aluminum Foil: Engineered for ultra-high barrier flexible packaging, medical laminates, and retort pouches, featuring high elongation and superior sealing integrity.

• 1235 Aluminum Foil: High-purity aluminum foil (AL >= 99.35%) widely specified for cable wrapping, transformer coil insulation, tape backing, and electronic shielding.

• 1100 & 3003 Aluminum Foil: High-performance alloys ideal for air conditioner heat exchanger fins, honeycomb cores, automotive heat shields, and industrial ducting.

Frequently Asked Questions (FAQ):

Q: What aluminum foil alloys do you supply for packaging applications?

A: We mainly produce 8011, 8079, and 8021 aluminum foils in soft temper (O) for packaging. Grade 8011 is cost-effective for general food containers, while 8079 and 8021 offer superior ductility for deep-drawn pharmaceutical blister packs and high-barrier pouches.

Q: Can you provide custom slitting and jumbo foil roll widths?

A: Yes. We operate precision slitting machinery that can slice jumbo coils to your required custom widths from 100mm up to 1600mm with tight width tolerances and clean burr-free edges.

Q: What is the difference between single-zero foil and double-zero foil?

A: Single-zero foil refers to thickness between 0.01mm and 0.1mm (one zero after decimal), common in containers and household foil. Double-zero foil refers to thickness below 0.01mm (e.g., 0.006mm – 0.009mm, two zeros after decimal), typically used for high-end flexible packaging and laminations.

Q: Do you provide MTC (Mill Test Certificate) for aluminum foil orders?

A: Yes, all XQJ Metal aluminum foil shipments include EN 10204 3.1 Mill Test Certificates and FDA/EU food-grade compliance reports.

Q: What is the MOQ and lead time for aluminum foil wholesale?

A: Our standard MOQ is 1–3 metric tons depending on the alloy grade and thickness. Standard delivery lead time is 15–20 days.
