The Fortress of Packaging: Aluminum Aerosols

Engineering Specs: Why Aluminum Wins

Aluminum is unique in the packaging world. It offers the barrier properties of metal with the lightweight characteristics of plastic. At Golden Soar, we specialize in Monoblock Aerosol Cans et Threaded Aluminum Bottles.

1. The Monoblock Advantage

Unlike 3-piece tinplate cans which have a welded side seam, our aluminum cans are impact-extruded from a single piece of metal. This “Monoblock” structure eliminates the weakest point of a can—the seam. This allows our standard cans to withstand internal pressures of 12-18 Bar, making them the safest choice for high-pressure propellants (LPG/Propane) used in hairsprays, deodorants, and shaving foams.

2. Internal Lining (BPA-Ni)

Raw aluminum can react with certain formulations (especially acidic ones). To prevent corrosion and product contamination, every can is sprayed internally with a protective lacquer. We use BPA-Ni (Non-Intent) Epoxy-Phenolic or Polyester resins. This coating is cured at high temperatures to form an inert barrier, ensuring your formula never touches the raw metal. This is critical for pharmaceutical and sensitive cosmetic applications.

3. Dry-Offset Printing

Decoration is applied directly to the cylindrical surface using high-speed dry-offset printing. We can apply up to 9 colors in a single pass. This eliminates the need for adhesive labels, giving the product a premium, seamless look that is waterproof and scratch-resistant. We also offer special finishes like:

• Matte/Gloss Combo: Spot varnish effects.
• Brushed Aluminum: Using transparent inks to show the raw metal grain.
• Pearl/Metallic Inks: For a shimmering effect.
