Aluminum cosmetic packaging parameters

Aluminum cosmetic packaging has become the first choice for high-end brands by virtue of its light weight, high sealing and strong environmental friendliness, and is suitable for a wide range of products such as liquids, creams and sprays. Its core parameters (such as thickness, temperature resistance, capacity) can be flexibly customized according to the needs, and in line with the global trend of environmental protection.

I. Core Material Characteristics

• Lightweight and durable

Aluminum has a low density (about 2.7g/cm³), which is more than 50% lighter than glass, and is highly impact-resistant, with a breakage rate of less than 1% during transportation.

Surface plating (e.g., alumina) enhances corrosion resistance and adapts to cosmetic formulations with a pH of 3-11.

• Sealability and Light Avoidance

Aluminum tubes/bottles are seamlessly welded for IP67-level sealing, effectively isolating oxygen and moisture and extending the shelf life of cosmetics by 1-2 years.

Aluminum is 99% impervious to light, preventing UV rays from causing active ingredients to decompose (e.g. vitamin C, retinol).

II. Common Structure Types and Parameters

• Aluminum tube 

- Pure aluminum or aluminum-plastic composite (PE+aluminum) material 

- Thickness: 0.2-0.5mm

- Temperature resistance: -20°C~80°C

- Capacity: 5-100mL (e.g. 5mL mini perfume aluminum tube)

• Aluminum bottle/can 

- One-piece molding + oxidation treatment process 

- Diameter: 17-50mm

- Compressive strength ≥0.8MPa

- Surface can be silkscreen / hot stamping (resolution ≥ 300dpi)

• Aluminum-plastic hose 

- inner PE + outer aluminum composite 

- layer thickness: 0.1mm (aluminum) + 0.3mm (PE)

- Tail sealing method: Straight/twill/shaped tail sealing

III. Environmental performance and sustainability

Recyclability: Aluminum recycling rate ≥95%, carbon emissions 60% lower than plastic, in line with EU REACH environmental standards.

Low-carbon process: adopting cold rolling molding technology, the production energy consumption is 40% lower than that of glass bottles.

IV. Application Scenarios and Applicable Products

• Liquid Cosmetics

Aluminum bottle: suitable for perfume, serum, etc. 5mL mini aluminum bottle is easy to carry around.

Aluminum cans: suitable for spray products (such as sunscreen spray), pressure resistance up to 1.2MPa.

• Cream products

Aluminum tube: face creams, hand creams, etc., with residue of ≤1% in extruded design.

Aluminum-plastic hose: eye cream, concealer, can be customized flat tube / oval tube shape.

V. Market Trends and Innovative Designs

Portability: 5-10mL mini-aluminum tube packaging has become the mainstream of travelwear, weighing only 10-20g.

Intelligent packaging: Aluminum bottles with integrated RFID chips for anti-counterfeiting and dosage tracking.

VI. Aluminum cosmetic bottle appearance advantages

1. Metallic luster and high-grade feeling

The surface of aluminum bottles is oxidized or polished, presenting a unique metallic luster, which, together with the simple line design, can enhance the high-end visual experience of cosmetics.

Diversified surface treatment processes such as matte and mirror (e.g. anodizing) meet the needs of different brands for texture.

2. Lightweight and Portability

With the low density of aluminum (2.7g/cm³), the weight of the bottle is only 1/3 that of glass, making it easy for consumers to carry around while maintaining structural stability.

3. Shaped bottle customization

Aluminum has strong ductility and can be stamped into cylindrical, polygonal, curved streamlined and other shaped bottles, such as flat elliptical tubes, angular geometric shapes, to enhance product recognition.

Support three-dimensional processes such as embossing, hollowing, etc., such as engraving brand logos on the cap or bottle body to strengthen the brand memory point.

4. Printing and color adaptation

The surface of aluminum bottles can realize high-resolution patterns (≥300dpi) through silkscreen, hot stamping, UV printing and other processes, and adapt complex color effects such as gradient and pearlescent.

The printing layer has strong adhesion and high abrasion resistance, so it is not easy to fade or scratch in long-term use.

5. Sustainable aesthetics

Aluminum bottle recyclable characteristics (recycling rate ≥95%) and minimalist design fusion, catering to young consumers' dual pursuit of environmental protection and minimalism.

6. Miniaturization Trend

5-10mL mini aluminum bottles (e.g. perfume travel size) combine practicality and display aesthetics through compact shape + metallic texture.
