Every aerosol product starts with the same fundamental question: what kind of aerosol can will best deliver this formulation? The container is more than just a vessel—it must withstand internal pressure, resist corrosion, complement the brand aesthetic, and perform reliably from the first spray to the last.
This guide covers the major aerosol container types, materials, manufacturing methods, and key criteria for selecting an aerosol can supplier.
What Is an Aerosol Can?
An aerosol can (气雾罐) is a pressurized container designed to hold and dispense products through a valve and actuator system. The container must maintain pressure resistance and hermetic properties to keep the propellant contained and the product stable throughout its shelf life.
Aerosol containers come in various materials, sizes, and configurations depending on the product category—personal care, cosmetics, household cleaners, or industrial sprays.
Every aerosol package consists of four core elements:
- Product concentrate – the active formulation
- Propellant – liquefied or compressed gas
- Container – the metal structure
- Valve and actuator – the dispensing mechanism
Types of Aerosol Containers
Aerosol cans fall into two primary material categories: aluminum and tinplate steel. Each has distinct advantages.
Aluminum Aerosol Cans
Aluminum cans are manufactured as monoblock containers through a process called impact extrusion. The seamless body offers:
- Smooth, flawless surface – ideal for high-end decorative printing
- Lightweight – reduces shipping costs
- 100% recyclable – strong sustainability profile
- Corrosion resistance – suitable for water-based formulations
Aluminum cans dominate the cosmetic and personal care segment, including deodorants, hair sprays, and facial mists.
Tinplate Steel Aerosol Cans
Tinplate cans are typically 3-piece welded containers (side-seam can). They offer:
- Higher pressure tolerance – suitable for industrial and household products
- Lower material cost – more economical for high-volume production
- Excellent printability – supports vibrant brand graphics
Steel cans are commonly used for paints, insecticides, air fresheners, and automotive products.
Container Shapes
Beyond material, aerosol cans are available in multiple shapes:
- Straight wall – standard cylindrical design
- Necked-in – reduced diameter at the top for smaller caps
- Shaped – custom contours for brand differentiation
Other Container Materials
While metal dominates the market, aerosol containers can also be made from glass (pharmaceutical applications) and plastic (limited pressure applications).
Key Components of an Aerosol Package
An aerosol package is more than just the can body. The complete system includes:
| Component | Function |
|---|---|
| Container body | Holds pressurized contents; withstands internal pressure |
| Valve | Controls release rate and flow |
| Actuator | The button pressed by the user; determines spray pattern |
| Dip tube | Extends from valve to container bottom; draws product up |
| Mounting cup | Secures the valve to the container |
| Overcap | Protects actuator; prevents accidental discharge |
Each component must be compatible with the formulation to prevent corrosion, clogging, or performance degradation.
How Aerosol Cans Are Manufactured
The aerosol can manufacturing process varies by material.
Aluminum Can Production (Impact Extrusion)
Aluminum slugs are fed into high-tonnage impact extrusion presses. The metal flows upward around a punch die to form a seamless container body. Key steps include:
- Slug lubrication – prepares the aluminum slug for forming
- Backward impact extrusion – shapes the can body
- Wall ironing – thins and strengthens the walls
- Trimming and necking – shapes the open end
- Surface treatment – chemical cleaning and conversion coating
- Interior coating – epoxy-phenolic spray coatings prevent oxidation
- Decoration printing – multi-color dry-offset printing applies brand artwork
Tinplate Can Production (3-Piece Welded)
Tinplate cans are formed from three pieces: body, bottom, and top. The body is rolled from flat steel sheet, welded along the seam, and flanged at both ends to accept the bottom and top.
Quality Considerations
Cans must withstand internal pressures ranging from 0.2 to 0.9 MPa at ambient temperatures. Structural defects, coating integrity, and dimensional accuracy are verified through automated optical inspection.
How to Choose an Aerosol Can Supplier
Selecting the right aerosol can supplier directly impacts product quality, production efficiency, and brand reputation. Consider these criteria:
1. Material Expertise
Does the supplier specialize in aluminum or tinplate? Do they offer both? The right material depends on your formulation, pressure requirements, and aesthetic goals.
2. Customization Capabilities
Can the supplier provide custom diameters, heights, neck profiles, and decorative finishes? For brands seeking differentiation, shaped cans and embossed designs offer significant shelf appeal.
3. Coating and Lining Quality
Interior coatings prevent product-container interaction. A reputable aerosol container manufacturer applies and thermally cures protective linings to ensure long-term stability.
4. Production Capacity and Lead Times
High-volume brands need a supplier with automated production lines and consistent output.
5. Regulatory Compliance
The supplier should meet relevant standards for pressure resistance, material safety, and food/pharmaceutical-grade requirements where applicable.
6. Sustainability Commitment
Aluminum aerosol cans are 100% recyclable. Many brands now prioritize suppliers using recycled content and low-carbon manufacturing processes.
Why Container Quality Matters in Aerosol Manufacturing
The aerosol can is the most visible component of your product—and the most critical for safety. A compromised container leads to:
- Leakage – product loss and customer complaints
- Pressure failure – safety hazards during shipping or use
- Corrosion – contamination of the formulation
- Poor spray performance – valve misalignment from deformed containers
Working with an experienced aerosol can supplier ensures every container meets structural, aesthetic, and regulatory standards before filling begins.

Frequently Asked Questions About Aerosol Can Packaging
What is an aerosol can?
An aerosol can is a pressurized container that holds and dispenses products using a propellant. It must maintain pressure resistance and hermetic sealing.
What are the main types of aerosol containers?
The two primary types are aluminum monoblock cans (seamless, impact-extruded) and tinplate steel 3-piece welded cans.
What materials are used for aerosol cans?
Aluminum, tinplate steel, glass, and occasionally plastic.
What is the difference between aluminum and tinplate aerosol cans?
Aluminum cans are seamless, lighter, and preferred for cosmetics. Tinplate cans are welded, more pressure-resistant, and cost-effective for household and industrial products.
How are aerosol cans manufactured?
Aluminum cans use impact extrusion; tinplate cans use welded 3-piece construction.
What should I look for in an aerosol can supplier?
Material expertise, customization capabilities, coating quality, production capacity, regulatory compliance, and sustainability practices.
