The Engineering of Excellence: 330ml Aluminum Can Specifications & Advanced 8-Color Printing

In the high-speed beverage industry, a can is not just a container; it is a high-performance pressure vessel and your brand’s most visible ambassador. At Erjin Packaging, we combine metallurgical precision with state-of-the-art printing to ensure your product survives the supply chain and shines on the shelf.

I. Technical Foundation: Built for Durability

Our 330ml aluminum cans are engineered using Aluminum Alloy 3104-H19, the industry benchmark for strength-to-weight ratio. The H19 temper provides the necessary hardness to maintain structural integrity during the rigorous filling and carbonation processes.

Key Performance Metrics:

• Material Precision: Utilizing a coil thickness of $0.270 \pm 0.005$mm, we balance lightweighting with high-pressure resistance.

• Structural Strength: Each can is rated for a minimum Axial Load of 1KN, ensuring stability during stacking and transit.

• Pressure Safety: With a Buckling Pressure of 610 KPa (min), our cans are optimized for highly carbonated beverages, preventing deformation even in fluctuating temperatures.

• Capacity Control: A nominal 330ml volume with an overflow capacity of $356 \pm 3.0$ml ensures consistent fill levels and prevents wastage on your production line.

II. Food-Grade Protection: The Inner Shield

Flavor integrity is non-negotiable. We utilize a high-performance Epoxy inner coating that acts as a total barrier between the aluminum and the liquid. This prevents metallic migration and preserves the original taste profile of your beer, soda, or sparkling water for its entire shelf life.

III. Visual Identity: 8-Color Gravure Printing & Specialty Finishes

To win the “three-second shelf war,” your packaging needs more than just a logo. We utilize an 8-color gravure printing process, which offers a significantly broader graphic range than standard offset printing.

• Metallic Depth: Our gravure process allows for rich, vibrant metallic inks that catch the light and signal premium quality.

• Tactile Finishes: We offer specialized Matte Overvarnish and Partial Matte Printing. A “Matte finish” creates a sophisticated, non-reflective surface that feels premium to the touch, while a “Gloss finish” provides a brilliant, high-shine aesthetic that pops under retail lighting.

• Design Freedom: With 8 colors at your disposal, complex gradients and intricate brand storytelling become possible on a 360-degree cylindrical canvas.

The gravure printing expands the range of graphic expression and allows metallic color printing.

Matte overvarnish and partial matte printing are also available.

“Matte finish” creates a dull surface that is not shiny, while a more shiny surface finish is called “glossfinish.

Frequently Asked Questions (FAQ)

1. Why do you use Aluminum Alloy 3104 for your 330ml cans?

Aluminum 3104 is specifically chosen for its exceptional workability and high tensile strength. The H19 temper (extra hard) allows the can walls to be thin and lightweight while remaining strong enough to withstand the high internal pressures required for carbonated beverages.

2. What are the advantages of 8-color gravure printing over standard offset?

Gravure printing is ideal for high-volume runs requiring consistent, high-definition graphics. It allows for deeper color saturation, finer details, and the seamless application of metallic inks. With 8 colors, you have the flexibility to use multiple spot colors and CMYK for photographic-quality results.

3. Can I combine Matte and Gloss finishes on the same can?

Yes. Through our partial matte printing technology, we can apply matte textures to specific areas of the design while keeping others glossy. This creates a high-contrast, tactile experience that enhances the consumer’s perception of your brand’s quality.

4. Is the Epoxy inner coating safe for all types of beverages?

Our Epoxy liners are industry-standard and fully compliant with global food-safety regulations. They are designed to be inert, meaning they won’t react with the acidity of sodas or the delicate pH of craft beers. For specific “clean label” or organic requirements, we also offer alternative BPA-NI (Non-Intent) coating options.

5. How do “Axial Load” and “Buckling Pressure” affect my shipping costs?

A high Axial Load (1KN min) means the cans can be stacked higher on pallets without the bottom layer collapsing, which optimizes shipping container space. High Buckling Pressure (610 KPa min) ensures the cans won’t burst during ocean freight or high-altitude transport, significantly reducing “landed cost” losses due to damage.
