Established in 2021, Shanghai COPAK Industry Co., Ltd. maintains a sales office in Shanghai and an associated factory in Guangdong Province. As a professional supplier of eco-friendly food and beverage packaging solutions, our product portfolio includes PET cups, PET cans, and sealing machines, among other related items.
Committed to staying ahead of market trends through continuous innovation, COPAK delivers high-quality yet cost-effective packaging solutions. Our product range covers PET cups and cans in diverse shapes and capacities—from 1oz to 32oz—available in both plain finishes and custom printed designs.
In the rapidly evolving landscape of the global beverage industry, the demand for "on-demand" packaging solutions has reached an all-time high. Procurement officers from North America to Southeast Asia are increasingly prioritizing the Cannular Semi Auto Pro Can Seamer due to its unique position at the intersection of affordability and industrial-grade precision.
Small-to-medium breweries and specialty beverage startups no longer need to rely on massive, multi-million dollar rotary seaming lines. The Cannular Pro allows for decentralized production, enabling brands to test markets with limited-run seasonal releases without high capital expenditure (CAPEX).
With the global shift toward circular economies, the ability to seam PET cans with aluminum Easy-Open Ends (EOE) has become a strategic advantage. Procurement teams are seeking manufacturers like COPAK who offer integrated solutions—both the containers and the machines—to ensure hermetic seal integrity and reduce oxygen ingress.
The "Semi-Auto Pro" designation signifies a reduction in human error. Unlike manual versions, the automated seaming cycle ensures consistent 1st and 2nd operation roller pressure, which is critical for meeting international food safety standards and shelf-life requirements.
Strategic Insight: The integration of a Cannular Semi Auto Pro into a production workflow is not just about "sealing a lid"—it is about ensuring the chemical and physical stability of the beverage inside. From craft beer carbonation levels to the delicate nitrogen infusion in cold brew coffee, the seamer is the final gatekeeper of quality.
For taprooms moving into retail, the Cannular Pro serves as the bridge. It offers a throughput that satisfies local distribution needs while maintaining the seam specifications required by commercial retailers.
Ready-to-Drink (RTD) cocktails and functional juices utilize PET cans for transparency and branding. Our technology ensures that the seam between the plastic neck and the metal lid is robust enough to withstand internal pressure and external logistics stress.
Venues are increasingly canning drinks on-site for "to-go" sales. The compact footprint and low noise levels of the Cannular Pro make it the ideal front-of-house or back-of-bar solution for high-end hospitality groups.
As a leading Cannular Semi Auto Pro Can Seamer manufacturer, COPAK is at the forefront of the next generation of packaging technology. Our R&D roadmap focuses on three core pillars: Precision, Intelligence, and Material Versatility.
Future iterations of the Pro series will include integrated sensors to monitor seaming torque and roller displacement in real-time, providing immediate feedback on seam quality and reducing the need for destructive testing.
We are developing rapid-changeover chucks that allow operators to switch between standard 202 ends, 200 ends, and specialty sizes in under 60 seconds, catering to the "High-Mix, Low-Volume" production trend.
Leveraging machine learning, our next-gen seamers will predict roller wear-and-tear based on cycle counts and pressure profiles, notifying users via a mobile app before a failure occurs.
COPAK understands that a machine is only as good as the support behind it. With our products distributed globally, we have established a robust framework for international compliance and localized technical assistance.
Our Cannular Semi Auto Pro units are engineered to meet CE, UL, and CSA standards, ensuring they can be legally and safely deployed in Europe, North America, and beyond. We provide localized voltage configurations (110V/220V) to match regional power grids.
With a dedicated factory in Guangdong and a global sales hub in Shanghai, we maintain a deep inventory of spare parts—rollers, chucks, and motors—ensuring that our clients' production lines never stay dark for long.

A: The Semi Auto Pro automates the seaming cycle. While the manual version requires the operator to manipulate a lever to engage the rollers, the Pro version uses an automated carriage. This ensures that the pressure and timing of the 1st and 2nd operations are identical for every can, resulting in much higher consistency and lower failure rates.
A: Yes. However, it is important to note that PET cans require a specific "visco-elastic" seaming profile. Our machines come with hardened rollers that can be fine-tuned to ensure a hermetic seal on both rigid aluminum and flexible PET containers without cracking the plastic flange.
A: We recommend a "tear-down" seam inspection every 5,000 cans or at the start of every major production run. Using a micrometer to check the seam thickness, width, and overlap ensures the machine stays within the "Green Zone" of safety specifications.
A: An experienced operator can comfortably seam 15 to 20 cans per minute. This makes it suitable for batches ranging from 100 to 2,000 units per day, common in craft brewing and boutique soft drink manufacturing.
A: Absolutely. All our Cannular machines come with a comprehensive 12-month warranty on core components. We provide video-based technical support, digital manuals, and have a global logistics network to dispatch replacement parts within 48-72 hours.
A: Yes, the machine is designed for versatility. By changing the top chuck and adjusting the table height, the Cannular Pro can handle 200, 202, and 206 end diameters across various heights from 100ml to 1000ml.
