In the contemporary beverage landscape, the hand crank can seamer has transitioned from a rustic utility to a precision-engineered necessity for small-batch producers, R&D labs, and high-end craft beverage curators. As an OEM Hand Crank Can Seamer Manufacturer, Shanghai COPAK Industry Co., Ltd. integrates decades of mechanical expertise with modern material science to deliver hermetic sealing solutions that define industry standards.
Our manual seamers utilize a double-seam mechanism designed to handle PET cans and aluminum lids with micrometer accuracy, ensuring zero carbonation loss and extended shelf life.
Meeting the rigorous demands of enterprises in North America, Europe, and Southeast Asia, our equipment is certified for food-grade safety and operational longevity.
Hand-operated machinery reduces the carbon footprint of production lines, making it the ideal choice for eco-conscious startups and remote-area artisanal shops.
At Shanghai COPAK Industry Co., Ltd., we bridge the gap between traditional craftsmanship and the China Factory 4.0 paradigm. Our production facility in Guangdong Province acts as the engine of our innovation, leveraging automated CNC machining for parts production while maintaining the human-centric quality control that manual machines require.
Ideal for sealing small batches of cold brew, kombucha, and craft sodas without the capital expense of fully automatic lines.
A must-have for testing seal integrity and shelf-stability in controlled laboratory environments before mass production.
Provide a unique experience by canning fresh juices or cocktails on-site, ensuring hygiene and a "wow" factor for guests.
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.

Automatic vs. Manual Sealing
Choosing the right technology for your scale.
Yes. The fundamental "Double Seam" principle remains identical. Our manual machines are calibrated to apply the exact pressure required to interlock the can flange and the lid curl, creating a hermetic seal. The primary difference is throughput, not quality.
Our seamers are optimized for PET cans and aluminum Easy-Open-Ends (EOE). We offer custom chucks to accommodate various diameters, including the standard 202# (52mm) and other custom sizes up to 32oz capacities.
As a senior OEM manufacturer, we provide end-to-end customization. This includes custom logo printing on cans, specific color coatings for the seamer body, and engineering adjustments to suit unique container heights or shapes.
Maintenance is minimal. Regular lubrication of the rotating bearings and periodic inspection of the seaming rollers for wear are sufficient to ensure years of reliable operation in a commercial environment.
