Engineered for seamless packaging lines in Hamburg, built with premium materials for food-grade safety standards.
Hamburg, serving as the logistics gateway of Northern Europe through the Port of Hamburg (Hafen Hamburg), is undergoing a dramatic shift in packaging paradigms. The regional demand for intelligent food-grade sealing machinery is driven by twin forces: high labor costs in Germany and strict EU directives concerning product safety and plastic circularity.
Traditional canning technologies are giving way to agile, small-to-medium footprint sealing solutions. Craft breweries in Altona, cold-brew coffee makers in Speicherstadt, and botanical beverage startups in Sternschanze require highly accurate, food-safe hermetic sealing for both aluminum cans and modern PET food-grade containers. Our specialized can sealing systems cater specifically to this demand, bridging the gap between local artisan quality and industrial-grade reliability.
With Germany's strict packaging tax frameworks and the mandatory deposit system (Dosenpfand) governing beverage retail, having a sealing operation that ensures exact double seam tolerances and zero material contamination is essential for both regulatory compliance and financial viability.
Highly durable, food-grade PET cans and aluminum lid combinations optimized for seamless automated sealing lines in Hamburg's dynamic food industry.
Established in 2021, Shanghai COPAK Industry Co., Ltd. maintains a high-efficiency sales and engineering office in Shanghai, supported by a specialized production facility in Guangdong Province. As a leading manufacturer and exporter, we specialize in high-quality PET cups, PET cans, and intelligent sealing machines designed for automated production lines.
Our commitment to continuous technical innovation enables us to serve clients across key global distribution hubs, including Hamburg, Germany. By offering structural designs ranging from 1oz to 32oz capacities, COPAK satisfies strict European safety expectations (LFGB food contact certification, CE machine directives).
With an export framework engineered to handle shipping to the Port of Hamburg seamlessly, we ensure German businesses obtain factory-direct pricing without sacrificing customer service or technical support. We act as a strategic partner, offering tailor-made tooling, custom printing, and mechanical integration support for all of our packaging products.
Achieving a reliable seal on PET (Polyethylene Terephthalate) cans presents unique physical engineering challenges compared to standard tinplate or aluminum cans. Because plastic is semi-flexible, traditional seaming rollers will deform the neck if the tooling is not designed to absorb structural stresses correctly. Our intelligent can seaming equipment uses a non-rotary seaming system that secures the can body while the dual seaming rollers trace the perimeter to form a perfect double seam.
This engineering method prevents centrifugal forces from spilling liquids, making it ideal for the high-end beverage industry, local fresh juice bars, and craft soda brands in Hamburg. Below are the key structural components of our seaming process:
The can remains stationary throughout the seaming cycle. This prevents product splash-out and guarantees consistent double seam geometry across different filling volumes.
Custom-milled chucks sit precisely inside the recessed lid profile (aluminum EOE or SOT). This setup distributes seaming pressures evenly, reducing micro-fissures in PET containers.
PLC units allow real-time adjustments of seaming parameters, rotation speeds, and dwell times to suit variable plastic wall thicknesses.
Operating in the German market requires strict adherence to environmental regulations. The German Packaging Act (VerpackG) enforces strict quotas on plastic recycling and registration with the LUCID packaging register. COPAK supports these green initiatives by offering 100% recyclable PET cans and RPET (recycled PET) solutions that fit perfectly within the European circular economy.
Key local application scenarios include:
As factories in Germany move toward Industry 4.0 standards, seaming machinery is evolving past simple mechanical links. Our upcoming product lines incorporate IoT sensors to monitor roller wear, seaming pressure, and motor torque on the fly. This preventive maintenance model reduces downtime by notifying operators when rollers need calibration.
Our smart touch-screen interfaces support multi-language operations (including German) and allow local engineers to quickly select pre-programmed profiles for 250ml, 330ml, 500ml, and 12oz/16oz can formats, minimizing downtime between product batches.

COPAK's PET containers are manufactured from 100% recyclable PET (Polyethylene Terephthalate). Under Germany's VerpackG, packaging materials must be registered with the LUCID database and licensed via a dual system (Duales System Deutschland). Because our PET is highly clean and structurally uniform, it meets the strict requirements for material recovery, minimizing license fees for local distributors.
Rotary systems spin the can during the seaming cycle. This motion can cause liquids to spill out of the open container, leading to inaccurate fill volumes and sticky residues that compromise the seal. Non-rotary systems keep the can stationary while the seaming head moves around it, preventing spills and protecting product freshness.
Yes, our smart sealing machines can process both SOT and RPT lids. The seaming chuck must match the exact dimensions of the lid profile (such as 202# diameter). Changing the seaming chuck for different lid styles is straightforward and takes less than 15 minutes, allowing you to run multiple profiles on a single machine.
We support our European customers with comprehensive online diagnostics, video setup guides, and detailed replacement manuals. Critical wear parts, including seaming rollers, chucks, and drive belts, are shipped via express courier to Hamburg to minimize production downtime.
