In the contemporary global beverage landscape, the 202 diameter (52.5mm) standard has emerged as the definitive benchmark for slim and sleek can designs. As a leading 202 Can Seamer Supplier, we recognize that the shift from traditional metal packaging to hybrid PET-Aluminum configurations requires a paradigm shift in sealing technology.
Macro-economically, the beverage industry is witnessing a CAGR of 6.5% in the PET canned segment. This growth is driven by the consumer's demand for transparency—being able to see the product's color and texture—while maintaining the shelf-life integrity provided by hermetic double-seaming.
Modern 202 seamers utilize servo-driven technology to ensure consistent torque and pressure, vital for PET's unique structural properties.
Our 202 can seamers employ a two-stage process. The first operation rolls the lid curl into the can flange; the second operation flattens the seam to create a gas-tight seal that withstands internal carbonation pressures.
Specialized tooling for PET-to-Aluminum bonding prevents stress cracking in the PET neck area, a common failure point in low-quality seamers.
Industry 4.0 ready. Our machines feature PLC controls and digital sensors that monitor seaming speed and pressure in real-time to minimize waste.
Advanced seaming heads ensure an Oxygen Transfer Rate (OTR) that meets the strictest standards for craft beer and sensitive fruit juices.
We provide more than just machinery; we provide integrated supply chain stability. For high-volume producers, our 202 can seamer services include line layout optimization and "Right-First-Time" manufacturing protocols.

Global Markets
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. As a long-term strategic partner and trusted supplier, we dedicate ourselves to designing and manufacturing reliable, premium-quality, and stylish PET cups and cans for our clients.
Navigating international regulations is complex. COPAK simplifies this through rigorous compliance standards. Our 202 can seamer technology and materials meet the following benchmarks:
We provide localized technical support including remote diagnostic services, readily available spare parts hubs in North America and Europe, and multi-lingual documentation. This ensures your production line never stays idle, maintaining high OEE (Overall Equipment Effectiveness) across your entire operation.
In the EU and US markets, material migration limits and machine safety directives are strictly enforced. Choosing a compliant supplier like COPAK mitigates legal risks and enhances brand trust.
The roadmap for 202 can seamer technology is inextricably linked to sustainability. RPET (Recycled PET) is no longer an option but a requirement. Our upcoming 2026 machine series is designed to handle the slightly different thermal and mechanical properties of high-percentage RPET, ensuring the same seal integrity as virgin materials.
Furthermore, AI-driven predictive maintenance is becoming standard. Our R&D department is currently integrating acoustic sensors that can detect "micro-flaws" in a seam based on the sound frequency of the sealing rollers, allowing for intervention before a leak occurs. This represents the pinnacle of "Zero Defect" manufacturing in the packaging world.

A 202 end refers to a standard diameter of 2.125 inches or 52.5mm. It is the most common size for slim cans and many standard beverage cans globally.
Yes, but it requires specific adjustments. While the seaming principle is the same, PET requires lower heat and more precise pressure control to avoid deforming the plastic flange. Our machines are built with modular chucks to handle both.
Absolutely. High-quality PET cans with a proper 202 double seam can withstand internal pressures up to 90 PSI, making them perfect for sodas, sparkling water, and craft beer.
All COPAK PET products are manufactured from virgin food-grade resin that is 100% BPA-free. We provide material certification and lab reports (SGS/FDA) with every wholesale order.
