In the current global manufacturing landscape, the transition from single-use plastics to highly recyclable PET and aluminum containers has accelerated the demand for precision sealing technology. The "Dixie Double Seamer" style technology represents the gold standard for small to medium-sized production lines, providing airtight, leak-proof, and tamper-evident packaging.
Our custom double seamer solutions utilize a two-stage process: the first operation curls the lid flange around the body hook, and the second operation flattens the seam to ensure a hermetic seal. This level of mechanical precision is critical for the burgeoning RTD (Ready-To-Drink) coffee and craft beverage sectors.
As circular economy mandates tighten in the EU and North America, our PET can and double seamer pairings offer a lightweight, 100% recyclable alternative to traditional glass, reducing shipping carbon footprints by up to 35%.
Established in 2021, Shanghai COPAK Industry Co., Ltd. maintains a strategic sales office in Shanghai and a high-tech manufacturing facility in Guangdong Province. As a professional supplier of eco-friendly food and beverage packaging solutions, we specialize in PET cups, PET cans, and the sophisticated sealing machinery required to integrate them into your production flow.
Committed to staying ahead of market trends through continuous innovation, COPAK delivers high-quality yet cost-effective packaging solutions. Our range covers 1oz to 32oz capacities, available in both plain finishes and custom printed designs, serving as a long-term strategic partner for global beverage brands.
We don't just supply products; we engineer solutions. Our Dixie-style double seamers are customized for specific can diameters and material thicknesses, ensuring that whether you are sealing PET or Aluminum, the structural integrity of the seam remains uncompromised under pressure.
Focus on BPA-Free PET materials and FDA-compliant sealing standards. Our double seamers are designed for easy maintenance in craft brewery environments.
Emphasis on the "Green Deal" and recyclability. Our PET cans meet strict EU food safety standards and are compatible with existing recycling streams.
Support for high-throughput RTD tea and coffee production. We provide localized technical support and spare parts logistics from our regional hubs.
By 2026, COPAK aims to integrate AI-driven visual inspection modules into our double seamers, allowing for real-time seam analysis and rejection of faulty units without stopping the line.

Quality Assurance Testing
The seaming roller engages the lid, rolling it under the can flange. This determines the 'seam thickness' and 'seam gap'. A failure here leads to immediate leakage.
A second roller with a different profile compresses the previously formed seam. This metal-to-metal (or metal-to-PET) compression creates the gas-tight seal required for carbonated beverages.
PET reacts differently to heat and pressure than aluminum. COPAK's custom Dixie-style seamers use specialized titanium-coated rollers to prevent PET deformation during high-speed sealing.
