Engineered for high-hermeticity and shelf-life extension
Modern enterprises are shifting toward integrated packaging ecosystems. The demand for Seamer Machines is no longer just about the hardware; it's about the synergy between PET clarity and aluminum seal integrity. Global buyers now prioritize suppliers who offer Turnkey Solutions—where the machine, the PET container, and the easy-open end (EOE) are synchronized for zero-defect production.
From Cold-Brew Coffee to Ready-to-Drink (RTD) cocktails, the "Can-fication" of beverages is driving a macro-economic shift. We provide smart seaming solutions that adapt to different PET wall thicknesses, ensuring that even under variable temperatures, the double-seam remains intact. This is critical for Cold Chain logistics where pressure differentials can cause leaks in inferior packaging.
Navigating global regulations (FDA, EFSA, CE) requires more than just a certificate. Our seamer machines are built with Food-Grade Stainless Steel (SUS304/316) and offer localized compliance support. For the PET components, we utilize BPA-free materials and offer RPET (Recycled PET) options to meet the rigorous Sustainability Goals (SDGs) of Fortune 500 companies.

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.
Leading the 4th Industrial Revolution in Beverage Packaging
Implementation of Real-time Vision Inspection Systems within our Seamer Machines. AI algorithms will detect micron-level seam defects, automatically rejecting non-compliant cans without halting the production line.
Cloud-connected seaming stations that provide Predictive Analytics. Factories will receive alerts before a mechanical failure occurs, reducing downtime by up to 40% through remote diagnostic capabilities.
Development of machines optimized for 100% Mono-material Packaging. Our goal is to enable seamless transitions between PET, Bio-plastics, and Aluminum, fostering a truly circular industrial loop.
Technical insights for procurement and engineering teams
Unlike metal-to-metal seaming, PET seaming requires precise temperature and pressure control to prevent the PET flange from cracking while ensuring the aluminum lid curls correctly. Our machines feature Soft-Touch Seaming Rolls specifically designed for the ductile properties of PET.
Shelf-life is a function of the Oxygen Transmission Rate (OTR) and the seam's hermeticity. By optimizing the "Double Seam" geometry, we achieve an airtight seal that, when combined with our high-barrier PET resins, rivals traditional metal cans for many RTD beverages.
Yes. We provide comprehensive Global Technical Support, including remote video commissioning, multilingual operational manuals, and a modular spare-parts system that ensures critical components are available in major logistics hubs.
Our Universal Smart Seamers come with quick-change modular heads. A technician can switch between a standard 202 SOT lid and a wide-mouth deli lid in under 15 minutes, allowing for maximum production flexibility.
