The global can sealing market is projected to reach $5.2 billion by 2028. As the beverage industry shifts toward PET portability, high-speed, precision sealing machines have become the backbone of modern bottling lines.
Advanced polymers and BPA-free PET materials are revolutionizing storage. Our custom sealers ensure a hermetic oxygen barrier, extending the shelf life of cold-brew coffee and carbonated beverages by up to 40%.
With global plastic bans, the "Easy-Open" PET can represents a middle ground: 100% recyclable materials combined with the convenience of traditional aluminum canning technology.
The industrial can sealing sector is no longer just about closure; it is about brand integrity. For exporters and manufacturers, the challenge lies in maintaining seam consistency across varying atmospheric pressures during global transit. As a leading Custom Can Sealer Service provider, we address the "micro-leakage" phenomenon that often plagues lower-tier packaging, ensuring that your product arrives in New York or London with the same carbonation levels it had in the factory.
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.

Precision sealing prevents nitrogen escape, ensuring the "cascade effect" remains intact for consumers.
Tamper-evident easy-open lids allow bars to offer high-end takeaway experiences without compromising flavor.
Transparent PET cans showcase layered desserts while the airtight seal maintains moisture levels.
Designed for brands requiring mass-produced, branded containers that withstand cross-continental shipping.
Q: What is the primary cause of seam failure in PET cans?
A: Most failures occur due to incorrect roller pressure calibration. Our custom sealers utilize digital pressure gauges to ensure consistency within ±0.05mm across 10,000+ units.
Q: Can PET cans handle carbonation for long periods?
A: Yes, specifically our OEM PET cans for carbonated drinks are tested to withstand internal pressures of up to 90 PSI, similar to traditional aluminum cans.
Q: How do you support international exporters?
A: We provide full documentation (CE, FDA, SGS) and modular machine designs that are easily maintained by local staff, reducing downtime for global partners.
