What are the advantages of the latest technology - nano polishing?
Zhejiang Gint Vacuum Flask Technology Co., Ltd.

Plasma Nano Photo-Thermal (PLNP)multi-layer nanocoating technologies, marking a decisive shift away from conventional electrolytic processes in drinkware production.
The innovation, debuted at the 2025 Shanghai Housewares Show, introduces a chemical-free, water-based nano-polishing system that forms a dense, oxide-based protective layer in under two minutes – slashing processing time by 80% compared to traditional methods.
Eco-Performance Redefined
electricity, water, and non-toxic salts to generate a plasma-induced nanofilm. Independent lab tests confirm that the PLNP-treated surfaces reduce heavy metal ion leakage by 98%, effectively eliminating risks linked to nickel or chromium leaching.
"We're not just altering surfaces – we're building safer, longer-lasting products from the molecular level," said Dr. Li Wei, GINT's Head of Material Science. "This is a clean-tech response to global concerns around drinkware safety and waste."

Self-sterilizing surfaces that deactivate pathogens like E. coli
Hydrophobic barriers mimicking lotus-leaf microstructures to repel liquids and stains
UV-blocking and anti-fouling properties for outdoor and daily-use products
low-temperature physical vapor deposition (PVD), preserving material integrity while enhancing surface hardness by over 160%.
With tightening international regulations – including Europe's upcoming Chemical Restriction Roadmap and North America's Proposition 65 – brands are under mounting pressure to adopt cleaner production methods. GINT's nano-polishing platform enables compliance without compromising cost or scalability.
40% fewer product returns due to corrosion or coating failure, alongside strengthened consumer trust in hygiene claims.
