Core Manufacturing Technology & Insulation Performance
Double-Wall Vacuum Insulation
Engineered with an advanced dual-wall stainless steel structure that creates an airtight vacuum barrier, effectively blocking thermal conduction and convection to lock in temperatures.
Copper-Plated Thermal Barrier
The outer wall of the inner tank is coated with a microscopic copper layer, reflecting thermal radiation to boost heat and cold retention by an additional 15% to 20%.
Seamless Inner Tank Technology
Utilizes high-precision stretch forming and seamless welding to ensure a smooth, crevice-free interior that prevents bacterial growth, corrosion, and unpleasant odors.

Raw Material & Rigorous Factory Testing Protocols
Premium 18/8 & 316 Stainless Steel: 100% rust-resistant, BPA-free, and metallic-taste-free food-grade steel that eliminates chemical leaching.
Quantified Thermal Retention: Tested at room temperature (20℃± 5℃). For our 500ml standard model, initial 95℃ boiling water stays above 55℃ after 12 hours.
100% Vacuum Integrity Screening: Every single insulated jar passes through an automated infrared vacuum detection line, guaranteeing a vacuum defect rate of less than 0.1%.
Online Pneumatic Leak-Proof Test: 100% online air-pressure testing to ensure absolute zero liquid leakage before assembly packaging.
Salt Spray Corrosion Test: Exterior powder coatings and stainless steel bodies endure rigorous salt spray environments to prevent peeling and rust.
Uncompromising Safety and Regulatory Compliance

18/8 (304) and 316 stainless steel jars tested against FDA 21 CFR and (EC) No 1935/2004 standards, guaranteeing zero heavy-metal migration.
