Explore our high-performance vacuum-insulated lunch box cups and tumblers compliant with European directives.
The global commercial landscape for thermal food containers, lunch box cups, and insulated hydration vessels is undergoing a massive transformation driven by strict regulatory imperatives, consumer sustainability shifts, and advanced metallurgical standards. As global buyers navigate complex international compliance protocols, partnering with a certified manufacturer becomes a fundamental business requirement.
CE certification (Conformité Européenne) represents a non-negotiable benchmark for compliance within the European Economic Area (EEA), ensuring that food contact materials (FCM), thermal performance, heavy metal leaching resistance, and mechanical durability meet stringent European Directives. Under regulation (EC) No 1935/2004 and EU No 10/2011, insulated lunch box cups must undergo strict analytical testing to confirm zero toxic chemical migration under high-temperature thermal loads.
Uncompromising structural integrity through advanced vacuum extraction and chemical passivation.
Our double-walled lunch box cups utilize a high-density vacuum air gap evacuated at temperatures exceeding 500°C down to 10-3 Pa pressure. This eliminates heat transfer via conduction and convection, locking temperature inside.
To block infrared thermal radiation, an ultra-thin microwave copper lining is electro-deposited onto the outer surface of the inner stainless steel wall. This reflects thermal radiation back into the food container.
Utilizing high-grade SUS304 and medical-grade SUS316 stainless steel with 18% chromium and 8% nickel content. This composition delivers extraordinary resistance against acidic food corrosion and impact deformation.
