Good Thermal Retentive Big Size Vacuum Flask

The Good Thermal Retentive Big Size Vacuum Flask offered by Rang Dong Light Source & Vacuum Flask Joint Stock Company is a 2 L insulated container designed for prolonged temperature maintenance. It retains heat of at least 78 °C after six hours of continuous use, meeting the performance level required for commercial catering. The flask body, lid, stopper and bottom are fabricated from polypropylene (PP) plastic, a material known for its durability and food‑grade safety. The included glass refill is produced with Japanese technology, providing an additional barrier that enhances heat retention.

The PP construction allows for colour and pattern customization, enabling branding or visual alignment with client specifications. The lid doubles as a drinking cup, a feature commonly valued in field service and outdoor catering environments. In the vacuum flask market, double‑wall vacuum insulation and detachable bottoms are standard design elements that facilitate cleaning and improve skid resistance.

The supplier accepts OEM orders and can accommodate logo imprinting, making it suitable for private‑label projects. Trade terms such as minimum order quantity, incoterms and payment conditions are not disclosed in the listing and should be confirmed directly with the company.
