Excellent Heat Retention Food Jar

The Excellent Heat Retention Food Jar is a dual-chamber insulated container with a 1.1L total capacity, designed for maintaining food temperatures during transport. The body, lid, and bottom are constructed from polypropylene (PP) plastic, with a removable inner glass liner produced using Japanese vacuum insulation technology. The jar includes two stackable food trays for separating meals, and a wide-mouth opening for easy filling and cleaning.

The inner glass liner is thick-walled and borosilicate-grade, with a vacuum-sealed space between double walls to minimize heat transfer. Heat retention performance is verified to maintain temperatures at or above 78°C after six hours when filled with boiling water. The outer PP shell provides impact resistance and thermal insulation, while the non-slip base prevents sliding. Color and pattern options are customizable, and the Rang Dong logo is laser-etched onto the lid.

This product is commonly purchased by school canteen operators, meal delivery services, and healthcare providers needing safe, temperature-controlled food transport. Buyers typically order in quantities of 500 to 5,000 units. The jar is designed for repeated use and is dishwasher-safe. Packaging is bulk carton with internal dividers. Trade terms are not specified but are typically offered as FOB Haiphong or CIF. Minimum order quantity is not stated and must be confirmed with the supplier.
