In today’s fast-paced lifestyle, insulated flasks have become essential for maintaining the temperature of beverages, whether hot or cold, for extended periods. These flasks feature a sophisticated dual-layer design: an inner layer that holds the liquid and an outer layer that encases the inner layer. The space between these layers is filled with a high-quality food-grade insulating material that prevents heat transfer through conduction and convection.

The Indian Government's recent decision to mandate BIS certification for insulated flasks marks a significant advancement in product quality, safety, and consumer satisfaction.

Indian Standard IS 17790 : 2022

Indian Standard IS 17790 sets forth the requirements for domestic insulated stainless steel flasks, ensuring they effectively maintain the temperature of hot and cold liquids intended for consumption. This standard outlines the necessary materials and construction practices to guarantee the performance and safety of these essential products.
