Bengal Glass has observed a steady growth in demand for glass bottles and shells and has periodically expanded its production capacity since going into production in 1975. The plant in Demra is currently the single largest installed facility for amber glass in Bangladesh. It currently has a capacity of 155 MT per day and manufactures USP Type III amber bottles for the pharmaceutical industry as well as lamp shells for the lighting industry.

With the two amber glass furnaces, the company has the capacity to produce 400 million USP Type III amber bottles per year of various sizes (15 ml to 750 ml) for packaging of allopathic, homeopathic, personal care, agricultural and veterinarian products. The third furnace produces 133 million Glass Lamp Shells per year of various designs (45 mm to 75 mm diameter) for the incandescent lighting industry. The furnaces run on natural gas with diesel oil as backup.

The company also started development for producing Flint (Clear) Glass bottles for packaging of food and beverage products and started production in 2013.

All the furnaces are equipped with control rooms, which are used to manufacture bottles all around the year with 94% pack-to-melt efficiency. A captive power plant provides uninterrupted power supply to the facility. The plant has the latest machines and equipment sourced from reputed suppliers. For example, the Furnaces are designed by SORG, Batch House from Zippe, IS Machines from Emhart, Rotary blowing machines from Olivotto, and Lehrs from Pennekamp.

The facility is supported by mould design and manufacturing workshops.

The company's daily operations are controlled through SAP ERP and employees are connected through local area network as well as wide area network with high-speed radio-link.
