The company was incorporated in 1964 as a Private Limited Company, with the main objective to set up an industrial undertaking for manufacturing of juices, squashes, sherbets, jams, pickles and preserves from fruits and vegetables. Shezan International Limited was conceived as a joint venture by the Shahnawaz Group of Pakistan and Alliance Industrial Development Corporation of U.S.A. The agricultural background of the Pakistani sponsors induced them to establish this agro-based industry. Taking advantage of abundance of fruits available in Pakistan and the advanced technology provided by the American partners, Shezan became a pioneer in the field of converting fruits into pulps, concentrates and juices.

Today Shezan is the largest food processing unit having developed and installed the capacity to meet the country's local as well as export needs. In 1971, Shahnawaz group purchased all the shares of Alliance Industrial Development Corporation. The company has since shown sustained growth in both domestic and export fields. In 1980-1981 a separate unit was installed in Karachi which now caters for Karachi, Sind and export demand. A new bottle filling plant was set in 1983 in the Lahore unit, increasing the capacity five fold.

An independent Tetra Brik plant was commissioned in 1987 making the unit leading manufacturers with the comprehensive range of production in the fruit processing field in Pakistan. In the year 1990 it was decided to install a juice factory at the Hattar industrial estate in North West Frontier Province of Pakistan. In order to take advantage of the government incentive new wholly owned subsidiary of Shezan International Limited was incorporated as Hattar Fruit Products Limited which was later merged into the parent company. Complete bottling plant locally manufactured along with four lines of Tetra Pak were installed, three are filling 250 ml juices and one line is for 1000 ml packs.

In all respects the subsidiary is now a complete unit and is manufacturing the complete range of Shezan products except for pickles and canned products.
