The paper sack industry in Iran is a relatively new industry, with the first paper sack factory being established in the early 1990s. The industry has grown rapidly in recent years, due to the increasing demand for paper sacks from the packaging industry. The majority of paper sack producers in Iran produce paper sacks for the food industry. However, there is a growing demand for paper sacks from other industries such as the pharmaceutical and chemical industries. The paper sack industry in Iran is highly competitive, with a large number of small and medium-sized enterprises. The industry is also facing challenges such as the high cost of raw materials, the lack of skilled labor, and the need for new technology.
