How can fertilizer manufacturers choose reliable packaging? In-depth Analysis of Selection Criteria from QiChen Packaging

With the acceleration of agricultural modernization, liquid fertilizers have gradually become the mainstream choice in the agricultural supplies industry due to their advantages such as fast absorption, excellent fertilizer efficiency, and environmental friendliness. However, the packaging of liquid fertilizers has always been a pain point in the industry: traditional hard packaging is costly, difficult to transport, and has insufficient stability, making it difficult to meet the demands of large-scale production and modern agriculture. As a globally trusted liquid flexible packaging partner, Qichen Packaging, based on over 20 years of industry experience, innovatively proposed four core elements of liquid fertilizer flexible packaging to address the problem of packaging stability from the root and create standardized and professional solutions for the industry. 

Introduction: The industry pain points of liquid fertilizer packaging 

At present, the domestic liquid fertilizer market is in a period of rapid growth, with an annual growth rate of 20%-30% and sales volume of about 10 million tons in 2024. But the packaging of liquid fertilizers has become a major bottleneck restricting the development of the industry: 

• High cost: Traditional 20kg plastic bucket packaging costs about 12-15 yuan, accounting for more than 30% of the total cost of liquid fertilizer
