In 2008, Zengran Packaging launched the first fully automatic secondary packaging machine for Procter & Gamble, a Fortune 500 daily chemical giant, which automatically packaged small bags of laundry detergent into PP woven bags, thus creating a new era of fully automatic secondary packaging of small bags into large bags. After more than ten years of development, the fully automatic secondary packaging machines manufactured by Zhengyuan have been widely used in daily chemical, seed, sugar and other industries, with customers in China, Indonesia, Malaysia, Thailand, Europe and the United States, and are widely favored by users in domestic and foreign markets.

The demand for packaging automation has shown explosive growth. The traditional manual packaging method of small bags into large bags has been difficult to meet the requirements of production capacity and product quality and safety. More and more customers are turning their attention to fully automatic secondary packaging machines to achieve the goals of solving labor shortages, improving packaging appearance, controlling the packaging process, and improving packaging quality.
