Brief Introduction to Stand-Up Zippered PE Bags 

• Upright stiffness is increased by 40%-60% : The reinforced bottom structure supports the weight of contents, preventing tipping on shelves, and space utilization is 30% higher than that of flat-laid bags;
• Moisture-proof sealing performance is enhanced by 50%-70% : The tight-fitting zipper reduces moisture transmission rate, lowering the clumping rate of dry goods by over 90%—for example, the shelf life of coffee beans extends from 3 months to 5 months;
• Load-bearing capacity is improved by 30%-50% : The stand-up structure distributes pressure on the bag body, reducing the side tearing rate by 85% compared to flat-mouth bags when filled with 5-10kg items;
• Printed display effect is boosted by 20%-30% : The flat, wrinkle-free surface of the stand-up bag fully presents brand logos and product information, with visual recognition 40% higher than that of regular bags.

1. Shelf-friendliness : Upright placement reduces stacking space, and the front of the bag faces upward for easy consumer identification—unlike regular flat-mouth bags, which need to be laid flat or stacked with poor display effect;
2. Convenience of repeated sealing : The zipper design requires no auxiliary tools and can be opened/closed with one hand, solving the trouble of regular bags needing clips for sealing after opening, suitable for home, outdoor, and other access scenarios;
3. Multi-functional customizability : It can be additionally customized with transparent viewing windows (to check the state of contents) or one-way exhaust valves (e.g., for moisture-proof exhaust in coffee bags)—functions that regular PE bags rarely combine, making it suitable for high-end retail packaging scenarios.
