Our flat bottom bag with zipper delivers exactly that. Backed by 25 years of manufacturing expertise at Guoshengli Packaging, these pouches feature a reinforced five-panel design that provides 12–15% more volume than traditional stand-up pouches. With multi-layer barrier films achieving oxygen transmission rates below 0.5g/m²/24h, advanced zipper closure systems, and up to 11-color rotogravure printing across five printable surfaces, you get enterprise-level performance with fast turnaround times of 15–20 days for custom orders.



You need packaging that works as hard as your product. These bags solve real problems.
Stable Shelf Presence
The box-shaped base eliminates tipping issues. Your product stands confidently on retail shelves. The reinforced flat bottom provides a solid footprint that maximizes space efficiency.
Superior Barrier Protection
Multiple laminated layers block oxygen, moisture, and light. Your product stays fresh longer. We engineer each structure to match your specific shelf-life requirements.
Five Printable Surfaces
Front, back, bottom, and two side gussets give you maximum branding space. Tell your complete product story with high-impact visuals using our 11-color printing technology.
Convenient Zipper Closure
Resealable functionality keeps contents fresh after opening. We offer various options: press-to-close, pocket zipper, or slider systems. Each maintains product integrity through multiple uses.

We construct each bag using high-performance laminations:
· PET layers for structural strength and clarity
· VMPET or ALU for superior barrier protection
· NY (Nylon/BOPA) for puncture resistance
· PE inner layers for heat sealing and food contact safety
This combination achieves water vapor transmission rates below industry standards while maintaining flexibility.
The eight-corner seal design provides vertical rigidity you can't get from traditional pouches. This engineering prevents leaning and ensures consistent presentation throughout the supply chain.
