1. What is an side gusset bag?
A side gusset bag is a type of flexible packaging pouch characterized by expandable folds (gussets) on its left and right sides. These gussets allow the bag to lie flat when empty but expand significantly to hold more volume when filled.
2.Three core advantages directly hit the pain points
Three-dimensional expansion, cost reduction and efficiency improvement
Double-sided accordion pleats are automatically expanded, and the capacity is increased by 15%+ (compared with flat bags of the same size)
Flat storage → three-dimensional loading, significantly reducing logistics and storage costs
Self-standing and stable, strengthening the brand
Square bottom automatically stands, and shelf display is more stable
Flat double-sided provides high-definition printing space to improve product recognition
Full coverage of scenarios
✔️ Food (snacks/pet food) ✔️ Daily chemicals (laundry powder/cat litter)
