Folded Side Gusseted Bag

Brief Introduction to Side-Folded PE Bags  Side-Folded PE Bags use High-Density Polyethylene (HDPE)/Low-Density Polyethylene (LDPE) as the base material. Their core process involves folding the edge on both sides of the bag and reinforcing it with heat sealing, forming a double-layer side structure. This design balances loading strength and usability, making the bags widely applicable to medium-to-large capacity, stretch-resistant scenarios—such as 2-10kg rice/grains, hardware parts, large-size daily chemical packages (laundry detergent/washing powder), and fresh produce turnover. Compared with regular flat-mouth PE bags, their core performance is significantly improved: Load-bearing capacity is increased by 30%-50%: The double-layer folded sides can distribute tension, reducing the side tearing rate by more than 90% when the bag is filled with heavy items; Stiffness is enhanced by 40%-60%: The bag has stronger upright stability, avoiding collapse during warehouse stacking and saving…
