Description
Product Overview
Custom printed side gusset flat bottom standup pouch is a heavy-duty flexible packaging solution designed for bulk dry goods and pet food, also widely known as custom printed flat bottom standup pouch for retail shelf display. The PET/VMPET/PE composite structure delivers excellent stiffness and barrier performance for large-volume packaging. The outer PET layer provides high rigidity and a premium printing surface for your custom brand artwork. The middle VMPET metallized layer blocks oxygen, moisture and UV light, preventing fat oxidation and mold growth in pet food. The inner PE layer ensures strong heat sealing for secure edge closure even under stacking pressure.
The side gusset design expands internal volume without sacrificing shelf stability, while the flat bottom structure allows the pouch to stand firmly on retail shelves and warehouse pallets. Our custom printed side gusset flat bottom standup pouch supports full-color gravure printing, making it the top packaging choice for pet food brands and bulk dry food suppliers.
