Behind Every Bag
Our Production & QC Process
01.
Film Blowing & Printing
Our advanced film blowing technology ensures uniform thickness and high strength, while our high‑precision printing delivers sharp, vibrant graphics with accurate color registration. These are followed by meticulous sealing and cutting, carried out by experienced technicians, to guarantee reliable performance and long‑lasting use.
02.
Cutting & Sealing
From flat bags and vest bags to zipper bags and gusseted designs, our cutting and sealing lines are configured to handle a wide variety of bag styles. We ensure tight seal integrity, accurate sizing to ±1mm, and smooth finish, so every bag performs reliably in your application – whether for medical, pet, or food packaging.
03.
QC & Packaging
Before packing, every batch undergoes a final visual inspection to ensure dimensions, printing, and sealing meet your specifications. We then manually sort, count, and pack the bags into durable export cartons, with customized labeling and packing lists available. This thorough hand-packing process guarantees that your order is well-organized, traceable, and ready for smooth customs clearance.
