The Complete Production Workflow of Custom Flexible Packaging Bags: From Printing to Finished Pouches

Many brand buyers want to cooperate with reliable packaging manufacturers with standardized production lines and strict quality control. Understanding the whole production process helps you judge whether a supplier can deliver stable, export-qualified flexible packaging.As a professional flexible packaging manufacturer, we produce a full range of custom printed packaging for global merchants, covering [stand up pouches], [8 side seal flat bottom bags], [three side sealed sachet bags], [leak-proof spout pouches], [special-shaped packaging bags] and [food-grade composite roll film]. Our workshop is equipped with complete sets of production equipment and standardized testing procedures. Let’s walk through our packaging manufacturing workflow step by step.

Printing Process

Custom artwork is printed onto packaging film with precise color control. Consistent printing effect is the foundation of attractive brand packaging. After printing, the film will be delivered to the lamination workshop.

Solvent-Free Lamination

We adopt solvent-free composite machines to laminate different film materials together. Compared with traditional dry lamination, solvent-free lamination brings lower residual solvent, which fully meets food-safe requirements for exported food and cosmetic packaging.

Mature Curing Room

After lamination, composite film enters the curing room for constant-temperature aging treatment. Sufficient curing stabilizes composite strength, effectively preventing delamination, bubbling and peeling issues during long-term storage and transportation.

Slitting Process

Cured large roll materials are processed by professional slitting machines. We cut wide master rolls into narrow roll stock according to customer specifications. Neat cutting edges avoid leakage risks for automatic filling production lines.Customers with automatic packing machines can purchase finished [food-grade composite roll film] directly from us.

Bag Making Production

Multiple sets of automatic bag-making machines support the production of various pouch styles. The equipment can fabricate flat [three side sealed sachet bags], zipper [stand up pouches], bottom-support [8 side seal flat bottom bags], liquid [leak-proof spout pouches] and unique [special-shaped packaging bags] in different sizes.

Strict Quality Inspection

Every batch undergoes systematic inspection before shipment. Our inspection procedures cover thickness testing, sealing strength test, leakage testing, printing color checking and barrier performance verification. Unqualified semi-finished and finished products will be eliminated strictly to guarantee consistent quality.
