Precision Film Slitting & Pouch Making
Dedicated equipment and proven processes turn different packaging requirements into consistent, reliable flexible packaging products.
01
Precision Slitting for Accurate Roll Dimensions
Our slitting equipment controls roll dimensions to packaging specifications, achieving width tolerances as tight as ±0.3 mm. Clean cuts provide a consistent foundation for subsequent bag making.
02
Multiple Bag-making Machines for Diverse Formats
Our 26 bag-making machines produce mailer bags, stand up pouches, flat bottom pouches, three side seal pouches, center seal pouches, zipper pouches and shaped pouches for different product applications.
03
Flexible Bag Making for Custom Requirements
We adjust dimensions, structures and functional features to suit each product and its use, reliably bringing both standard and custom packaging into production.
Packaging Quality Control at Every Stage
Five quality control stages and batch traceability maintain consistent packaging quality across every batch.
Incoming Material Inspection (IQC)
Supplier reviews and incoming inspections ensure all production materials meet the required performance standards.
First-article Approval
Before full production, we confirm product specifications, process parameters and packaging results to reduce variations across the batch.
In-process Inspection (IPQC)
Continuous monitoring of key production stages helps identify and correct deviations promptly.
Finished Product Inspection (FQC)
We check finished products to verify that dimensions, appearance and performance meet order specifications.
Pre-shipment Inspection (OQC)
Final checks before delivery ensure customers receive consistent, reliable packaging.
Batch Traceability
Production records and retained samples enable quality tracking throughout the manufacturing process.
Consistent Production for Long-term Partnerships
Our production network and flexible manufacturing management accommodate different order volumes while maintaining dependable lead times.
