Step-by-Step Production Flow: Technical Diagram

Figure 3: Laminating & Spout Insertion—Core steps in liquid spout bags wholesale manufacturing

Material Preparation (Raw Film Selection):
- High-grade PET/AL/PE or PET/NY/PE multi-layered films procured — ensuring barrier and durability standards.
- Brands demand films certified under ISO 9001:2015 and FDA/SGS-tested for food safety.
Printing (Gravure/Flexo):
- Up to 10-color HD gravure print, tight registration (±0.1mm deviation), for vivid graphics, critical for printing coffee bags.
- In-line color density inspection and solvent residue tests performed.
Lamination:
- Solventless lamination using precise tension control, forming structures like PET/AL/PE, for both chemical inertness and puncture resistance.
- Cure time per ISO/ASTM D882-18 standard: 48–72 hours.
CNC-Precision Pouch Forming:
- Pouches are cut and shaped with CNC-guided machinery for edge finishing, minimizing leak points.
- Real-time testing for pouch integrity (ASTM F1921).
Spout Injection & Heat-Sealing:
- Insertion of branded spouts (various diameters), followed by ultrasonic or heat fusion sealing.
- Pull test, pressure retentivity tested, yields >40N/15mm (per F88 method).
Quality Control & Packaging:
- 100% inline QC—leak testing, weight deviation limits, visual inspection according to ANSI Z1.4.
- Bags packed in aseptic, anti-static wraps for export.
