2. Manufacturing Process of Eight-Sided Sealed Packaging Bag
Process Flow Diagram:
(Visually illustrated below with key nodes and arrows)
- Material Selection & Lamination: Multi-layer films (PET/AL/PE/NY) are chosen for tailored barrier properties. ISO 527-3/ASTM F1927 certified raw materials ensure high consistency.
- Flexo/Gravure Printing: Up to 10-color inline high-resolution print with FDA-compliant inks. Precision registration checked by AI-based inspection system.
- Die-Cutting & CNC Forming: Laser or CNC die-cutting ensures precise dimensions & rounded corners; pouch profiles defined at micron level.
- Eight-Side Sealing: State-of-art automatic eight-sided sealing using automated servo-driven machinery. Seal integrity validated by ASTM F88 burst and peel tests.
- Pouch Shaping & Bottom Gusseting: Specialized tooling shapes the unique octagonal “block bottom,” maximizing volume and stability.
- Bag Inspection & Quality Assurance: 100% batch-level leak, tensile, friction, and pinhole tests. Compliance with ISO 9001:2015, ANSI/ASQ Z1.4 and EU REACH standards.
- Final Finished Product & Packing: Custom finishing – zippers, spouts, valves, and PE handles added as required. Securely packed per ISO/ASTM shipping guidelines.
Key Advantages of This Process: Highly automated manufacturing ensures dimensional accuracy (<±0.5mm), consistent sealing, superior shelf appeal, and traceable material sources.
3. Core Material, Technology, and Accrediting Standards
- Main Materials: PET (Polyethylene Terephthalate), NY (Nylon), PE (Polyethylene), AL (Aluminum Foil), BOPP (Biaxially Oriented Polypropylene), and biodegradable films.
- Sealing Technology: The advanced “eight side seal” ensures maximum product protection from spillage, degradation and tampering. Heat-sealing and pressure-formed, validated by ASTM F88-17 Seal Strength Tests.
- Certifications: ISO 9001:2015, FDA 21 CFR 177.1520, EU REACH, SGS, and BRCGS Food Safety. RoHS and BPA-free available upon request.
- Expected Service Life: 2–3 years shelf life (as per ISO/TR 13143-2), with high resistance to puncture, moisture, grease, and light.
- Typical Industries Served: Food & beverage, pet food, nutraceuticals, industrial chemicals, agro products, pharmaceutical intermediates, and premium retail products.
- Technical Advantages: Leak-proof, aroma-retentive, UV/sunlight barrier, anti-static, customizable print and fitments, recyclable/compostable options.
How Octagonal Bag Structure Improves Performance?
- By distributing weight evenly across the eight sealed edges, heavy loads (up to 25kg) can be handled with minimal deformation (<3% bulge rate after 8h, per lab test data).
- Enhanced bottom “block” structure means upright display for gravity-dispensed contents, reducing waste by ~18% and improving production line efficiency (GMA study, 2022).
- Barrier layer permutations (ex: NY/AL/PE) deliver OTR as low as 0.6 while remaining durable in -30°C to +80°C range.
