Product Overview

1. Detailed Product Specifications

2. Production Process Flow (Wholesale-Focused)

Step 1: Raw Material Sourcing & Inspection

• Source food-grade PET, PE, and aluminum foil from certified suppliers (with COA—Certificate of Analysis).
• Conduct pre-production tests: Material thickness check (±0.01mm accuracy), tensile strength test (to ensure durability), and food safety screening (no harmful chemicals).

Step 2: Material (Lamination)

• Use solvent-free lamination (eco-friendly, no toxic residues) to bond PET/PE/foil layers.
• Automated lamination machines (capacity: 500m/h) ensure uniform adhesion (no bubbling or peeling).

Step 3: Printing (Brand-Centric)

• For flexo printing: Create custom plates (free for repeat clients) and align colors to brand Pantones.
• For digital printing: Upload client designs (AI/PSD files) and print directly on laminated rolls (fast turnaround for small bulk orders).
• Post-print inspection: Check for color consistency, smudges, and logo clarity (100% visual check for first 100 units; random sampling for bulk).

Step 4: Pouch Cutting & Moulding

• Automated cutting machines (precision: ±0.5mm) cut laminated rolls into pouch blanks (matching client dimensions).
• Heat-seal the bottom gussets (temperature: 180–200°C) to create stand-up stability.

Step 5: Zipper Installation

• Ultrasonic welding technology attaches sliders to pouches (ensures airtight seal; no loose zippers).
• Add tear notches (if requested) via die-cutting (clean, easy-to-tear edges).

Step 6: Quality Control (Wholesale Critical)

• Seal Test: Inflate pouches to 0.3MPa pressure (hold for 30 seconds) to check for leaks (reject rate < 0.1%).
• Bearing Test: Hang 2x the pouch’s rated capacity (e.g., 4kg for 2kg pouches) for 1 hour (no tearing).
• Print Check: Randomly select 5% of bulk orders to verify print alignment and color accuracy.

Step 7: Packaging & Bulk Storage

• Pack pouches in corrugated cartons (500–1,000 units per carton; labeled with batch number, size, and client name).
• Store in climate-controlled warehouses (20–25°C, 50–60% humidity) to prevent material degradation.

3. Quality Assurance & Compliance

• Eco-Friendliness: Recyclable PET/PE materials (optional compostable PE for sustainable brands).
• Lab Testing: Third-party lab reports available (upon request) for heavy metals, migration, and tensile strength.
