From Polymer to Packaging: How Tan Hung JSC Manufactures High-Quality PP Woven Bags

In today’s global supply chain, durable, cost-effective, and sustainable packaging is essential. Businesses transporting agricultural products, fertilizers, chemicals, rice, sugar, and construction materials require packaging that protects goods, withstands long-distance shipping, and maintains consistent quality.

At Tan Hung JSC, a leading Vietnamese PP woven bag manufacturer, we have perfected the full production journey — from raw polymer to finished bag. Our vertically integrated process ensures every bag meets international standards, delivering strength, durability, and reliability for clients worldwide.

The Manufacturing Process: From Polymer to Finished Bag

Producing a high-quality PP woven bag involves multiple steps, each crucial for strength, durability, and performance.

1. Raw Material Selection

The foundation of every strong PP woven bag starts with high-grade virgin polypropylene granules. Sourced from reputable suppliers, virgin PP ensures:

  • High tensile strength for heavy loads

  • Consistent color and appearance

  • Longer lifespan and improved recyclability

Using recycled or substandard material can compromise bag performance during transport, which we strictly avoid.

2. Extrusion & Taping

Polypropylene granules are melted in an extruder to form thin films. These films are cut into narrow tapes and stretched to align polymer chains, increasing tensile strength and flexibility.

We carefully monitor:

  • Tape width and thickness

  • Tensile strength and elongation

  • Shrinkage rate

Our continuous tape lines produce thousands of kilometers of PP tape daily, ensuring uniformity and quality.

3. Weaving the Fabric

Tapes are woven on high-speed looms into the signature PP woven fabric. This mesh-like structure gives bags strength, flexibility, and load-bearing capacity.

We offer:

  • Various mesh densities (10×10, 12×12, 14×14, etc.)

  • Standard and custom widths (40cm to 90cm+)

  • Tubular and flat fabric options

  • White, transparent, or colored fabrics

This flexibility allows clients to select fabric type and size based on their product requirements.

4. Lamination & Printing (Optional)

Lamination adds a protective barrier against moisture, pests, and contamination. Tan Hung JSC uses BOPP or PE lamination depending on the application.

Benefits of lamination:

  • Water-resistant packaging

  • Glossy or matte finish

  • Photo-quality multicolor printing

We also offer:

  • Flexographic printing for simple logos or text

  • Rotogravure printing for premium retail packaging

Lamination and printing are critical for product branding and protection, especially for food, chemicals, and retail products.

5. Cutting, Stitching & Finishing

Once woven and laminated, fabric is cut and stitched according to customer specifications. Options include:

  • Bag dimensions: 50×75 cm, 60×100 cm, 70×110 cm, or custom sizes

  • Top finish: Hemmed, heat cut, or zigzag

  • Bottom stitch: Single/double fold, single/double stitch

  • Special features: Gusseted sides, block bottom for shape retention, HDPE/LDPE liners, handle cut-outs, anti-slip coatings

Our automated stitching lines and skilled operators ensure uniformity, fast production, and consistent quality.

6. Inspection & Quality Control

At Tan Hung JSC, quality is non-negotiable. Our ISO 9001-compliant QA team inspects:

  • Bag weight (grams per piece)

  • Tensile strength and load-bearing capacity

  • Dimensional accuracy

  • Printing alignment and lamination quality

Only bags passing strict quality standards are packed for shipment.

7. Packing, Logistics & Export

Finished bags are baled and palletized for container loading. Our logistics team ensures smooth export to any port worldwide, handling documentation including:

  • Certificate of Origin (CO)

  • Phytosanitary Certificates

  • Form E for preferential trade

We offer:

  • Flexible minimum order quantities

  • Full container load (FCL) and less than container load (LCL) options

  • Sample dispatch via FedEx, DHL, or TNT
