The production of recyclable PP woven bags combines advanced manufacturing technologies, sustainable material choices, and deep market insights to deliver packaging solutions that meet global demands for durability, customization, and environmental responsibility. At VidePak, our 30+ years of industry expertise, state-of-the-art Starlinger machinery, and commitment to ISO-certified processes ensure that our PP woven bags—including BOPP laminated, valve, and kraft paper composite variants—achieve tensile strengths of up to 1,200 N/cm², support 10-color printing precision, and align with diverse regional regulations from the EU’s REACH to North America’s FDA standards.
1. Introduction to Recyclable PP Woven Bags
Polypropylene (PP) woven bags are a cornerstone of modern industrial and consumer packaging, valued for their lightweight yet robust structure, recyclability, and adaptability. These bags are engineered by weaving polypropylene tapes into fabric, followed by lamination or coating to enhance functionality. At VidePak, we produce over 50 million PP woven bags annually, serving industries ranging from agriculture (fertilizers, animal feed) to construction (cement, chemicals) and retail (custom-branded shopping bags).
Our production process integrates 100+ circular looms, 16 extrusion lines, and 30+ lamination machines, enabling us to tailor bags to regional market preferences—such as high-gloss finishes for European retail or heavy-duty UV stabilization for Middle Eastern climates.
2. The Production Process: Precision and Sustainability
2.1 Raw Material Selection
VidePak uses 100% virgin PP granules to ensure consistent quality and compliance with food-grade and chemical-resistant standards. Unlike recycled PP, virgin material offers superior tensile strength (12–14 g/denier) and resistance to moisture, acids, and abrasion.
2.2 Extrusion and Weaving
- Extrusion: PP granules are melted and extruded into flat tapes (width: 2–5 mm; thickness: 0.03–0.05 mm).
- Weaving: Tapes are woven on circular looms into fabric rolls (common densities: 8×8 to 14×14 strands per inch), achieving load capacities of 25–50 kg depending on bag design.
2.3 Lamination and Printing
- BOPP Lamination: A bi-axially oriented polypropylene film is heat-bonded to the woven fabric, enhancing barrier properties against humidity and dust. This process is critical for packaging hygroscopic materials like fertilizers.
- Multi-Color Printing: Our 10-station flexographic printers support Pantone-matched designs, ideal for brands requiring vivid logos or regulatory labeling (e.g., OSHA-compliant hazard symbols).
2.4 Cutting and Sewing
Automated cutting machines ensure dimensional accuracy (±2 mm tolerance), while ultrasonic sealing or lock-stitching provides seam strengths exceeding 300 N.
2.5 Quality Control
Every batch undergoes:
- Tensile strength testing (ASTM D5034).
- UV resistance verification (500+ hours in QUV accelerated weathering chambers).
- Load testing (150% of rated capacity).
3. Market-Specific Adaptations
VidePak’s global reach—spanning 80+ countries—is built on tailoring products to regional demands:

4. Product Range and Certifications
VidePak’s portfolio includes:
- BOPP Laminated Woven Bags: Ideal for retail branding, with moisture barriers (<0.5% water vapor transmission).
- Valve Bags: Precision-filled via automated spouts, reducing spillage by 30% in powdered goods packaging.
- Kraft Paper Composite Bags: Combine PP’s strength with kraft’s biodegradability, meeting EU Directive 94/62/EC.
Certifications: ISO 9001, ISO 14001, BSCI, and Sedex, ensuring ethical production and traceability.
5. FAQs: Addressing Buyer Concerns
Q1: How does VidePak ensure color consistency in custom printing?
A: We use spectrophotometers for real-time color matching and conduct pre-production lab dips to align with Pantone codes.
Q2: What is the lead time for a 20,000-unit order?
A: Standard production takes 18–25 days, including prototyping and quality checks. Urgent orders (8–12 days) are available.
Q3: Are VidePak’s bags suitable for hazardous chemicals?
A: Yes. Our UN-certified FIBC bulk bags withstand corrosive substances, with inner liners made from HDPE or laminated PET.
Q4: How do you support sustainability?
A: We offer recyclable PP blends and closed-loop recycling programs, reducing landfill waste by 40% for partners like Carrefour.
