SOS PP Fabric Bags: Advanced Solutions for Chemical Fertilizer Packaging and Protection


In the global fertilizer industry, 25–30% of product losses occur due to inadequate packaging, costing manufacturers over $2.5 billion annually. At VidePak, we address this challenge head-on with SOS PP fabric bags, engineered to deliver unmatched moisture resistance, corrosion protection, and load-bearing capacity for fertilizers and compound fertilizers. Our ISO 9001-certified bags reduce spoilage rates by 35%, withstand corrosive agents like ammonium nitrate, and comply with EU, US, and Asian safety standards – all while cutting logistics costs by 20% through optimized weight-to-strength ratios. With 30+ years of expertise and 100+ Starlinger circular looms, we serve 45+ countries, producing 80 million bags yearly for clients like Yara International and Nutrien.


1. Critical Challenges in Fertilizer Packaging – How SOS PP Bags Deliver

Moisture Control in Humid Climates

Fertilizers like urea absorb moisture at relative humidity (RH) levels above 60%, causing caking and nutrient degradation. VidePak’s SOS PP bags integrate:

  • BOPP Lamination: Blocks 99% water vapor (0.8 g/m²/24h permeability @38°C, 90% RH – ASTM E96).
  • PE Inner Liners: 80–120 micron thickness for tropical climates (e.g., Southeast Asia).
  • Desiccant Pouches: Optional silica gel inserts for extended storage.

Case Study: A Brazilian NPK producer reduced moisture-related rejects from 8% to 1.2% using our 3-layer laminated SOS PP bags with heat-sealed PE liners.

NPK Compounds150 g/m² laminated PP + anti-static layer

3. Solving Corrosion and Heat Buildup

Chemical Resistance

VidePak’s SOS PP bags utilize:

  • Virgin PP Resin: pH resistance range 2–12 (ISO 175).
  • Acid-Barrier Coatings: Protect against sulfuric acid traces in superphosphate fertilizers.

Thermal Management

  • Ventilated Designs: Micro-perforations (2–5 mm² vents per bag) reduce internal temperatures by 8–10°C during maritime transport.
  • White UV-Reflective Prints: Lower surface temps by 15°C vs. black bags (per 2024 UAE field tests).

4. Regional Compliance: Choosing the Right Parameters

European Markets (EN Standards)

  • Mandatory: ≤0.5% open area for dust retention (EN 14362).
  • Solution: Ultrasonic seam sealing + 150 g/m² fabric.

North America (ASTM/PPAI)

  • Required: 6:1 safety factor for FIBC bags (ASTM D7388).
  • Implementation: 8×8 weave pattern with 14 N/mm² tensile strength.

Asia-Pacific (JIS/GB)

  • GB/T 8947: Requires ≥50 cycles of flex resistance.
  • VidePak Edge: 4-layer laminated corners withstand 200+ flex cycles.

5. FAQs: Expert Answers for Procurement Teams

Q1: How to select inner liner thickness for high-humidity regions?
A: Use 120μ PE liners for RH >70% (e.g., Indonesia), 80μ for RH 50–70% (e.g., Mediterranean).

Q2: Do laminated bags affect recycling compliance?
A: Our BOPP/PE layers separate cleanly during recycling, meeting EU Circular Economy Package 2030 targets.

Q3: What’s the optimal bag weight for 50kg fertilizer portions?
A: 100 g/m² unlaminated (arid climates) vs. 130 g/m² laminated (coastal areas), with ±0.2kg tolerance.
