“Our customers often ask: How can we balance sustainability with functionality in bulk packaging?”
“The answer is clear,” says Ray Chiang, CEO of VidePak. Fabric polypropylene (PP) woven bags offer unparalleled durability, cost-efficiency, and eco-friendly advantages, making them the cornerstone of modern industrial and agricultural packaging.
For over 17 years, VidePak has leveraged its 30+ years of industry expertise and cutting-edge manufacturing capabilities to deliver tailored PP woven bag solutions. With a workforce of 526 professionals and a global footprint generating $80 million in annual sales, we combine innovation with sustainability to meet the evolving demands of industries ranging from agriculture to construction.
The Science of Customization: Addressing Diverse Product Needs
PP woven bags are not a one-size-fits-all solution. Different products—such as seeds, grains, coffee beans, or starch—require specific design considerations to ensure optimal protection, shelf life, and transport efficiency. Below, we analyze key requirements across applications:
1. Seed Packaging: Balancing Breathability and Moisture Control
Seeds demand precise moisture and oxygen exchange to maintain germination rates. PP bags with controlled permeability (measured in g/m²/24h) prevent mold while allowing minimal airflow. For example, maize seeds stored in bags with a 90-100 g/m²/24h moisture vapor transmission rate (MVTR) show a 95% germination rate after 12 months, compared to 70% in non-breathable alternatives. VidePak’s BOPP laminated woven bags integrate micro-perforations to achieve this balance, ensuring seed viability even in humid climates.
Critical Parameters:
- Fabric Weight: 80–100 g/m² for structural integrity.
- Lamination: Optional BOPP coating for UV resistance.
- Inner Liners: Biodegradable PE liners for added moisture control.
2. Nut and Coffee Bean Packaging: Preventing Oxidation and Pest Infestation
Nuts and coffee beans are prone to rancidity and insect damage. Anti-static PP woven bags with aluminum foil layers block oxygen ingress (reducing oxidation by 40%) and deter pests. For example, VidePak’s kraft paper laminated bags use a 12µ aluminum foil layer to extend coffee bean freshness by 6–8 months.
Critical Parameters:
- Thickness: 0.18–0.25 mm for puncture resistance.
- Closure Systems: Heat-sealed valves to prevent tampering.
3. Grain and Starch Packaging: Stackability and Moisture Resistance
Wheat, rice, and starch require bags that withstand stacking pressures of up to 8 tons per pallet while resisting humidity. VidePak’s FIBC bulk bags with woven PP + PE liners achieve a moisture barrier efficiency of 99.5%, critical for tropical markets.
Critical Parameters:
- GSM (Grams per Square Meter): 120–150 GSM for heavy-duty use.
- UV Stabilizers: Added to outer layers for outdoor storage.
Optimizing Product Parameters: A Data-Driven Approach
Selecting the right PP woven bag involves evaluating four key factors:
| Parameter | Seed Bags | Nut/Coffee Bags | Grain Bags |
|---|---|---|---|
| Fabric Weight | 80–100 GSM | 100–120 GSM | 120–150 GSM |
| Lamination | BOPP (optional) | Aluminum foil | PE coating |
| Breathability | High MVTR | Low MVTR | Moderate MVTR |
| Closure Type | Sewn mouth | Heat-sealed valve | Pasted valve |
Case Study: A soybean exporter in Brazil reduced post-harvest losses by 22% after switching to VidePak’s 120 GSM BOPP laminated bags with integrated insect-repellent additives.

- Smart Printing: 10-color rotary printers enable high-definition branding while reducing ink waste by 30%.
FAQs: Addressing Client Concerns
Q: How do I choose between laminated and non-laminated bags?
A: Lamination (e.g., BOPP) enhances moisture and UV resistance but reduces breathability. For seeds, use partial lamination; for grains, full lamination is ideal.
Q: What GSM is suitable for 50 kg rice packaging?
A: 90–110 GSM provides optimal strength-to-weight ratios. VidePak’s FIBC bags with 150 GSM handle up to 2,000 kg safely.
Q: Can PP bags be recycled?
A: Yes. VidePak’s reLÜ™ series uses 30% post-consumer recycled PP, reducing carbon footprint by 40%.
