VidePak’s custom-printed sewn open mouth (SOM) PP bags deliver unmatched protection for seeds, grains, and dry foods, reducing spoilage rates by 15–40% through scientifically optimized moisture barriers, UV resistance, and pest deterrence. With tensile strengths of 50–65 N/cm² (ISO 527-3), 8-color HD printing for regulatory compliance, and customizable liners like black PE inner bags, these bags preserve product viability across 12+ months of storage and transit. Since 2008, VidePak has supplied 300 million+ SOM bags globally, leveraging 100+ Starlinger circular looms and 30 lamination machines to meet the exacting demands of agribusiness giants like Bayer and Olam.
Application-Specific Design: Tailoring Bags to Commodity Needs
The unique requirements of agricultural products demand precision engineering. Below we analyze key sectors:
1. Seeds & Legumes: Balancing Aeration and Moisture Control
- Challenge: Seed respiration requires 5–10 g/m²/24h oxygen permeability (ASTM D3985) to maintain germination rates >85%, while preventing humidity ingress (>70% RH risks fungal growth).
- Solution:
- Mesh Design: 8×8 threads/cm² weave with 0.5–1.0 mm gaps for airflow.
- Lamination: 25µ BOPP coating reduces moisture permeability to 2.5 g/m²/24h (vs. 15 g for uncoated).
- Case Study: A Brazilian soybean supplier achieved 92% germination post-6-month storage using VidePak’s SOM bags with 40 gsm PP + 30µ BOPP + black PE liner.
2. Cereals (Rice, Wheat, Corn): Anti-Pest & Stackability
- Challenge: Rice weevils (Sitophilus oryzae) penetrate >1.5 mm gaps; 25 kg bags must withstand 8-layer palletization (1,000 kg/m²).
- Solution:
- Fabric Density: 120–150 gsm PP with 14×14 threads/cm² blocks insect entry.
- Reinforced Seams: Double-stitched seams using UV-resistant polyester thread (ASTM D6193) withstand 600 N pull force.
- Pallet Optimization: Standard 90×50 cm dimensions align with EUR-pallet footprints, enabling 104 bags/pallet.
3. Coffee Beans & Nuts: Light & Odor Protection
- Challenge: UV exposure causes lipid oxidation (rancidity); 500 lux light reduces coffee quality by 30% in 60 days.
- Solution:
- Black PE Liners: 0% light transmission (ASTM D1746), with 0.5% moisture vapor transmission rate (MVTR).
- Carbon-Loaded PP: 2% activated carbon additive absorbs ethylene and volatile odors.
Technical Specifications by Application
| Commodity | PP Weight | Lamination | Inner Liner | Key Certification |
|---|---|---|---|---|
| Seeds | 80–100 gsm | 25µ BOPP | Black PE (50µ) | ISTA 3B |
| Rice/Wheat | 120–150 gsm | None | None | FDA 21 CFR 177.1520 |
| Coffee Beans | 100–120 gsm | 30µ Metallized PET | Aluminum Foil (40µ) | SCA Green Coffee |
| Nuts | 90–110 gsm | 20µ PE | Kraft Paper (80 gsm) | EU Regulation 1935/2004 |
FAQs: Addressing Procurement Complexities
- How do black PE liners improve seed viability?
They block 100% UV light (300–700 nm spectrum), reducing metabolic activity by 60% and extending dormancy. - What bag specs prevent insect infiltration?
Thread density ≥12×12/cm² with gaps <1 mm, verified via ASTM F2132-01 sieve testing. - Can bags withstand maritime humidity?
Yes. 40µ PE lamination achieves MVTR <1 g/m²/24h, complying with ISO 2230 for 95% RH environments. - Are printed inks food-safe?
Our soy-based inks meet FDA 21 CFR 175.300 for indirect food contact. - How to optimize for automated filling?
Specify anti-static coatings (10⁶–10⁸ Ω/sq surface resistivity) and reinforced spouts.

Case Study: Protecting Hybrid Maize Seeds in Kenya
A Nairobi-based agri-cooperative adopted VidePak’s triple-layer SOM bags (90 gsm PP + 30µ BOPP + 50µ black PE):
- Results:
- Germination Rate: 89% after 9 months (vs. 62% in standard bags).
- Pest Damage: 0% infestation vs. 18% industry average.
- ROI: $3.50/bag cost yielded $12.70/bag value retention.
Regulatory Compliance & Sustainability
- Global Certifications: ISO 22000 (food safety), USDA BioPreferred (20% recycled content option).
- Circular Economy: Bags are 100% recyclable (ISO 15270), with post-use PP reprocessed into irrigation pipes.
- Carbon Neutrality: Solar-powered plants reduce Scope 2 emissions by 35% vs. 2020 baseline.
