VidePak’s custom woven bags combine 30+ years of material science innovation with rigorous food safety compliance, reducing product spoilage by 15–40% while enhancing supply chain efficiency for flour, sugar, spices, and food additives. With tensile strengths up to 70 N/cm² (ISO 527-3), FDA-compliant PE laminations, and UV-resistant printing, these bags meet the exacting demands of global food safety standards like EU 1935/2004 and FSSC 22000. Since 2008, VidePak has delivered 600 million+ bags to clients like Cargill and Unilever, leveraging 100+ Starlinger looms and 30 lamination machines to achieve defect rates below 0.03%.
Historical Evolution: From Jute to High-Tech PP
The journey of woven bags began with jute in the 19th century but faced limitations in moisture resistance and durability. Polypropylene (PP) emerged in the 1960s as a game-changer:
- 1960s–1980s: Basic PP bags with 8×8 weave density for grain storage.
- 1990s–2000s: Introduction of BOPP laminations (15–20µ) for moisture barriers.
- 2010s–Present: Smart bags with QR codes, RFID tags, and recycled PP blends.
Case Study: A Mexican flour mill switched from jute to VidePak’s 120 gsm PP bags in 2015, achieving a 22% reduction in insect infestation and 18% longer shelf life.
Food-Specific Packaging Requirements & Solutions
Different food commodities demand tailored engineering approaches:
1. Flour & Grain Powders
- Key Challenges: Moisture absorption (>12% RH causes clumping), pest infiltration (Tribolium spp.).
- VidePak Solutions:
- Material: 100–140 gsm PP with 14×14 weave density (blocks particles >0.5 mm).
- Lamination: 25µ BOPP coating reduces moisture permeability to 1.2 g/m²/24h (ASTM E96).
- Certifications: FDA 21 CFR 177.1520, ISO 22000.
2. Sugar & Sweeteners
- Key Challenges: Crystallization under humidity, UV-induced discoloration.
- VidePak Solutions:
- UV Stabilization: TiO2 additives in PP resin block 99% UV-A/B (ISO 4892-2).
- Anti-Static Liners: Carbon-black PE layers (10⁶–10⁸ Ω/sq) prevent dust adhesion.
3. Spices & Food Additives
- Key Challenges: Volatile compound loss, light-induced oxidation.
- VidePak Solutions:
- Aluminum Foil Liners: 40µ foil laminates (ASTM F392) with O₂TR <0.1 cc/m²/day.
- Aroma-Blocking: Multi-layer PE/PP structures retain 98% essential oils (GC-MS tested).
Technical Specifications by Application
| Product | Fabric Weight | Lamination | Inner Liner | Key Certifications |
|---|---|---|---|---|
| Wheat Flour | 120–140 gsm | 25µ BOPP | None | FDA, FSSC 22000 |
| Crystalline Sugar | 100–120 gsm | 30µ PE | Anti-static PE | EU 1935/2004 |
| Paprika Powder | 90–110 gsm | 40µ Aluminum foil | Kraft paper | ISO 22000, Halal |
| Citric Acid | 130–150 gsm | 50µ PE-coated kraft | PE liner | HACCP, Kosher |
FAQs: Optimizing Food Packaging Decisions
- How thick should PP bags be for 25kg flour?
Use 120–140 gsm PP with 14×14 weave (burst strength ≥350 kPa, ASTM D3786). - Can printed inks contaminate food?
Our soy-based inks comply with FDA 21 CFR 175.300 for indirect contact. - What liner prevents spice oxidation?
Aluminum foil (40µ) + PE coating reduces O₂ permeability to 0.05 cc/m²/day. - Are bags recyclable?
Yes. 100% PP construction meets ISO 15270 standards; 30% recycled options available. - How to prevent sugar caking in humid climates?
Pair 30µ PE lamination (MVTR 0.8 g/m²/24h) with silica gel desiccant sachets.

Case Study: Enhancing Shelf Life for Indonesian Spice Exporter
A turmeric powder supplier adopted VidePak’s triple-layer bags (90 gsm PP + 40µ foil + 50µ PE):
- Challenge: 35% aroma loss during 6-month sea transit.
- Solution: Oxygen barrier liners + UV-resistant outer print.
- Results:
- Quality Retention: 98% curcumin content (HPLC tested).
- Market Value: 20% price premium due to premium packaging.
Sustainability & Regulatory Compliance
- Circular Economy: Post-consumer PP recycled into non-food grade bags (30% blend).
- EPR Alignment: Compliant with EU Packaging Directive 94/62/EC (heavy metals <100 ppm).
- Carbon Metrics: Solar-powered plants reduce CO2 by 150 tons/month vs. 2019 baseline.
