Custom Woven Bags have emerged as the backbone of modern livestock feed packaging, offering tailored solutions for bulk handling, moisture control, and automated production lines. These bags, also known as Feed-Grade Sacks or Agricultural Woven Pouches, are engineered to withstand 500+ PSI burst forces while adhering to FDA’s stringent safety standards. This report explores their construction intricacies, sealing technologies, and why VidePak’s custom solutions are trusted by feed mills globally.
1.1 Bag Construction: Balancing Durability and Feed Preservation
1.1.1 Fabric Engineering
- Base Material: 90–120 g/m² PP woven tape (400–600 denier) with 450 N/5cm tensile strength (ISO 527-3).
- UV Defense: 2% carbon black additives for 6-month outdoor stability (ASTM G154).
- Moisture Barrier: 15–30 micron BOPP film for 99% humidity resistance (FDA 21 CFR 177.1520).
1.1.2 Seam Technologies
- Stitching:
- Thread: 60–80# polyester with 8–10 stitches/inch (ISO 4916).
- Pattern: Chain stitch for 90% of seams, lock stitch for high-stress zones.
- Heat Sealing:
- Temperature: 180–200°C for 3-second dwell (ISO 11677).
- Width: 8–12mm for 95%+ bond integrity.
- Ultrasonic Welding:
- Frequency: 20–40 kHz for 0.5-second welds.
- Strength: 90% of base fabric tensile strength.
1.1.3 Closure Systems
| Closure Type | Application | Key Features |
|---|---|---|
| Open Mouth | Manual filling | Cost-effective, 50–100 kg capacity |
| Valve | Automated filling (FFS) | 99% dust retention, 25–50 kg fill weights |
| Heat Seal | Hermetic requirements | 0.01 cc/m²/day OTR, 2-year shelf life |
| Stitched | Heavy-duty feed (50–100 kg) | 450 N/5cm seam strength |
1.2 Client ROI: From Waste Reduction to Line Efficiency
1.2.1 Case Study 1: Brazilian Poultry Feed Producer Cuts Losses
Problem: 12% feed degradation due to moisture ingress through stitched seams.
Solution: VidePak’s Heat-Sealed Bags with 15-micron BOPP liners.
Result: 98% feed preservation, $180,000 annual savings in waste.
1.2.2 Case Study 2: European Dairy Co-Op Boosts Throughput
Challenge: Manual stitching limited output to 800 bags/hour.
Solution: VidePak’s Ultrasonic-Welded Bags compatible with 1,200-bag/hour FFS lines.
Result: 50% throughput increase, $360,000 saved in labor costs.
