FFS (Form-Fill-Seal) roll woven bags reduce feed packaging costs by 25–40% compared to pre-made bags, while their breathable PP structure maintains <0.5% moisture content to prevent mold growth—critical for preserving nutritional value in animal feeds. At VidePak, our Austrian Starlinger extrusion lines produce 1.5–2.5 mm PP tapes with ±0.03 mm thickness precision, enabling woven fabrics that achieve 35–50 N/cm² tensile strength and controlled 5–10 μm microporosity. For instance, our BOPP-laminated FFS rolls extended poultry feed shelf life by 6 months in Vietnamese monsoons, while vented cattle feed bags reduced dehydration losses by 18% for a Brazilian ranch.

Comparative Table: Feed-Specific Configurations
| Parameter | Pet Food Bags | Poultry Feed Bags | Livestock FIBC Bags |
|---|---|---|---|
| Thickness | 100–120 g/m² | 140–160 g/m² | 200–250 g/m² |
| Lamination | 20 μm BOPP | 50 μm PE | Non-laminated |
| Microporosity | 5 μm | 8 μm | 10 μm |
| Load Capacity | 25 kg | 40 kg | 1,000 kg |
| Cost per 1,000 Bags | $220–$280 | $180–$240 | $450–$600 |
2. Material Science: Extrusion, Stretching, Weaving
Extrusion: Precision in Polymer Alignment
Starlinger extruders process virgin PP at 230±5°C, optimizing Melt Flow Index (MFI 8–10 g/10min) for:
- Tape Consistency: ±0.02 mm thickness variance prevents weak seams.
- Surface Smoothness: Ra 0.8–1.2 μm enables high-resolution flexo printing.
Tape Stretching: Strength-Flexibility Balance
Monoaxial stretching (5:1 ratio) enhances:
- Tensile Strength: 45 N/cm² vs. 30 N/cm² in non-stretched tapes.
- Elongation Control: Limits bag deformation to <2% under 40 kg loads.
Weaving: Structural Engineering
High-density circular looms (12 tapes/inch) create:
- Abrasion Resistance: 4,000+ Rub cycles for rough-handled cattle feed.
- Controlled Porosity: 8 μm gaps enable 0.5 m³/m²/hour airflow to prevent anaerobic spoilage.
Case Study: A Thai shrimp feed producer reduced waste by 22% using our 12-tape/inch vented bags with 0.03 mm anti-fungal PE coating.
3. Parameter Selection Guide
Thickness & Weight
- 25–40 kg Feeds: 120–150 g/m² woven PP + 30 μm BOPP.
- FIBC Bulk: 200 g/m² + 1.5 mm corner reinforcements.
Lamination & Liners
| Coating Type | Thickness | Moisture Barrier | Best For |
|---|---|---|---|
| BOPP | 20–30 μm | 0.5 g/m²/day | Humid climates |
| PE | 40–60 μm | 0.1 g/m²/day | High-fat feeds |
| Anti-Microbial | 15 μm | N/A | Organic formulations |
Valve & Venting
- Spout Valves: For automated filling lines (600–800 bags/hour).
- Laser Perforations: 0.5–2.0 mm vents for moisture-sensitive grains.
4. FAQs: Technical and Procurement Insights
Q1: How does tape width affect mold resistance?
- A: 2.0 mm tapes reduce inter-filament gaps by 30%, limiting spore infiltration.
