The packaging world has evolved far beyond basic functionality. Today’s buyers demand bags that protect products, turn heads on retail shelves, and align with sustainability goals. Enter woven bags with PE liners—a category where VidePak has redefined excellence through 17 years of relentless innovation. These bags aren’t just containers; they’re custom-engineered solutions that balance aesthetic versatility with industrial-grade performance.
Decoding the Specs: Thickness, Weight, and Size Demystified
Selecting the right woven bag with a PE liner feels like navigating a alphabet soup of specifications. Let’s break down the essentials:
1. PE Liner Thickness: Not All Microns Are Created Equal
- Light-Duty Applications: 80–120 microns for dry goods (e.g., rice, pet food).
- Heavy-Duty Demands: 150–200 microns for chemicals or abrasive materials.
- VidePak’s Edge: Our Starlinger RV 132 HD extruders maintain ±5% thickness consistency—critical for avoiding weak points.
2. Fabric Grammage: The Weight-Performance Balance
- Economy Grade: 60–90 gsm for single-use packaging (e.g., e-commerce mailers).
- Premium Grade: 150–180 gsm for reusable tote bags or branded merchandise.
- VidePak’s Edge: W&H VarioWeb 8000 looms ensure ±3% grammage uniformity, preventing uneven seams.
3. Dimensional Flexibility: Size Matters (But So Does Precision)
- Standard Sizes: 40x60cm to 90x120cm (think fertilizer sacks to retail shopping bags).
- Customization Sweet Spot: VidePak excels at non-standard sizes (e.g., 35x55cm for coffee beans).
- VidePak’s Edge: JUKI DDL-9000B cutters deliver ±1cm accuracy, critical for automated filling lines.
Parameter Selection: A Real-World Playbook
| Application | Thickness (Microns) | Grammage (GSM) | Size (cm) | Why It Works |
|---|---|---|---|---|
| Agricultural Seeds | 80–100 | 60–80 | 50×80 | Thin liners prevent seed oil migration. |
| Chemical Powders | 150–200 | 150–180 | 75×105 | Thick liners resist corrosion and punctures. |
| E-Commerce Apparel | 120–150 | 90–120 | 45×60 | Medium weight balances print quality and cost. |
| Retail Pet Food | 100–120 | 80–100 | 30×45 | Moderate specs meet FDA moisture requirements. |
