VidePak’s kraft paper woven bags combine exceptional durability, eco-friendliness, and unparalleled customization to meet global industrial packaging demands. With a tensile strength of 30–50 N/5cm, moisture resistance up to 90% RH, and load capacities exceeding 50 kg, these bags are engineered for heavy-duty applications such as cement, animal feed, and chemical storage. Supported by 100+ circular looms and 30+ lamination machines, VidePak delivers tailored solutions—from valve designs to multi-layer prints—ensuring compliance with regional standards and sustainability goals.
1. Core Characteristics of Kraft Paper Woven Bags
Kraft paper woven bags integrate kraft paper’s natural rigidity with polypropylene (PP) woven fabric’s flexibility, creating a hybrid material ideal for demanding logistics environments.
1.1 Structural Integrity and Durability
The laminated structure typically includes:
- Outer Layer: 80–120 GSM kraft paper, providing tear resistance and printability.
- Middle Layer: PP woven fabric (70–100 GSM), enhancing tensile strength and puncture resistance.
- Inner Layer (Optional): PE coating or aluminum foil for moisture or UV protection.
For example, VidePak’s 20 kg cement packing bags utilize 100 GSM kraft paper laminated with 90 GSM PP fabric, achieving a burst strength of 250 kPa—surpassing ISO 2226:2002 standards.
1.2 Environmental and Functional Advantages
- Biodegradability: Kraft paper decomposes within 2–5 months, reducing landfill impact compared to pure plastics.
- Breathability: Ideal for agricultural products like rice or seeds, preventing condensation and spoilage.
- Reusability: PP woven fabric enables 3–5 reuse cycles, lowering long-term costs.
2. Customization Capabilities for Diverse Market Needs
VidePak’s R&D team tailors every aspect of kraft paper woven bags to align with client specifications and industry regulations.
2.1 Design Customization
| Feature | Options | Applications |
|---|---|---|
| Valve Types | Pasted valve, block-bottom valve, spout | Cement, flour, powdered chemicals |
| Handles | Loop handles, die-cut grips | Retail shopping bags, pet food packaging |
| Thickness | 0.15–0.3 mm (adjustable layers) | Heavy-duty mining, lightweight agriculture |
| Printing | Up to 8-color flexography, CMYK offset | Branded retail bags, hazard warnings |
For instance, a European client requested 50,000 laminated bags with QR-code-readable safety instructions for fertilizer storage, achieved through high-definition offset printing.
2.2 Material Innovations
- Anti-static Liners: Critical for packaging explosive powders in the chemical industry.
- Food-Grade PE Coating: Meets FDA standards for direct contact with edible products.
3. Storage Solutions to Prolong Shelf Life
Improper storage compromises bag integrity. VidePak recommends:
3.1 Environmental Controls
- Temperature: Store below 40°C to prevent PP fabric degradation.
- Humidity: Maintain <60% RH; silica gel packets can mitigate moisture absorption.
3.2 Stacking and Handling
- Palletization: Stack vertically, limiting height to 8 layers (20 kg/bag) to avoid compression damage.
- UV Protection: Use shaded warehouses; laminated UV-resistant layers extend outdoor usability by 12 months.
4. VidePak’s Manufacturing Excellence
Founded in 2008, VidePak operates 16 extrusion lines and 30 lamination machines, producing 10 million bags monthly. Key strengths include:
- Austrian Starlinger Machinery: Ensures seam strength consistency (±5% tolerance).
- Global Compliance: Certifications include ISO 9001, REACH, and USDA BioPreferred.
5. Frequently Asked Questions (FAQs)
