VidePak stands at the forefront with its premium Kraft Paper Sacks. Combining decades of expertise in woven packaging solutions with cutting-edge manufacturing technologies, our kraft paper sacks redefine reliability across industries.
Product Specifications: Precision Meets Performance
VidePak’s kraft paper sacks are engineered to withstand rigorous handling while adhering to international quality benchmarks. Key specifications include:
- Material Composition: 100% virgin or recycled kraft paper (70–150 g/m² basis weight), laminated with food-grade polypropylene (PP) or polyethylene (PE) coatings for moisture resistance.
- Thickness: 0.15–0.30 mm, customizable based on load requirements.
- Load Capacity: 5–50 kg, validated through ISO 2226:2018 compression testing.
- Printing: Up to 8-color flexographic printing with resolution ≤0.1 mm deviation, certified by Pantone Matching System (PMS) standards.
A recent third-party evaluation by Smithers Pira highlighted that VidePak’s 120 g/m² kraft paper sacks achieved a tensile strength of 12 kN/m, exceeding industry averages by 18%.
Production Process: Quality Embedded at Every Stage
VidePak’s manufacturing workflow integrates Austrian Starlinger and German W&H machinery, ensuring precision across six critical phases:
- Raw Material Preparation
- Kraft Pulp Refining: Pulp is treated with sodium hydroxide and sodium sulfide (Kraft process) to enhance fiber strength.
- Quality Control: Incoming pulp batches undergo ISO 5351:2010 viscosity testing to verify cellulose integrity.
- Sheet Formation (Fourdrinier Machine)
- The pulp slurry is spread onto a moving mesh, dehydrated, and pressed into continuous sheets.
- VidePak’s real-time moisture sensors (accuracy ±0.5%) ensure uniform grammage (70–150 g/m²).
- Lamination and Coating
- Extrusion lamination (160–200°C) bonds PP/PE films to kraft sheets for waterproofing.
- Defect Detection: Laser scanners identify pinholes or air bubbles, rejecting substandard rolls automatically.
- Sack Construction
- High-speed circular looms weave laminated sheets into tubular sacks. Seam strength is validated via ASTM D5265 peel tests (≥4 N/mm).
- Printing and Customization
- Advanced CI flexo printers apply logos or safety labels using REACH-compliant inks.
- Final Inspection
- A 3-stage QA process includes:
- Load Testing: Simulated drops from 1.2 m (ISTA 3A standard).
- Print Accuracy: Spectrophotometer analysis (ΔE ≤2.0).
- Certification: Compliance with FDA 21 CFR §176.170 (food contact) and EU 10/2011.
Future Trends: Aligning with Global Sustainability Goals
The packaging industry’s shift toward circular economies drives VidePak’s R&D focus:
- Enhanced Recyclability
- Our kraft paper sacks are certified FSC Mix Credit (license code FSC-C154786) and comply with EN 13432 compostability standards.
- A 2025 study by Maastricht University warned of heavy metal leaching in recycled paper packaging. VidePak addresses this by using non-toxic, soy-based adhesives and water-based coatings.
- Industry-Specific Customization
- Agriculture: Anti-static sacks for fertilizer storage (surface resistivity ≤10^9 Ω/sq, per IEC 61340-5-1).
- Food & Beverage: Oxygen barrier layers (OTR ≤5 cc/m²/day) extend shelf life for coffee beans.
- Construction: 3-ply reinforced sacks with puncture-resistant liners for cement transport.
A case study with a European pet food manufacturer demonstrated a 30% reduction in transport damage after switching to VidePak’s custom-designed sacks, yielding an ROI of 14 months.
