SOS Woven Bags: Engineering Retail Packaging for Efficiency and Safety

The Evolution of Retail Packaging: From Basic Sacks to Smart Solutions

Self-Opening Sacks (SOS) revolutionized retail operations when introduced in 1970s supermarkets. These pre-formed bags with diagonal seams and vent holes transformed filling processes, reducing labor costs by 40% compared to traditional flat bags. Modern SOS woven bags now integrate:

• ErgoHandles™: Patented die-cut handles with ergonomic 35mm width
• MicroVent™ System: 0.5mm laser-drilled holes for controlled respiration
• SlipSafe™ Coating: Silica-based texture reducing pallet movement by 62%

VidePak’s production capabilities include:

• 120+ Starlinger Circular Looms: Weaving 55-180g/m² fabrics with 14×14 to 20×20 mesh
• 8 W&H Flexo Presses: 8-color HD printing at 120m/min with 97% PANTONE® match
• Lamination Lines: Solvent-free adhesive systems meeting EU food contact standards

Certification Highlights:

• ISO 22000:2018: Food safety management certification
• SEDEX SMETA 6.1: Ethical trade audit compliance
• ASTM D6400: Compostable formulations for eco-conscious brands
