SOS Bags: Agricultural Packaging Solutions for Flour and Rice

The Spoilage Crisis: How 22% of Grain Losses Occur Post-Harvest

In an era where 22% of global grain production is lost post-harvest (FAO 2024), Self-Opening-Sack (SOS) bags have emerged as the critical solution for agricultural packaging. At VidePak, we’ve engineered these systems to achieve 99.1% barrier integrity while maintaining 98.8% defect-free production. Our 568-strong team, averaging 18 years of packaging engineering experience, operates at the material science frontier, creating SOS bags that outperform industry benchmarks across 19 critical performance metrics.
