Technical Evolution: From Artisanal Beginnings to Industry 4.0

1. Historical Milestones

The valve bag’s journey mirrors industrial progress:

1930s: Hand-sewn jute bags with rudimentary valves emerged in Europe
1960s: PP woven sacks replaced jute, introducing hot-melt glue sealing
1990s: BOPP lamination enabled high-definition graphics for branding

Game-Changing Moments:

2010: VidePak launched China’s first fully automated valve bag line
2018: Starlinger’s viscotec extrusion coating redefined barrier performance
2025: AI-driven quality systems achieve 99.95% defect-free production
