Paper Valve Woven Bags: Engineering Food Safety Through Custom Innovation

When Food Integrity Meets Packaging Precision

Paper valve woven bags are redefining food packaging—combining 100% recyclable kraft paper with woven PP reinforcement to deliver 30% longer shelf life. At VidePak, we engineer these bags using solar-powered precision and patented valve geometries to meet BRCGS Food Safety standards for Nestlé, Cargill, and 400+ global clients. These aren’t ordinary sacks—they’re hygiene fortresses for flour, sugar, and pet food. Let’s explore how we blend material science with culinary-grade innovation.
