FFS Woven Bags: The Engineering Behind Precision Form-Fill-Seal Packaging

When Speed Meets Strength: The FFS Packaging Revolution

FFS woven bags aren’t just containers—they’re precision-engineered systems that marry form-fill-seal automation with woven polypropylene’s durability. At VidePak, we’ve spent 17 years perfecting a 17-step production process that transforms raw polymer into bags capable of withstanding 50–100 kg loads while supporting 8-color branding. Our edge? $60 million in precision machinery from Starlinger and W&H, paired with a quality control system that rejects 0.3% of production—10x stricter than industry averages.
