In protein powder packaging, flexible formats such as sachets, stick packs, and pillow bags offer the best balance between product protection, sustainability, and operational efficiency. Each serves a distinct role: sachets deliver precise portioning with minimal oxygen exposure, stick packs optimize film usage and high-speed output, and pillow bags provide strength and stability for larger retail or foodservice formats.
To achieve consistent quality, these formats are produced on vertical form fill seal (VFFS) systems specifically engineered for protein powder packaging. Such machines must maintain precise film tension, stable sealing temperatures, and clean filling environments to prevent dust contamination or seal failure. When paired with auger or volumetric fillers, these systems ensure accurate dosing, reliable seals, and a streamlined packaging process designed for long-term performance and sustainability.
