Production Process of PP Self-Sealing Bags at Sao Do Viet Nam

Step 1: Raw Material Preparation
Virgin PP resin meeting quality standards is used, ensuring transparency, flexibility, and safety when in contact with products.
Step 2: PP Film Blowing
The resin is melted and blown into thin film according to the required thickness. The film is inspected for tensile strength, transparency, and flexibility before moving to the next stage.
Step 3: Cutting and Bag Sealing
After film blowing, the PP film is cut to the required dimensions and then heat-sealed using specialized sealing machines to ensure strong, non-peeling edges.
Step 4: Quality Inspection
Finished bags are checked for size accuracy, thickness, sealing tightness, and overall appearance before packaging.
Step 5: Packaging and Delivery
Products are neatly packed to prevent dust and moisture, then delivered to customers on schedule.
