Introduction to PP Woven Liner Sacks
PP woven liner sacks refer to bags made from a woven polypropylene fabric with an internal polyethylene liner. Key benefits offered:

PP Woven Bags Manufacturing Process
We utilize an advanced manufacturing process to ensure consistent quality of our PP woven bags:
- Raw Material Procurement: We procure polypropylene resin in granule form which is the raw material for weaving PP fabric.
- In-House Weaving: The PP granules are melted and extruded into tapes which are then woven into the fabric using high-speed air-jet looms in our facility. This gives complete control over fabric quality.
- Fabric Processing: The woven fabric is checked and processed by cutting, stitching, and laminating as per product specifications.
- Printing: We use HD digital printing for orders up to 10,000 bags and screen printing for bulk orders above 10,000 bags. This allows us to print small runs cost-effectively.
- Quality Checks: Throughout the production process, quality assurance checks are conducted to ensure consistent quality.
- Packing & Dispatch: The finished bags are packed properly for transportation before being dispatched.
