About this product

Product information from the supplier.

Our premium Industrial PP Woven Bags with Inner Liner are precision-engineered for high-performance packaging requirements. By merging the exceptional tensile strength of heavy-duty polypropylene woven fabric with a specialized internal moisture barrier, these bags provide an uncompromising shield for your industrial goods. This dual-layer architecture is specifically designed to eliminate risks associated with humidity, leakage, and external contaminants during long-distance global transit and rigorous storage conditions.

Tailored for the demanding needs of the chemical and manufacturing sectors, these bags are the ideal solution for transporting fine powders, granules, and specialized chemicals. By integrating high-density polyethylene (HDPE) or low-density polyethylene (LDPE) liners, we deliver a hermetic, leak-proof packaging system that preserves product purity and prevents sifting, ensuring your supply chain logistics remain efficient and waste-free.

Frequently Asked Questions

Q: What is the primary benefit of adding an inner liner to a PP woven bag?

The inner liner provides a critical moisture barrier and prevents fine powders from leaking through the weave of the PP fabric, ensuring product integrity and purity.

Q: Can these bags be customized for specific chemical products?

Yes, we can customize the liner material (LDPE, HDPE, etc.) and fabric density to match the chemical properties and weight requirements of your specific product.

Q: Are the bags UV stabilized for outdoor storage?

We offer UV stabilization additives during the extrusion process, which prevents the PP material from degrading under direct sunlight, extending the bag's lifespan.

Q: What printing options are available for branding?

We provide standard flexographic printing as well as premium BOPP lamination, which allows for photorealistic images and high-gloss finishes for maximum brand impact.

Q: How do you ensure the liner does not detach from the bag?

Depending on your needs, the liner can be loosely inserted or heat-sealed/sewn to the top of the PP bag to ensure it stays securely in place during filling.

Q: What is the typical lead time for bulk orders?

Lead times vary based on customization and order volume, but typically range from 15 to 30 days. Please contact our sales team for a precise timeline.
