About this product

Product information from the supplier.

Our PP Woven Bag with Inner Coated is a high-performance packaging solution engineered for industries requiring maximum product protection. By integrating a durable polypropylene woven exterior with a specialized inner coating, these bags provide a formidable barrier against moisture, leakages, and external contaminants, ensuring your materials remain pristine during transit and storage.

Specifically designed for the rigorous demands of the plastics and chemical industries, these coated woven bags combine the structural integrity of PP fabric with the sealing capabilities of a polymer liner. Whether you are transporting powders, granules, or fine chemicals, this hybrid design eliminates the need for separate plastic liners, optimizing your packing process and reducing overall waste.

Frequently Asked Questions

Q: What is the primary difference between a standard PP woven bag and an inner coated one?

Standard bags are breathable and can leak fine powders. Inner coated bags feature a laminated film layer inside that provides a waterproof barrier and prevents fine particles from escaping.

Q: Are these coated bags suitable for food-grade packaging?

Yes, depending on the resin used for the coating. We provide food-grade PP and PE materials that comply with safety standards for agricultural and food products.

Q: Can I customize the printing on the exterior of the coated bag?

Absolutely. We offer high-quality BOPP lamination and flexographic printing to ensure your brand colors and logos are vibrant and durable.

Q: How does the inner coating affect the recyclability of the bag?

Since both the woven fabric and the coating are typically made from Polypropylene (PP) or Polyethylene (PE), the bags remain fully recyclable within the plastic waste stream.

Q: What weight capacities can these bags support?

Our bags are customizable to support various weights, typically ranging from 5kg to 50kg, depending on the fabric density and weave specifications.

Q: Does the coating protect against chemicals?

Yes, the inner coating provides a significant barrier against many chemical agents, making them ideal for fertilizers, resins, and various industrial chemical powders.
