About this product

Product information from the supplier.

Our BOPP Inner Coated Bags represent the pinnacle of modern industrial packaging, seamlessly integrating the high mechanical strength of PP woven fabric with a sophisticated Biaxially Oriented Polypropylene (BOPP) film and a specialized moisture-proof internal coating. This advanced hybrid construction creates an impermeable barrier that protects your critical products from humidity, oxidation, and external contaminants, making it the definitive choice for chemicals, minerals, and food-grade powders.

Engineered for high-performance industrial applications, these bags feature a premium surface designed for high-resolution photorealistic printing, significantly enhancing brand visibility while maintaining structural integrity during rigorous transport and stacking. By integrating the liner directly into the bag structure, our solution eliminates the need for separate PE liners, streamlining your packaging workflow and drastically reducing material waste.

Frequently Asked Questions

Q: What is the main difference between a standard PP woven bag and a BOPP Inner Coated bag?

Standard PP woven bags are breathable and basic. BOPP Inner Coated bags add a laminated film for superior printing and an internal coating that provides a moisture-proof barrier, eliminating the need for separate plastic liners.

Q: Can these bags be used for food-grade products?

Yes, our BOPP Inner Coated bags can be manufactured using virgin, food-grade materials to ensure safety and compliance with international food packaging standards.

Q: How does the inner coating help in reducing costs?

By integrating the moisture barrier directly into the bag, you remove the labor and material costs associated with inserting a separate PE liner bag into every unit.

Q: What printing options are available for BOPP bags?

We offer high-resolution rotogravure printing, which allows for photographic images, complex gradients, and vibrant colors that do not fade or peel.

Q: Are these bags suitable for automated filling machines?

Absolutely. They are designed to be compatible with most automatic filling and sealing equipment used in the plastics and chemicals industry.

Q: What is the typical lead time for customized BOPP coated bags?

Lead times vary depending on order volume and design complexity, but typically range from 15 to 25 days following artwork approval.
