Product Q&A

Q:What is the difference between an inner bag and a laminated bag?

An inner bag is a separate PE liner inserted inside the woven sack, offering superior moisture protection and preventing fine powder leakage. A laminated bag has a film bonded to the outer surface, which is better for high-quality printing.

Q:Can the inner liner be customized for food-grade materials?

Yes. We offer 100% virgin PE inner liners that are odorless and meet international food safety standards, making them safe for packaging grains, flour, and sugar.

Q:What is the minimum order quantity (MOQ) for custom woven bags?

To support our clients, we offer flexible MOQs. Small trial orders are welcome for testing the market, and we also provide free samples for quality check before bulk production.

Q:How do you ensure the bags won't break during heavy transport?

We use high-density weaving technology and reinforced stitching at the bottom. Our heavy-duty bags can safely hold 50kg+ and are tested for strong tensile strength and drop resistance.
