Product Q&A
Q:What is the MOQ for custom printed valve bags?
A:
For custom printed designs, our MOQ is typically 20,000 pieces. However, for first-time cooperation, we can discuss a smaller trial order quantity. Please contact us with your details.
Q:What materials are your paper valve bags made of?
A:
Our paper valve bags are mainly made from high-quality Virgin Kraft Paper. We can also add an inner PE liner or lamination for moisture resistance, depending on your product requirements.
Q:Can I get different ply (layer) options?
A:
Yes, we offer various ply options ranging from 2-ply to 6-ply. The most common for cement and chemical powders are 3-ply and 4-ply bags. You can choose based on the weight and abrasiveness of your products.
Q:What is the difference between a pasted valve and a sewn valve?
A:
A pasted valve uses adhesive to seal the valve, providing better sift-proof properties for fine powders. A sewn valve is stitched closed, which is generally stronger for heavier materials but may have tiny needle holes. We can provide both based on your needs.
Q:Can you print my logo on the bags? What printing methods do you use?
A:
Yes, we offer custom printing services. We typically use Flexo Printing (for cost-effective, large-area color) and Offset Printing (for high-definition, detailed designs). We can print up to 4-6 colors depending on the design.
