Product Q&A

Q:What is the weight capacity of your PP valve bags?

Our PP valve bags can typically hold between 5kg to 50kg, depending on the fabric weight and specifications. Heavy-duty options are available for demanding applications.

Q:Are these bags suitable for automatic filling machines?

Yes, absolutely. The precise square bottom and valve design ensure smooth filling and neat stacking, making them highly compatible with high-speed automatic packaging lines.

Q:Can you print our logo and custom design on the bags?

Yes, we offer premium flexo printing with up to 8 colors. We support full customization for size, printing, and material specifications to meet your branding needs.

Q:How do you ensure the bags are moisture-proof and leak-proof?

We offer PE lamination or an inner PE liner to provide excellent moisture resistance. Combined with precise hot-melt sealing at the valve, it effectively prevents powder leakage.

Our standard production lead time is typically 15-20 days after order confirmation. Rush orders can be accommodated upon request.
