萨尔瓦多采购需求：塑料袋、食品袋、咖啡袋、茶包、过滤咖啡

I'm interested in sourcing coffee bags and would like to explore your product offerings. Specifically, I'm looking for high-quality options that can effectively preserve the freshness and flavor of the coffee. It would be great if you could provide information on the materials used, available sizes, and any customization options. Additionally, I'm curious about your minimum order quantities and lead times for production. If you have any samples available, that would be helpful for evaluation. Please also share your pricing structure, including any bulk order discounts. Looking forward to your detailed response!
