塞拉利昂采购需求：自立袋、包装、可重复密封袋、食品储存、拉链袋、软包装

I'm looking to explore options for customizing stand-up bags in various sizes and colors. Please provide me with information about the materials you offer, as well as any available printing options for branding. It would be great if you could include details on minimum order quantities, lead times, and any bulk pricing discounts. Additionally, I'm interested in knowing if you have any sample designs or existing color palettes to help visualize the possibilities. Understanding the durability and eco-friendliness of the materials would also be beneficial. Looking forward to your prompt response so we can move forward!
