英国采购需求：食品拉链袋、塑料拉链袋、拉链袋

I'm looking to place an order for custom-printed mini PE ziplock bags in six unique designs. The details are as follows: I need transparent LDPE bags with a small ziplock/ grip seal, featuring a one-color red logo printed on one side. The total order is for 6,000 bags, with 1,000 pieces for each of the six designs in various sizes, including options ranging from small to medium. Please provide unit pricing for each size, including any setup or plate charges for the designs. Don't forget to factor in DDP shipping to Northern Ireland, covering all customs duties and import VAT. I'd also like to know your lead time for production plus shipping, and whether you do digital or screen printing for these quantities. Looking forward to your best quote!
