葡萄牙采购需求：聚乳酸、PLA、聚己内酯、PCL、乳酸酯、乳酸乙酯

I'm interested in sourcing Coated Grade PLA for my upcoming projects. Could you provide me with the price per kilogram for this material? Additionally, I'd like to know if you have any minimum order quantities or bulk purchase discounts available. My location is Minho-Lima in Portugal, so please include shipping details and estimated delivery timelines as well. Looking forward to your prompt response!
