马拉维采购需求：空茶包、滤茶包、散叶茶包、泡茶包、空白茶包、一次性茶包

I'm looking for detailed information regarding a specific type of filter paper. Please provide the specifications including the dimensions and any available options for patterned tea paper. I'm particularly interested in the core size and the outer diameter. Additionally, it would be great if you could include your pricing information, minimum order quantities, and lead times. Any insights on the material composition and suitability for various applications would also be appreciated. Thank you!
