澳大利亚采购需求：自立袋，自立袋制造商，自立袋，铝箔袋，卷膜，牛皮纸袋

I'm looking for a supplier who can pack roasted coffee beans in three different sizes: 250g, 500g, and 1kg. It's important that the packaging not only preserves the freshness but also appeals visually to our target market. I would like to know what options you have available in terms of materials and designs that fit these specifications. Additionally, it would be helpful to understand your pricing structure, lead times for production, and any minimum order quantities that apply. If you have samples or catalogs of your previous work, please share those as well. I'm excited to see what you can offer and hope we can establish a mutually beneficial partnership. Looking forward to your prompt reply!
