澳大利亚采购需求：小袋和收纳袋，小袋和收纳袋，拉链自立袋

I am looking for high-quality stand-up pouches with large side spouts. Specifically, I need options for two sizes: one for 750ml and another for 1 liter. It's important that these pouches feature a small preview window, as they will be used for ready-made gravy products. The aesthetic is crucial, so I'm particularly interested in a matte black finish that can effectively showcase our branding with printed logos. In addition to the dimensions and design features mentioned, please provide details on the material options available. I want to ensure durability and usability for our target market. Also, include information on minimum order quantities and lead times for production. It would be great if you could send over samples or images of similar products you've manufactured in the past. Looking forward to your prompt response!
