美国采购需求：咖啡袋，扁平袋

I'm interested in one of your bags and would like to know its specific dimensions. I'm looking for a bag that can comfortably hold 200 grams of roasted coffee beans. Understanding the size will help me determine if it meets my needs for packaging and storage. Additionally, if you could provide any details about the bag's features, such as material and durability, that would be great. This will help me evaluate its suitability for my product. Thanks for your assistance!
