I'm looking for standing detergent pouches available in 1L, 3L, and 5L capacities, specifically designed with a large spout for easy pouring. It's essential that these pouches are durable and suitable for liquid detergent to ensure they can withstand handling and storage without leaking or tearing. Additionally, I'd appreciate some information on your available options, including material specifications, customization features, and the minimum order quantities. If you have any samples or previous projects that showcase your work with similar products, please include that as well. Looking forward to your response!
