Flat coffee filter bags can be sealed using a regular household heat-sealing machine, making them suitable for businesses or individuals who prepare their own powdered ingredients. They are ideal for cold brew coffee or immersion brewing methods. Immersion brewing produces coffee with a rich aftertaste, and the key to adjusting coffee strength lies in the coffee-to-water ratio and the immersion time. This method is easy to adjust, produces consistent coffee flavor, and requires no complex steps or advanced pouring techniques. Even beginners can easily master it. Simply maintain the fixed coffee-to-water ratio, water temperature, and immersion time to easily batch-produce coffee with stable quality. We also offer coffee filter bags with strings and tags or raw materials.
