Center seam cutting is a common bag manufacturing method, referring to a precise cut made along the center side seam between the front and back of the bag.

The core objectives of this process are:

1. To create a filling/filling port: Providing a convenient and unobstructed entry point for high-speed filling of powders, granules, and other materials.

2. To improve ease of use: Allowing consumers or equipment to easily open the packaging along the pre-set cut.

3. Its characteristics include high processing efficiency and cost-effectiveness, and it is widely used in stand-up pouches, three-side seal bags, and other packaging in the food and daily chemical industries.
