When is the volume coefficient of square foot valve pocket suitable for use?

The volume coefficient of the square bottom valve pocket is 85% - 95%, which is suitable for use. If it is lower than 85%, it will cause difficulty in handling. If the valve port is not closed tightly, it will cause material leakage. If it is higher than 95%, it will cause the bag body to roll round after filling, and it will be difficult to stack.
