There are two main types of corner spout doy pack bags, distinguished by the filling place. The first type is filled from the pouch top, and has a non-equilateral triangle corner spout angle. This type is matched with a non-step spout cap, which is pre-locked together with the pouch. The second type is filled from the spout, and has an equilateral triangle corner spout angle. This type is matched with a single or double gap spout cap, and does not allow for pre-locking.

The maximum filling space for corner spout doy pack depends on the spout level. For the type filled from the pouch top, the max filling space is 50%-60%, as the spout level is located at the middle of the doy pack stand up pouches. For the type filled from the spout, the max filling space can be up to 70%, as the spout level is located at the upper middle of the pouch.

In conclusion, corner spout doy pack bags are a versatile packaging option for a variety of products. Their unique design and different filling options allow for efficient and effective packaging solutions.
