Firstly, the corner spout pouch can be divided into two styles that appear almost identical. The difference lies in the "corner spout." The peak point of spout cap #1 is almost parallel to the level of the pouch top, while the peak point of spout cap #2 is lower than the level of the pouch top by at least 2cm.

Secondly, the filling and sealing place of the stand up pouch with corner spout also differs. In style #1, the packaging content is filled through the spout and then locked by torque power. In contrast, in style #2, the packaging content is filled through the pouch top and then heat-sealed using a mould.

Lastly, the packaging function of these two styles also varies. Style #1 is limited to liquid or semi-liquid products and requires a spout pouch filling and capping machine. On the other hand, style #2 is suitable for liquid, semi-liquid, powder, granules, and other products, and requires a premade pouch packaging machine.

It is essential to understand these differences when adopting the corner spout pouch as a new packaging presentation. Selecting the appropriate packaging machine can save time and improve efficiency. In conclusion, the corner spout pouch is a versatile packaging style that offers multiple functions, but it is crucial to choose the right style and packaging machine for your product.
