Two different handle of corner spout stand up pouch

The first type of handle is the punched handle, which is a traditional handle punched by a customized mold and assembled on the pouch making machine. Its advantage is that it does not add any extra cost to the spout stand up pouch. However, it can only withstand a maximum weight of 3KG, and the stress points of this handle are concentrated. This can lead to hand fatigue if the spout stand up pouch needs to be carried for an extended period of time.

The second type of handle is the injection handle, which is a newer style handle made by an injection machine and manually embedded inside the punched hole. Its advantage is that it is sturdy and provides a perfect hand feeling, as the stress points are dispersed. However, it significantly increases the cost of the corner spout pouch.

In my experience, I would recommend the second handle. This recommendation is not based on any technical reasons, but rather on the preference of my wife and daughter. They have expressed a liking for and have often selected this kind of handle when purchasing liquid detergent from the supermarket.

In conclusion, both types of handles have their own advantages and disadvantages. While the punched handle is cost-effective, it may lead to hand fatigue, especially when carrying heavier loads. On the other hand, the injection handle provides a more comfortable grip but comes with a higher cost. Ultimately, the choice of handle will depend on the specific needs and preferences of the consumers and the industry.
