Stand Up Bag Solutions

One of the core design aspects of stand-up pouches is delivering a high barrier for product preservation. The barrier is also supposed to keep the product from leaking while the pouch is being handled or is in transit. As such, it is safe to say that a stand-up pouch is only as good as its sealing.
There are different ways to seal a stand-up pouch. It all comes down to what is in the bag, the available machinery, and the material of the pouch. Below we look at some of these sealing methods as well as their pros, cons, and how to choose the right one.
Heat sealing is arguably the most common method used to seal stand-up pouches. It is used in multiple stages too. The first is during the bonding of the multiple layers of stand-up pouches. The second is when the pouch is filled with product and its main opening needs to be sealed to keep the product safe.
The concept of heat sealing involves the application of heat on the surface where a stand-up pouch is to be sealed. This causes the two layers of material on either side of the opening of the pouch to slightly melt and bond. The bonding of the layers is done under controlled temperatures which do not damage the appearance or performance of the stand-up pouch. There are also no chemicals added during the process.
