Drink packaging is not limited to just sodas and juices. Various other products like mocktails and squashes are also available in stand up bags. They are easier to drink from spouted pouches, and the empty packs can be disposed off easily. Also, since these bags are really inexpensive, small quantities can be packed and distributed for promotional schemes and offers.
A juice pouch is a very useful application of such bags. Manufacturers can add small holes for straws or provide a notch for tearing off the packet. This makes the juice pouch handier. Spouts with caps can also be added which makes the product re-usable. In most cases, these pouches provide longer shelf life. This is because of the multi layered barrier packaging that keeps the contents safe.
Almost any food product can be packaged in standup bags. By tweaking a bit on their styles, different types of packaging can be done for different types of foods and drinks.
