The Protein Shake Pouch for EZY Pro 10 is re-closable, super lightweight stand up pouch made by Ampac Flexibles. This pouch incorporates a 21mm spout and tamper evidence cap which contains 33 grams of functional food concentrate which is mixed with water inside the pack. The consumer simply fills the shaped pouch with 230ml of water, measured by a special mark on the pack. It is then shaken to mix the concentrate and enjoyed directly from the pouch. Drinking is very convenient due to presence of the spout’s wide diameter and, of course, the pouch can be reclosed.
