Stand up pouches like barrier bags are made by lamination of multiple layers of film that give a lot of strength and durability to the packaging. Having many layers joined together, these bags are puncture resistant and tear proof. Protecting granola from moisture, oxygen, odor, vapor, direct sunlight, and ultraviolet rays, these bags prove to be reliable custodians of quality.
Standup granola packaging is popular not only because it provides protection to granola and keeps it fresh, but also because it offers many colors, layout, and design choices. This is how they prove to be the showstoppers in most stores. Their tear notches, hanging holes, and zip locks etc. add extra features. Additionally, the calorie-count scripted on stand up bags provides the information about the calorie intake with each granola serving.
