Can Kraft Stand Up Pouches Be Recycled? A stand up pouch made from kraft material that is laminated to other layers of film IS recyclable and landfill friendly. To be clear, kraft — once it is laminated — is NOT biodegradable, but it is recyclable. There are many good reasons why these pouches are not biodegradable, and they have to do with how well the product inside is protected. 100% Recyclable Stand Up Pouch To biodegrade, packaging has to be able to break down when exposed to light and air. However, one of the biggest advantages of using kraft stand up pouches for product packaging is that their laminated layers of barrier film and opaque finish block out light and air, which extends the shelf life of food and protects it from spoilage or contact with harmful outside contaminants. This is the difference between your standard brown paper bag and a kraft stand up pouch. You wouldn’t expect food in a paper lunch bag to stay fresh at room temperature for an entire week. But in a food-grade, FDA-approved, reclosable kraft stand up pouch, food products will stay fresh because air, moisture, light, and pests are locked out for an extended period of time.
