Croutons are great as snacks, and they can also be added to salads for a yummy delight. They mostly come in plastic pouches that are made carefully to keep their freshness locked in.

What are crouton bags made of?
These bags are usually made by combining several laminate layers together so that the packet gets extra durability. These bags act as a barrier for external factors, so they are also called barrier bags. They protect the contents from moisture and air.

These bags are made of FDA approved food grade material so that it does not react with the food packaged inside. There are different types of barrier bags and they all have one main purpose- to protect its contents.

There are multiple layers of the bag, and each one has a different role to play. These layers are transparent and the function of the outermost layer is to keep air, sun, moisture, and germs outside. This layer can also be used to apply colored ink for display purposes. In some cases (for example, if you want to add a window to the pouch), the outer layer is left as it is, and the ink is applied to the middle layer.

The innermost layer is always made of food grade plastic as it comes in contact with the croutons. This layer does not contain any ink and it keeps the contents safe.

The advantage of using barrier bags is that they are strong and durable, and can handle rough handling. They are scratch resistant, and do not break or crack easily.

Barrier bags keep croutons fresh. However, if you want, you can use the method of nitrogen flushing to make sure they stay completely moisture free, and crisp and crunchy. Nitrogen flushing is a method by which the oxygen of the packet is pushed out and nitrogen is filled there. As oxygen is responsible for the rotting of food, it is a good idea to flush the packets with nitrogen.

Snack packaging relies heavily on standup bags. These bags offer many options that other packaging solutions don’t offer. Of course there are simple plastic pouches, but they are not efficient in providing tear resistance. With multiple layers, these pouches can be shipped to different locations without any wastage.
