A secure beef jerky bag protects beef jerky from oxygen, dirt, and insects during transport and storage. Following are two most essential qualities of a secure beef jerky bag.

(1) Protection from oxygen

Oxygen is the mortal enemy of beef jerky, therefore the most important quality of a secure beef jerky stand up bag is the ability to protect jerky from oxygen. There are several methods to do that. A common and effective method is to use vacuum packaging. Beef jerky is vacuum packaged to deprive the bacteria of oxygen. The only problem with this method is that it makes the packet looks crumpled. This is why many manufacturers prefer oxygen absorbers. These small packets absorb oxygen and keep the jerky safe.

(2) Protection from dirt and insects

Beef jerky bags are essentially stand up pouches. They are made by laminating together several polymer layers. This multiple layer structure makes an effective barrier against dirt. The materials used in pouch bag layers make them puncture resistant. These puncture-resistant pouch bags are strong enough to stand against the attack of insects. In other words these insects cannot bore their way to beef jerky through the pouches.

Due to these qualities, standup pouches are the best packaging medium for jerky.
