Although the outer packaging design of pet food has a great impact on sales, as a packaging bag, its performance is the basis. JMei Packaging has been focusing on the customization of composite flexible packaging for more than 15 years and has rich experience. Below, I will introduce some basic performances that need to be paid attention to in the customization of pet food packaging bags.

In addition to the basic mechanical properties, including puncture resistance and drop resistance, it is also necessary to pay attention to the customized barrier properties of pet food packaging bags, including oxygen permeability and water permeability.

1.Oxygen permeability

The oxygen barrier performance is stronger, because many pet foods have a large amount of meat added, and the fat content is high, which will be oxidized and deteriorated, and if the barrier property is poor during the storage process, the smell will be released, which will reduce the user’s satisfaction with the product .

2.Water permeability

If there is no good water blocking ability, especially for granules or freeze-dried pet food, it is easy to suffer from moisture and deterioration, and more seriously, it may lead to the proliferation of pet food microorganisms and affect the health of pet food.
