Regardless of the external factors, everyone has different hobbies in terms of design, bag type, etc. Today, let’s talk about the internal parts of customized food packaging bags. As the external packaging of food, the main thing is to ensure the quality of food in the bag. What should be paid attention to when customizing food packaging bags? Now let’s get to know.

1、 Strength request:

It refers to that during the process of storage, stacking, transportation, and handling, the package can protect the packaged food from various external destructive forces, such as impact and vibration under pressure. Different transportation methods, different storage and handling methods, and different storage environments have different requirements for packaging strength.

2、 Barrier Request:

Barrier is one of the important properties of food packaging bags. During the storage and packaging of many foods, the flavor and quality of food will change due to poor barrier performance, which will affect the quality of food. Barrier requests are determined by the characteristics of the food itself, and are expressed as external barriers, internal barriers or selective barriers. Barrier materials include air, water, grease, light, microorganisms, etc.

3、 Breathing request:

Some novel fruits, vegetables and other foods still adhere to the respiratory function during packaging and storage. Therefore, the materials of the packaging bag should be breathable to achieve the purpose of fresh-keeping.

4、 Nutrition request:

Food will gradually lose its nutrition during packaging and storage. Packaging bags should play the role of keeping food nutrition, and it is more ideal that nutrition can be locked through packaging. Other requirements: Food packaging has many inherent requirements, such as heat resistance, light resistance, shatter resistance, moisture retention, etc.

The above is the explanation of the precautions when customizing food packaging bags. After reading, do you know? I hope it will be helpful to you.
