Our requirements when designing food packaging bags refer to the technical requirements for ensuring the quality of food in its packaging design through packaging. Today we will explain:
1. Design strength requirements: It means that the packaging design can protect the packaged food against various external destructive forces during storage, stacking, transportation, and handling, such as pressure, impact, and vibration. There are many factors related to the design strength requirements of food packaging bags, mainly including three types of factors: transportation mode, stacking form and environment.
2. Barrier property requirements: Barrier property is one of the most important properties in food packaging design. When many foods are stored, the flavor and quality of the food will change due to the poor barrier properties of the packaging design, which will eventually affect the quality of the food. The barrier requirements of packaging design are determined by the characteristics of the food itself, and its characteristics include external barrier, internal barrier or selective barrier and so on. The blocking substances include air, water, grease, light, microorganisms and so on.
3. Design breathing requirements: Some exported foods such as fresh fruits and vegetables still maintain breathing function during packaging and storage. Therefore, such packaging materials or containers have air permeability, or can control respiration, so as to achieve the purpose of keeping fresh .
4. Nutritional requirements: Food will gradually lose nutrition during packaging and storage, so the packaging design of food packaging bags should be conducive to the preservation of food nutrition, and it is more ideal to lock nutrition through packaging design.
5. Other requirements: There are many inherent requirements for the design of food packaging bags, such as heat resistance requirements, light protection requirements, moisture retention requirements, etc. Vacuum packaging bag Tea packaging bag Composite packaging bag Aluminum foil bag Plastic packaging bag
