What are the requirements for food packaging?
Intrinsic requirements for food packaging design: The inherent requirements of food packaging design refer to the technical requirements for packaging to ensure the quality and quantity of food in its packaging design.
Food packaging design strength requirements: This 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 related factors in the design of food packaging design strength, mainly including transportation methods (such as cars, airplanes), stacking forms (such as multi-layer stacking, cross-stacking) and environment (such as climate, sanitation environment).
Food packaging design barrier requirements: Barrier properties are one of the important properties in food packaging design. When many foods are stored, the flavor and quality of the food change due to poor barrier design of the packaging, which ultimately affects the quality of the food. Packaging design barrier requirements are determined by the nature of the food itself, characterized by external barriers, internal barriers or selective barriers. Barrier substances are air, water, grease, light, microorganisms, etc.
Food packaging design Respiratory requirements: Some exported foods such as fresh fruits and vegetables, etc., still maintain respiratory function during packaging design storage. Therefore, such packaging design materials or containers are breathable or can control respiration to achieve preservation.
Nutritional requirements for food packaging design: Foods will gradually lose nutrition during packaging and storage. Therefore, food packaging design should be conducive to the preservation of food nutrition. Ideally, the packaging can be designed to lock nutrition.
