What should we pay attention to in food packaging ?
The inherent requirements of food packaging design: the inherent requirements of food packaging design refer to the technical requirements of ensuring quality and quantity of food in its packaging design through packaging.
Strength requirement of food packaging design: It means that the packaging design can protect the packaged food against various external destructive forces such as pressure, impact force and vibration force during storage, stacking, transportation and handling. There are many factors related to the strength of food packaging design, such as transportation mode (such as automobile, aircraft), stacking form (such as multi-layer stacking, cross stacking) and environment (such as climate, sanitary environment).
Food packaging design barrier requirements: barrier is one of the important properties in food packaging design. When many foods are stored, the poor barrier of packaging design changes the flavor and quality of food, and ultimately affects the quality of food. The barrier requirements of packaging design are determined by the characteristics of food itself, which are characterized by external barrier, internal barrier or selective barrier, etc. The barriers are air, water, grease, light, microorganisms and so on.
Respiratory requirements for food packaging design: Some distant foods such as fresh fruits and vegetables still keep breathing function in the process of packaging design and storage. Therefore, such packaging design materials or containers have breathability, or can control breathing, so as to achieve the purpose of preservation.
Nutritional requirements of food packaging design: food will gradually lose nutrition in the process of packaging and storage. Therefore, food packaging design should be conducive to the preservation of food nutrition, and more ideally, it can lock nutrition through packaging design.
Other requirements: There are many inherent requirements in food packaging design, such as heat resistance requirements, light protection requirements, shatterproof requirements, moisturizing requirements, etc.
External requirements of food packaging design: The external requirements of food packaging design are to use packaging to reflect the characteristics, performance and image of food, and it is the external visualization and expression form and means of food.
Safety requirements of food packaging design: Safety of food packaging design includes hygiene safety, handling safety and use safety. Hygienic safety means that food packaging materials should not contain harmful substances to human body. In packaging design technology, the nutrient composition, color and taste of processed food should remain unchanged as far as possible. Handling safety refers to the packaging design that can ensure the safety in the process of transportation, loading and unloading. It should also include the safety of consumers when they are shopping and after they are purchased. Safety of use is to ensure that consumers are not harmed in the process of opening and eating.
Promotional requirements of food packaging design: Food packaging design is one of the best means of food promotion. The properties, characteristics, eating methods, nutritional components and cultural connotations of food can be propagated in packaging.
