1. barrier is one of the important features of food packaging design. When many foods are stored, the flavor and quality of food are changed due to the poor barrier design of packaging, which ultimately affects the quality of food. The barrier requirements of packaging design depend on the nature of food itself, which is manifested as external barrier, internal barrier or selective barrier. The blocking substances are air, water, grease, light, microorganisms and so on.
2. Some exported foods, such as fresh fruits and vegetables, still keep breathing function during packaging design and storage. Therefore, this packaging design material or container is breathable or can control breathing to achieve the purpose of preservation.
3. In the process of packaging and storage, food will gradually lose its nutrition. Therefore, food packaging design should be conducive to the preservation of food nutrition, but also need to lock nutrition through packaging design.
4. Food packaging design has many inherent requirements, such as heat resistance, light protection, shatterproof, moisture retention and so on.
Extended data:
Food packaging can be divided into metal, glass, paper, plastic and composite materials. According to the packaging type, it can be divided into cans, bottles, bags, rolls, boxes, boxes and so on. , and can be divided into cans, bottles, envelopes, bags, bags, pour, whole set, sealing, labeling, code spraying, etc. According to the way of packing. According to the product grade, it can be divided into internal packaging, secondary packaging and tertiary packaging.
There are many ways to classify food packaging. For example, it can be divided into moisture-proof packaging, waterproof packaging, mildew-proof packaging, fresh-keeping packaging, quick-frozen packaging, breathable packaging, microwave sterilization packaging, aseptic packaging, inflatable packaging, vacuum packaging, deoxidation packaging, blister packaging, body shaping packaging, stretch packaging, retort pouch packaging and so on.
The above packaging is made of different composite materials, and its packaging characteristics meet the requirements of different foods, which can effectively protect the quality of food.
Aseptic packaging occupies a large proportion in food packaging. For example, aseptic milk packaged in small bags is cheaper, has better flavor and can be stored for a long time at room temperature. Manufacturers and consumers welcome this kind of packaging product, which not only overcomes the limitation of production area, but also eliminates the cold chain needed in transportation, which is conducive to the expansion of the market.
