Please briefly describe: the characteristics and manifestations of food packaging in China. You can write relevant information and website. Urgent need, thank you! ! !

China people's outstanding feature in gift packaging is the use of auspicious patterns. On the gift packages of traditional festivals such as Spring Festival and Mid-Autumn Festival, you can often see the patterns of "the Goddess Chang'e flying to the moon" and "Four Happy Days". On the gift packaging of blessings and birthdays, we can often find patterns such as "turtle crane" meaning "longevity", "heaven and earth" symbolizing "longevity", "fish" symbolizing "surplus" and "peony" symbolizing "wealth". China's traditional patterns are rich and colorful, usually taking natural images or traditional stories as the theme, and expressing people's beautiful life with implicit metaphors such as implication, symbol, borrowing and analogy.

Take cake gift packaging as an example. At present, there are mainly:

1, color printing plastic film packaging: this is the mainstream of pastry packaging, which has several characteristics: ① exquisite color printing and attractive luster can beautify the display of shelves and induce people to buy. This is mainly due to the advanced color printing technology, which makes the printed color printing film have super-value aesthetic effect, more real, more observable and more attractive than the contents. (2) Convenient to eat: it is convenient to tear open, which is also an advantage of color printing plastic film packaging. As a snack food for children and women, this packaging form is very popular. (2) Keep it clean and prevent pollution. A bag can give people a sense of safety and hygiene. Therefore, this kind of packaging has always been a form that manufacturers and consumers are willing to accept, but the fly in the ointment is that packaging is difficult to degrade, which is easy to form "white" pollution, which is not conducive to environmental protection.

2. Packaging of paper products: Due to the advanced, safe and fast color printing plastic film packaging, it has had a great impact on the packaging of paper products, making the packaging of paper products change from the dominant position in the past to the subordinate position and maintain its own place in its own unique field. This unique field includes three aspects: ① Outer packaging box (box), color printing plastic film can not be replaced, because outer packaging box as a paper product has the functions of transportation, storage, placement and carrying, as well as beautiful printing effect. Therefore, the packaging of paper products still plays an important role in pastry food. (2) High-grade pastry gift boxes must also be designed and printed with paper products, so as to upgrade the grade, reflect the nobility of social status and complete artistic reproduction. Have you noticed that on the occasion of the Mid-Autumn Festival, the mooncake gift boxes in major shopping malls and supermarkets are resplendent, elegant, unique and exquisite, all made of paper products. From this point of view, no metal plastic or other packaging products can replace the universal advantages of paper products. ② Low-grade simple ordinary cake packaging. For the sake of hygiene and convenience, this kind of packaging usually has a simple small paper box, a simple piece of paper, a simple pattern printed casually, or no pattern printed, a cake wrapped up, picked up and left, as simple as that. This kind of packaging can be seen in rural street stalls or shopping malls with low consumption level, and there is still a certain market space.

3. Packaging of craft ornaments: This kind of packaging has gradually flourished in recent years with the development of economy, the improvement of people's living standards and the change of cultural needs. Its scope, in addition to handicrafts such as drinks, is also a prominent highlight in the pastry category. Especially during the Mid-Autumn Festival, as long as you are near the food store, it is not difficult to see all kinds of craft decorations packed with plastic products, bamboo products, paper products, wood products and iron products, such as pagoda, temple of heaven, dragon boat, pavilion, bell, horse, the Goddess Chang'e flying to the moon and so on. It is convenient for people to keep a handicraft to watch after using cakes. This kind of packaging form, it should be said, is also a new family, a manifestation of culture and taste, and also a challenge and opportunity for packaging and decoration designers.

4. Packaging of plastics and other products. This kind of packaging of plastic products refers to a kind of plastic products (such as gift boxes) which can be distinguished from color printing films, transparent and opaque plastic packaging products, and plastic boxes which are packaged with hard plastic products and lined with brackets after printing and other processes. This kind of packaging fills the field of packaging products in many ways and has the potential for growth. As other products, it mainly refers to some packaging products that are not commonly used but sometimes appear, such as tin products packaging, bamboo weaving, straw weaving technology packaging, wood products packaging, lotus root leaves, corn leaves and other packaging materials (like zongzi, which has been completed by brown leaves for many years). These packages are mainly influenced and restricted by resource conditions and specific folk culture. They are not the mainstream of pastry packaging, but they have played a positive role in green food, environmental protection, returning to nature, improving artistic taste and enriching packaging forms, and have great potential to be tapped.
