At present, the packaging of candy and chocolate products has three main functions. First, it can protect the luster, fragrance and shape of the product and extend the shelf life. Second, it can prevent microbial and dust pollution and improve the hygiene and safety of products; Third, exquisite product packaging can improve consumers' desire to buy and the value of goods. Therefore, packaging plays an important role in the quality, hygiene and shelf life of candy and chocolate products. Good products must have exquisite and beautiful packaging. At present, the packaging forms of candy and chocolate products in China are kink packaging, pillow packaging and folding (envelope) packaging. Traditional kink packaging is the oldest packaging form, which is mostly used for candy. It can be completed not only by modern high-speed automatic packaging machine, but also by manual operation. Pillow packaging became popular in the 1960s and 1970s internationally, and became popular in China in 1980s. Due to the popularity of pillow packaging machines, most candy and chocolate manufacturers now adopt pillow packaging and folding (envelope) packaging, which are mostly used for chocolate products. Candy is suitable for roll package, strip package and packaging. This form of packaging requires higher packaging equipment and packaging materials. Compared with developed countries, there is still a big gap in the packaging level of candy and chocolate products in China. The main problems are the low level of packaging equipment, few types of packaging materials and poor quality.
The only way to quickly shorten the gap between domestic candy chocolate products and developed countries is to take the road of technological innovation. In the future, the development trend of domestic candy and chocolate packaging is bound to be the development of high-speed automation, multi-function and characteristic packaging design of packaging machines. First of all, candy and chocolate manufacturers generally need high-speed and automatic packaging machines when packaging standardized products, in order to pursue the optimization of packaging costs under economies of scale. Therefore, in recent years, packaging machine manufacturers have developed high-speed and automatic packaging machines suitable for different types of products, such as traditional pillow packaging and some kink packaging machines suitable for double kink products. In this kind of packaging machine, the manufacturer adopts the latest technology, such as full servo motor, photoelectric tracking, high-speed camera and so on. In order to achieve the efficiency of packaging machine. At present, there are 1500-2000 high-speed pillow hard candy packaging machines every minute. High-speed pillow chocolate packaging machine is developed from the aspects of equipment matching with cold air packaging film, and it can achieve high speed without affecting the quality of internal chocolate products. In addition, the functions of automatic turning, sorting, emergency stop and acceleration of the conveyor belt connected with the chocolate packaging machine are also widely used. Secondly, for non-standardized or seasonal products, the packaging machine should be flexible and characterized by portability and compactness. This kind of packaging machine does not pursue speed, but pursues personalized packaging and flexibility. In addition, in order to adapt to the competition of commodities, the original packaging design constantly strives for novelty and novelty, giving people a strong visual impact. For example, the bottled xylitol chewing gum on the market at present is very popular because the packaging improvement is suitable for the consumption psychology of the younger generation.
