Yogurt, with its unique health, slimming effect and successful entertainment marketing, has quickly become popular among young people. In recent years, yogurt is popular with the improvement of living standards and health awareness in China.Data show that in 2019 China's dairy sales reached 419.6 billion, of which yogurt accounted for the highest 36%.

Statistics show that Chinese normal temperature yogurt market sales in 2018 were about 38 billion yuan, a year-on-year increase of 52%, and it is expected to continue to expand in 2020.

Yogurt sales are increasing year by year, there is a huge market behind-yogurt packaging. As consumers pay more and more attention to the design of food packaging, businesses also require product packaging to be unique and create product selling points. Therefore, the use of in-mold labeling yogurt cups is becoming more and more widely, thus improving the in-mold labeling machinery Demand.

In-mold labeling technology has been used in food packaging such as yogurt cups as early as a decade ago. In recent years,  the production and sales of in-mold yogurt cups have exploded，because the reduction of equipment production costs and the improvement of product yields. At the same time, due to the strong market demand, the application of new processes and technologies has further improved the production efficiency and stability of the new generation of in-mold systems. Switek new-generation in-mold labeling system has achieved a major breakthrough in in-mold time and label replenishment methods compared to the previous generation.

A Switek designer said, because the electronic control part of the new system adopts a new communication method, the controller can continuously modify the operation command according to the parameters returned by the servo motor, so as to obtain higher efficiency. Therefore, the optimized in-mold labeling system of the new yogurt cup can reduce the in-mold time to about 0.9 seconds. With the high-speed injection molding machine, the entire production cycle is shortened to 2.8 seconds.

Another major improvement of the new in-mold labeling system is its design of the label warehouse. According to the previous design plan, when a warehouse has run out of labels, it needs to be shut down and manually refill the warehouse to restart the machine. The new system adopts the improved standard warehouse design, which can realize the warehouse replenishment operation with non-stop, which saves the downtime of replenishing the label effectively.
