Nowadays, packaging is becoming increasingly important in the food, beverage, retail and pharmaceutical industries. A good packaging can not only protect products from damage and increase shelf life, but also a better packaging appearance can attract attention faster in front of consumers. Therefore, the quality of packaging is very important for consumers to evaluate the value of goods.
Traditionally, high temperature packaging is a commonly used packaging method for packaging products because of its low investment cost and easy to master mature technology. However, with the development of technology, ultrasonic welding technology has been widely used in the market in recent years because of its quality advantages over traditional heating methods. That is the ultrasonic packaging machine.
The principle of ultrasonic packaging equipment
The basic principle of the ultrasonic packaging technology is using the sonic tool vibration energy, ultrasonic longitudinal vibration will contact with the area of thermoplastics directly through the ultrasonic horn, and produce tens of thousands of times of the high frequency vibration per second. Because the acoustic resistance of the two welding contact surface area is larger, which can produce local high temperature. And because of the poor thermal conductivity of the plastic, the heat does not easily diffuse and accumulate in the welding area, causing the plastic to melt. In this way, under the action of continuous contact pressure, the welding contact surface is integrated, so as to achieve the purpose of welding. The process of melting materials do not need the use of expensive and easily contaminated auxiliary products such as adhesives, nails or adhesives has brought many benefits to the packaging industry.
The advantages of ultrasonic packaging equipment
1. Good sealing
If the welding Joint is as firm as raw material, the product can be better protected. We don not need to worry about food leakage and preservation. The typical applications is welding joints for milk and juice.
2.No need to preheat, maintain constant temperature
Ultrasonic welding process will not generate excess heat, which is especially important in food packaging. It means that for temperature-sensitive products, such as food and drinks, the inside of the package will not be affected. It can helps to preserve food better. The typical applications include packaging bags.
3.Clean and eco-friendly
During the welding process, there is no contaminants. Internal products will not be contaminated. In addition, processed food packaging products are environmentally friendly and reproducible, and there is no need to use expensive and pollution-prone auxiliary products in the processing process, which reduce operating cost and save a lot of heat energy.
If you are interested in the ultrasonic packaging machine, please kindly let us know, we can recommend suitable welder based on your products and welding requirement; As an enterprise with independent research and development ability, we can also customize the welder for you based on your requirement.
