The packaging industry is a mass market industry, and its applications can be seen in many fields. When it comes to packaging production and manufacturing, ultrasonic welding technology cannot be ignored. Ultrasonic welding technology is an ideal choice for sealed packaging, as the weld seam is air and water tight and can even be processed to contaminated areas such as grease, liquids, fibers, or powders.

Another advantage of ultrasonic sealing is that it does not require adhesives or solvents, which means specific types of recycling can be carried out and some cleaning steps can be eliminated. Ultrasonic technology is very environmentally friendly, as the welding or stamping process is short and the energy consumption is relatively low. So, very thin packaging materials can be used, which has many economic and ecological benefits for packaging production.

Ultrasonic waves can be used alone or in combination to weld different materials, such as the familiar PP material, PVC，PE，PET， Composite materials, films, and non-woven materials require long-term and high-quality welding, as ultrasonic waves achieve visually appealing and durable welding effects. Due to the fact that the tools in ultrasonic welding technology generate high temperatures instantly, they are very suitable for packaging thermal sensitive items. The advantage of "cold" welding is that it will not cause any damage to the packaging materials when the machine starts and stops.

1. Shell and top cover

The sealing of top cover film, welding of sealing rings, and packaging sealing of filters are several important applications that can be solved using ultrasonic welding machines. Welding molds can ensure durability and protect product quality by positioning thin films without the need for heating.

2. Film packaging

Residual products in the weld area can be safely separated through ultrasonic waves to ensure absolute sealing, which can significantly reduce the number of packaging leaks and enhance the durability of the product. The ultrasonic welding machine fully demonstrates this advantage in longitudinal continuous welding and transverse intermittent welding of hose bags, zipper bags, and self-supporting bags.

3. Packaging of PET materials

When PET materials in the packaging industry are welded with ultrasonic waves, they can quickly reach a high melting point and increase production. They can also achieve sealing and separation of the blister, as well as easy opening and anti-counterfeiting functions for genuine products.

4. Beverage flexible packaging

The packaging of soft drinks can be seen everywhere in daily life. Ultrasonic welding machine is particularly suitable for cardboard packaging materials with coatings, which can ensure the sealing of the weld seam. Whether there is aluminum film or not will not affect the welding. The sealing time is relatively short, and the output is also high. The repeatable welding parameters can ensure the consistency of sealing quality.
