Packaging

The ultrasonic technique can be used without preheating, and the ultrasonic welding process is very fast and stable. The ultrasonic welding module works with the production line of automation equipment and performs automatic welding under computer control, which saves labor, consumables, and the like.

Application Advantages

Ultrasonic welding is demonstrating increasingly clear advantages in the packaging industry. Packaging materials are sealed after being heated under ultrasonic vibration at a high frequency of 20~40 kHz, which demonstrates a pretty clear advantage in sealing compared with thinner or thicker packaging materials. It not only shortens the welding time and improves efficiency, but also saves energy and packaging materials.

Ultrasonic welding & sealing: food packaging, medical packaging, valve bag packaging, PE packaging, FS packaging, nonwoven packaging, leather packaging, composite film packaging, and so forth.

Without heating elements, each package solely consumes 0.1s electric energy; without preheating time, the time it takes to seal materials is short; the excellent performance in sealing contaminants allows products previously canned or bottled to be packaged flexibly.

Ultrasonic Welding Advantages

* Ultrasonic welding performs well in sealing without any flux. It is applicable to milk and juice packaging bags;
* Efficiency is improved and costs are reduced. The time it takes to weld is so short as to save labor, consumables, and the like; the ultrasonic welding module works with the production line of automation equipment and performs automatic welding under computer control;
* No excess heat will be generated from ultrasonic welding, especially in food packages, which suggests that heat-sensitive products such as food and beverages will not be affected and so the quality of food will be preserved better;
* If there are such contaminants as liquids, oil, or powder in the seals of packaging bags, tight sealing will be by no means affected during welding;
* Since welding a combination of materials will not produce contaminants and the amount of fusion welding between materials inside is quite negligible, products inside will not be affected by welding. In addition, processed food packages are eco-friendly and renewable, and expensive and pollution-prone ancillaries are not required during processing, thus greatly reducing the operation costs;
* Stable welding and prolonged service life;
* Welding products can be designed for different non-standard equipment products according to customer requirements.
