company news about Ultrasonic Packaging Welding

Ultrasonic packaging welding is an essential element in the plastic goods industry. Ultrasonic technology has found its way in a wide range of applications. Thanks to the installation of ultrasonic cutting and welding systems in packaging plants, it is possible to cut and seal packages of every shape and size, from tubes to thermoformed blisters.

The packaging sector is where ultrasonic technology finds a broad spectrum of uses: installing ultrasonic enclosing systems on a classic line, it is possible to solder and incise plastic made packaging of any kind and dimensions, from tubes to thermoformed blisters. Soldering sonotrodes remain cold during such procedure, thus avoiding potential damage to heat-sensitive materials. In addition, this cold process allows to reduce machinery maintenance and cleaning costs, since tools don’t get contaminated with residual particles. Therefore, ultrasonic instruments not only grant optimized production times but keeps aesthetic airtight closing properties intact.

The packaging solutions where ultrasonic is most commonly used are:

1. Step by step welding;
2. Continuous welding (for vertical and horizontal flowpack);
3. Multilayered welding (aluminium with low, medium or high-density polyethylene);
4. Blister isolating with PET, PBT, PVC;
5. Injection moulded parts welding;
6. Caps sealing for the beverages industry;

Advantages of ultrasonic packaging welding：

1. No foreign particles on the binding surface

2. Nonstick gear

3. Reduced processing times

4. Less cleaning efforts

5. Shorter welding and cooling times

6. Increased production speed;

7. Lower energy costs;

8. High quality welding in contaminated area;

9. No warm up time

10. Sonotrodes work cold and remain clean longer

11. Maintenance or cleaning tasks not required;

12. Eco-Friendly

13. No need for teflon tape replacement
