Introduction
The principle of ultrasonic welding is to use high-frequency
vibration to melt the part of the contact material and achieve
welding effect after cooling. So all thermoplastic materials can be
ultrasonically welded. The beverage lid we saw in this article is
the lid and the carton. First of all, let's analyze the material:
the lid is plastic, and the beverage box is in line with the
material, including paper, PE, aluminum foil. When welding, plastic
and PE are in contact. Obviously, these two materials are
thermoplastic materials, and both can be ultrasonically welded.
Therefore, ultrasonic welding is very practical.
Ultrasonic welding instead of glue to fix the lid of the beverage
box:
1. Avoid the harmful substances of glue contaminating the beverage.
2. Good tightness, not easy to leak.
3.Ultrasonic welding is not affected by time, it is permanent and
firm, and the glue will usually crack after standing for a long
time.
4. Save labor cost, adopt ultrasonic welding, the whole welding
process is about 2 seconds, fast and convenient.

Service and shipment
Applicable in Packing area
PET packaging
In PET applications, ultrasound can quickly reach high melting
points and increase yield. Sealing and separation of blister can be
realized,
Kaifeng and genuine anti-counterfeiting functions can also be
easily implemented.
Soft drink packaging
Ultrasonic welding is particularly suitable for coated cardboard
packaging materials. Although the product is wet, it can still
ensure the tightness of the weld seam, and it does not matter
whether it has an aluminum film. The nozzle can be integrated
normally. Short sealing time and high yield. Repeatable welding
parameters ensure consistent seal quality.
Film packaging
Ultrasonic energy safely separates residual product in the weld
zone to ensure absolute sealing. So that it can be significant
Reduce the number of packaging leaks and increase product
durability. Lingke Ultrasound in stand-up bag, zipper bag and hose
bag
This advantage is fully demonstrated in longitudinal continuous
welding and horizontal intermittent welding.
Shell & top cover
The sealing of the top cover film, the welding of the sealing ring
and the sealing of the filter packaging are the most important
kinds of solutions using ultrasound
To the application. The welding mold positions the film by vacuum.
Heating-free molds ensure durability and protect the product.
