Sonic Industries Wad Sealing Machine: Reliable, Efficient & Tamper-Proof Packaging
In today’s competitive packaging landscape, maintaining product integrity and tamper evidence is critical—especially in industries like pharmaceuticals, food, cosmetics, and chemicals. A key solution for this need is wad sealing, which ensures airtight sealing of containers with foil or liner inside the cap.
Sonic Industries, a leader in advanced packaging machinery, offers cutting-edge Wad Sealing Machines built for speed, precision, and safety. Whether you're a small-scale producer or a high-speed manufacturing unit, Sonic’s machines provide consistent, secure seals that protect both your product and your brand.
What is Wad Sealing?
Wad sealing involves bonding a foil-based liner (also called a wad or induction liner) to the mouth of a container using induction heating. The wad is placed inside the cap; when the capped container passes through the machine, electromagnetic energy heats the foil, causing the sealing layer to bond tightly to the container’s rim.
This method ensures:
-
Leak-proof packaging
-
Tamper evidence
-
Extended shelf life
-
Protection against moisture, oxygen, and contamination
