Ultrasonic Seals are quickly becoming a popular sealing option for food packaging. This method uses sound waves to create a secure, airtight seal that is resistant to tampering and spoilage. Ultrasonic seals are created using two opposing surfaces, such as two pieces of plastic film or foil.
The surfaces are then vibrated at high frequency, causing them to fuse without heat or other materials. This creates an extremely secure bond that can withstand extreme temperatures and pressures while providing a reliable seal.
