Ultrasonic sealers employ high-frequency vibrations to generate heat through friction, enabling the bonding of plastic materials without the need for adhesives or external heat sources. This technology is particularly effective for creating airtight and watertight seals in packaging, making it suitable for a wide range of applications including food, beverage, pharmaceuticals, and personal care products. The process is efficient and can be integrated into automated production lines, offering a reliable method for sealing rigid containers, attaching fitments, and ensuring product integrity and safety.

Typical products and applications include:

• Beverage cartons with spouts or fitments: Sealed using ultrasonic welding to prevent leaks and tampering
• Dairy or juice containers: Plastic caps or pouring spouts attached securely without adhesives
• Pharmaceutical containers or vials: Sealed for sterility and tamper-evident packaging
• Personal care packaging: Snap-on fitments or flip-top lids welded to bottles or tubes
• Portion-control packs or pods: Sealed with precision for single-serve products in foodservice or household use

Additional Considerations:

• Delivers clean, strong seals: Creates bonds without added materials or residue
• Supports tamper-evident and leak-proof packaging: Ideal for safety-sensitive applications
• Reduces material waste: Uses only the packaging material itself—no glue, tapes, or extra layers needed
• Compatible with various plastics: Works on PE, PP, PET, and laminated materials
• Efficient and scalable: Suitable for high-speed lines and integration with filling and closing systems
