Due to environmental compliances, HDPE bags and LDPE bags are rapidly being replaced by PP non-woven fabric bags. Johnson Plastosonic provides state-of-the-art Indian-made Ultrasonic Generators & Horn Assembly for Bag Making Machines, offering continuous high-speed fabric sealers for bag-making applications.

Ultrasonic Sealers / Welders for Film and Fabrics

Ultrasonic Sealers and Welders are advanced tools used to join or seal materials like films and fabrics through ultrasonic energy.

What are Ultrasonic Sealers/Welders?

Ultrasonic Welders use high-frequency ultrasonic vibrations to create a bond between two pieces of material. These vibrations are applied under pressure to generate heat through molecular friction, melting the material at the joining point without the need for adhesives, fasteners, or external heat sources.

• No adhesives or contaminants are required, making it ideal for sterile environments.
• Seals are formed quickly, increasing production efficiency.
• Creates durable, airtight, and watertight seals.
• Suitable for delicate materials like thin films and fine fabrics.
• Focused ultrasonic energy minimizes waste and reduces overall power consumption.

• Eco-Friendly: Eliminates the need for chemical adhesives and reduces waste.
• Cost-Effective: More economical compared to traditional heat sealing methods.
• Material Versatility: Capable of handling a wide range of materials and thicknesses.
• Consistency: Ensures uniform sealing quality.

• Thermoplastics: Such as polypropylene (PP), polyethylene (PE), and polyester (PET).
• Non-Wovens: Materials used in medical or hygiene applications.
• Laminated Films: Used in packaging or industrial applications.

• Medical Products: Sealing films for IV bags, blood bags, surgical drapes, and gowns.
• Packaging: Food packaging, flexible pouches, and blister packs.
• Textiles: Non-woven fabrics, filters, and synthetic materials for clothing or industrial purposes.
• Industrial Uses: Automotive components, waterproof products, and banners.
• Consumer Goods: Sportswear, baby diapers, and air or water-inflatable products.

• Material Compatibility: Ensure the welder matches the materials being joined.
• Frequency: Common ultrasonic frequencies are 20 kHz, 30 kHz, and 40 kHz, with higher frequencies used for more delicate materials.
• Power Output: Depends on the thickness and type of material.
• Automation Level: Options range from manual to fully automated systems.
