Ultrasonic Paper Cup System

This ultrasonic paper cup system is a dedicated welding accessory for paper cup production. It is equipped with an ultrasonic generator, transducer and customized welding head. High-frequency mechanical vibration creates frictional heat to melt the PE coating on paper cups and achieve bonding under pressure. No adhesives are needed for sealing side seams and cup bottoms. It is compatible with most mainstream paper cup forming machines and standard cup sizes. Designed for continuous factory operation, it runs steadily and delivers consistent sealing quality.

Core Advantages

1. Glue-free Sealing, Food Safety Compliant

It replaces traditional gluing process with no adhesive residue or solvent precipitation. The finished cups are safe for hot and cold drinks and meet food contact standards. The working environment is clean, odorless and eco-friendly.

2. Firm Sealing & Stable Yield

It provides even welding energy for tight, leak-proof and neat seals. Problems such as paper tearing and incomplete welding are effectively avoided. The product quality stays consistent during long-hour continuous production, reducing defective products.

3. Cost-effective & Easy Maintenance

It cuts costs on adhesive purchasing, storage and pipeline cleaning, and saves labor. With mature structure, it rarely suffers from glue blockage or overflow. Low maintenance frequency ensures stable production efficiency.

4. Wide Compatibility & Flexible Adjustment

It works well with single-sided and double-sided PE coated paper for various paper cups and containers. With simple replacement of welding heads and debugging, it can produce products in different sizes to meet diversified production needs.

5. Durable & Well-protected

Key components are made of premium materials with low heat generation and long service life. Built-in overload protection copes with normal working condition changes and reduces component damage risks.
