Ensuring effective sealing in stick pack packaging is crucial to prevent leaks, maintain product integrity, and extend shelf life. Various sealing options are available, each suited to different product types and packaging requirements: 

1. Heat Sealing 

This common method involves applying heat and pressure to thermoplastic materials, causing them to fuse. Heat sealing is widely used for its reliability and strong seal formation.  

2. Ultrasonic Sealing 

Employing high-frequency ultrasonic vibrations, this method generates heat through friction, sealing the materials. Ultrasonic sealing is precise and energy-efficient, suitable for various applications. 

3. Easy-Open Seal Options 

To enhance consumer convenience, easy-open features can be incorporated into stick packs: 

These features improve user experience by simplifying access to the product.
