How Many Sealing Methods Are Used in Tube Filling Machines?
Tube filling and sealing machines are widely used in cosmetic, pharmaceutical, food, and chemical industries.
Different tube materials require different sealing technologies to ensure product protection, appearance, and shelf life.
Choosing the correct sealing method is important because it affects sealing strength, production efficiency, leakage prevention, and compatibility with plastic, laminated, or aluminum tubes.
In this article, we will explain the most common sealing methods used in tube filling sealing machines and their typical applications.
1.
Hot Air Sealing Hot air sealing is the most common sealing method for plastic and laminated tubes.
The machine heats the inside of the tube end with hot air, softening the material.
The tube is then pressed together to form a strong seal.
