Continuous sealing is a packaging process that uses heat to seal materials, such as plastic or foil, in a continuous flow. This method is commonly used in industries like food packaging, where products need to be sealed quickly and efficiently to maintain freshness and prevent contamination. The sealing machine operates by applying heat and pressure to the edges of the packaging material, creating a strong bond. This technique is beneficial for high-volume production, as it allows for rapid sealing without interruptions. Continuous sealing machines can be adjusted for different materials and thicknesses, making them versatile for various applications, including snack foods, pharmaceuticals, and cosmetics.
