Automatic packaging machinery is widely used in various industries for packing products efficiently and securely. These machines use shrink film to tightly wrap around the product and then shrink it using heat, resulting in a tightly sealed package.
L-sealing tunnel vacuum machines are a type of automatic shrink packaging machinery that is commonly used in the food industry. They are ideal for packaging perishable food items such as meat, fish, and vegetables, as they remove air from the package, which helps to extend the shelf life of the product.
The L-sealing tunnel vacuum machine works by first wrapping the product in a shrink film using an L-shaped sealing bar. The sealing bar seals the film on three sides, leaving one side open. The product is then placed on a conveyor belt that carries it through a tunnel where it is exposed to heat. The heat causes the film to shrink and tightly seal around the product.
During the process, the vacuum removes the air from the package, creating a vacuum seal. This not only extends the shelf life of the product but also helps to maintain its freshness and appearance.
L-sealing tunnel vacuum machines are highly efficient, as they can pack multiple products simultaneously. They are also easy to operate and maintain, making them ideal for use in production facilities with high-volume output.
