Compared with standard dispensing bags, tubular packaging can directly pack liquid foods, while its central emptying design is another advantage. Tubular packaging is a slender, tubular packaging bag with a top seal and tear device that conforms to the product's shape and is manufactured using a longitudinal process.
The heat-sealable packaging material is removed from the web, divided into two lengths, and then fed into a forming tool to produce a tubular wrapper. The sealing tape is fed between the forming tube and the film material to form a tight longitudinal sealing zone. With the combined sealing device, the bottom seal of the empty bag and the top seal of the filled package can be performed simultaneously. The packaging machine is equipped with a dividing device that separates the filled and sealed tube bag from the remaining packaging material.
