The four-side seal product is a packaging form in which all four sides of the bag are heat-sealed. The most common one is alcohol disinfection tablets. Our company specializes in the production of alcohol swab packaging machines and wet wipes packaging machine, using the form of four-side sealing, which has good product sealing.
Four-side-sealed bags are usually packaged in two halves with a whole film. As long as one side is aligned during production, a better packaging effect can be obtained, and the requirements for packaging machinery are also high. However, after each edge is uniformly heat-sealed, the finished product has better sealing performance.
