Prepare the film roll: Ensure that the film roll is the correct size and type for the side sealing machine. Check the film roll for any damages or defects before proceeding. Open the film loading area: Access the film loading area of the side sealing machine. This area is usually located near the sealing mechanism. Mount the film roll: Insert the film roll onto the film holder or spindle in the loading area. Make sure the film roll is properly aligned and secured in place. Thread the film: Locate the film threading path indicated by arrows or guides on the side sealing machine. Begin by pulling the leading edge of the film from the roll and threading it through the designated path. Tension and alignment: Once the film is threaded through the machine, ensure proper tension and alignment. Some side sealing machines have tension adjustment knobs or mechanisms to control the film tension. Secure the film: Once the film is properly threaded and aligned, secure it in place. This may involve engaging film clamps or using manual or automatic film locking mechanisms provided by the side sealing machine. Test the film feed: Before starting production, perform a test run to verify that the film is feeding smoothly and without any issues. Adjust the tension or alignment if necessary.
