1. When plastic packaging photos, it is necessary to put the sealed end of the plastic packaging film in front, and ensure that the plastic packaging film can completely cover the photos, then insert the photos into the entrance of the plastic packaging machine smoothly, hold the photos in the process, and release your hand after the plastic packaging machine can swallow the photos automatically.

2. When inserting photos and plastic films into the plastic packaging machine, keep them horizontal, and don't tilt, otherwise it is very easy to block the entrance and exit of the photo packaging machine.

3. The reason why the sealed end of plastic packaging film needs to be in front is because if the unsealed end is in front, it is very easy to wrinkle in the process of plastic packaging, and it may even cause the plastic packaging film to roll up and cause blockage.

4. If the above situation causes the plastic sealing machine to be blocked, the photos and plastic sealing film should be taken out immediately, starting from the film opening and film returning operations.
