The sealing quality of aluminum foil sealing film directly affects the shelf life and safety of the product. By standardizing operations, optimizing parameters, and strict quality inspection, sealing problems can be significantly reduced, and packaging reliability can be improved. Today, we will introduce the key control points during the sealing process of the sealing film.

1. Temperature and pressure adjustment

Excessive temperature: may cause the sealing film to burn or deform.

Low temperature: Poor sealing and easy peeling.

Uneven pressure: may cause the sealing edge to curl or delaminate.

2. Sealing time control

It is generally recommended to wait 1-3 seconds, and the specific time should be adjusted according to the material thickness and machine performance.

High speed production lines can shorten the time, but it is necessary to ensure that the sealing meets the standards.

3. Equipment calibration and maintenance

Regularly check the heating element, pressure sensor, and flatness of the sealing machine's pressure head.

Perform air pressure testing before starting up daily to ensure stable operation of the equipment.
