To avoid the sealing problem of aluminum foil sealing film, the key is to do the following 5 things:

1. Material matching:

The material of the bottle and aluminum foil sealing film should match (such as PP bottle with PP base film)

Corrosive contents require special coated aluminum foil

2. Parameter calibration:

Temperature: generally 170-210 ℃ (different materials have different temperatures)

Pressure: 0.3-0.6MPa

Time: 1-3 seconds (can be shortened on high-speed lines)

3. Equipment maintenance:

Clean the heating head daily

Check the flatness of the indenter every month

Regularly calibrate the temperature control system

4. Quality inspection:

Measure the sealing strength every 2 hours (standard ≥ 1.5N/15mm)

Sampling inspection for sealing (staining or vacuum testing)

Check if the seal is flat and free of bubbles

5. Environmental control:

Keep the bottle mouth dry and clean

aluminum foil sealing film storage should be moisture-proof

The temperature and humidity in the workshop should be stable

Simply put, it means using the right materials, adjusting the machine, checking frequently, and creating a good environment. Every time you change batches, try sealing 100 pieces first, and then proceed with batch production if there are no issues.
