The heat-sealing process involves several key steps to ensure a strong and reliable seal:
1. Preparation:
Ensure that the surfaces to be sealed are clean and free from contaminants[3].
2. Heating:
Apply heat to the thermoplastic layer of the thermo seal heat-sealing foil using a heated seal jaw or welding bar[5].
3. Pressure:
Apply pressure to the overlapping surfaces to ensure proper bonding[5].
4. Cooling:
Allow the sealed area to cool and solidify, creating a hermetic seal[5].
1. Handheld Heat Sealers:
These are portable devices suitable for low-volume production and on-site sealing[3].
2. Constant Heat Sealers:
These sealers maintain a constant temperature, ideal for sealing thicker materials such as barrier foil liners and laminates[3].
3. Impulse Sealers:
