Hot Seal Aluminium Foil Manufacturing Process
The production of hot seal aluminium foil at Huasheng Aluminium involves a specialized manufacturing process:
- Aluminium Rolling: The process begins with rolling Aluminium sheets to achieve the desired thickness.
- Coating Application: A heat-sealing coating is applied to one side of the Aluminium sheet, often a polymer that becomes activated when exposed to heat.
- Curing: The coated Aluminium undergoes a curing process to ensure proper adhesion and activation of the heat-sealing layer.
- Slitting and Packaging: The foil is then slit into rolls of the required width and packaged for distribution.
Considerations for Usage
To ensure optimal sealing conditions and compatibility with your packaging materials, follow these considerations:
- Optimal Sealing Conditions: Follow recommended sealing temperature and pressure guidelines for the best results.
- Compatibility Testing: Conduct compatibility testing before full-scale production to ensure the hot seal foil works effectively with your chosen packaging materials.
