A sealing machine, also known as a heat sealer or bag sealer, is a device used to seal various types of packaging materials. It is commonly used in industries such as food packaging, pharmaceuticals, electronics, and manufacturing. The sealing process creates an airtight or watertight seal, ensuring product freshness, safety, and protection from contaminants. The specific type of sealing machine required will depend on the packaging material, production volume, and sealing requirements of the product being packaged. Â
