SEALING MACHINES

A sealing machine, also known as a heat sealer, is a device that uses heat to create airtight and watertight seals on packaging materials like bags, pouches, and containers, ensuring product protection and preservation. 1. Heat Sealing:- The most common method involves using heated bars, irons, or dies to melt and bond thermoplastic materials together, forming a strong seal. 2. Other Sealing Methods:- Some machines use ultrasonic vibrations to create seals, or electromagnetic fields to heat a foil lining within a cap, creating a seal. Types of Sealing Machines:- 1. Handheld/Impulse Sealers: These are portable and use a heated bar to create seals. 2. Desktop Sealers: These are larger and more powerful, often used for higher volume sealing. 3. Automatic Sealers: These machines automate the sealing process, often used in industrial settings. 4. Vacuum Sealers: These machines remove air from the packaging before sealing, extending food shelf life. 5. Carton Box Sealers: These machines seal the flaps of boxes to ensure contents are secure during transit and storage. 6. Zipped Bag Sealers: These machines create an airtight seal along the zippered portion of the bag. 7. Foil Sealing Machines: These machines seal plastic jars or bottles, ensuring airtight preservation of contents.
