A manual induction sealer for 20-80mm containers uses electromagnetic induction to create a tamper-evident and leak-proof seal on bottles and jars by heating a foil liner. These portable, 500W machines are designed for small to medium-scale operations and are commonly used in the food, cosmetic, and pharmaceutical industries. The process involves placing the container with the foil-lined cap under the machine's sealing head and activating it, which generates heat to melt the foil and create a hermetic seal. 

Features and function

• Sealing mechanism: Utilizes electromagnetic induction to heat the aluminum foil within the cap liner, which melts and seals to the container's rim.
• Container compatibility: Suitable for sealing a wide range of non-metallic containers, including plastic bottles, glass jars, and other packaging materials, with a 20mm to 80mm diameter.
• Seal integrity: Provides tamper-evident, moisture-proof, and leak-proof seals, protecting the product and extending its shelf life.
• Portability: Compact and lightweight for easy use in various locations.
• Power: Typically operates on a standard 110V/220V power supply and consumes around 500 watts.
• Manual operation: Requires a user to hold the sealing head over the container, making it ideal for low-volume tasks. 

Key benefits

• Enhanced product protection: Prevents contamination, leakage, and spoilage.
• Tamper evidence: The seal's integrity shows if the package has been opened.
• Cost-effective: A more affordable solution for businesses that don't require continuous or automated sealing.
• Versatile: Can be used for a variety of products and packaging types. 

Important considerations

• Material limitations: Not suitable for sealing on metal caps, bottle bodies, or certain types of film.
• Continuous operation: Avoid prolonged use beyond the recommended duty cycle to prevent overheating.
• Proper placement: Ensure the sealing head is positioned correctly for a consistent seal.
• Maintenance: Keep the sealing head clean to maintain performance and electrical safety checks are important.
