Do you have Questions?

Here are the answers to some frequently asked questions about induction sealing. If your question isn't listed here, feel free to contact us directly.
Induction sealing is a non-contact heating process that bonds a foil liner to the container’s rim using an electromagnetic field. This creates a hermetic, tamper-evident seal.
- Tamper evidence for consumer safety
- Leak prevention during shipping and handling
- Extended shelf life by preserving freshness
- Product integrity against contamination
- Plastic (HDPE, PET, PP, PVC) and glass containers
- Cap diameters up to 140 mm are common; smaller diameters usually seal moreefficiently.
Yes, they work with:
- Liquids (beverages, oils, chemicals)
- Powders (coffee, spices, protein mixes)
- Hot, chilled, or room-temperature products
Yes. Power rating (kW) is the measurable factor that determines whether a system can handle your container size, line speed, and liner type.
- Align the sealer with your conveyor and containers - Maintain consistent coil-to-cap distance - Establish an operating window (power, speed, distance) through testing
- Incorrect power or dwell settings
- Misaligned sealing head
- Contaminants on the rim (oil, dust, moisture)
- Incompatible liner or cap design
Yes. Glass containers can be sealed with the correct liner and cap design.
- Visual inspection for uniform bonding
- Peel tests for adhesion strength
- Leak tests for liquid products
- Regular QA sampling across production runs
- Clean sealing coils and guides
- Check coil alignment regularly
- Verify power supply output
- Keep logs of preventive maintenance
Yes. Liners are made from FDA-approved, food-grade materials when specified. Always match liner type to product chemistry for safety.
