Product type
Induction seal caps are a type of closure used in the packaging industry to provide tamper evidence and extend shelf life for products. These caps consist of a plastic outer shell with an inner layer of foil that is sealed to the container using induction heating. This process creates a hermetic seal that protects the contents from contamination and leakage.

| Seal type | Foil induction seal |
| Diameter range | 20mm to 120mm |
| Thickness | 0.5mm to 2.0mm |
| Temperature resistance | Up to 100°C |
When selecting induction seal caps, consider the size and material compatibility with your containers. Specify the required diameter and thickness based on your packaging needs. It's also important to consider the sealing temperature and any specific certifications required for your industry, such as FDA compliance for food packaging. Quantities can vary based on production needs, so be prepared to discuss your order volume.
