| Advantages of the platen sealing system |
|
|
Sufficient process time. |
|
|
Constant and relatively low sealing temperature over the full sealing platen. |
|
|
Low energy cost. |
|
|
Flexibility to seal a range of lid materials. |
|
|
Proportional heat control with only +/- 5oC variation. |
|
|
Uniform pressure distribution over the full platen surface. |
 |
Heat transfer to product is avoided. |
| |
Absorption of sealing load within the station. |
| |
Separation of indexing and sealing functions. |
| |
Constant and uniform seal quality also during start-up. |
